content: We are looking to upgrade our line. We currently have a DDM Novastar LE40V, which has been great for us, but we are looking for a few specific new features:* Conveyor system (less human board handling)* 60+ Yamaha CL Feeders (industry standard, inexpensive, easy to swap)* 0201 Capable (for future needs, implies spindle x/y instead of belt, at the very least would be better at 0402)* Good Software (hard to evaluate before purchase)* Inexpensive (cheap Chinese, instead of expensive Juki, Yamaha, Samsung, etc)We actually don't really care about throughput - we aren't high volume. But faster isn't a bad thing!This forum has so much great information, I want to give back some of my research, and ask for suggestions.I have narrowed my short list of units that meet our requirements to:1. YXing SMT660**https://www.zjyingxing.com/products/pick-and-place-machine-smt660-with-6-heads-64-feeders-ID259.html** Rebranded HW-T6SG-64F** 6 Heads** May not really be up to 0201?** 64 CL Feeder capable** $11,300 on Alibaba2. YXing SMT880**https://www.zjyingxing.com/products/pick-and-place-machine-smt880-with-8-camera-80-feeders-ID308.html** 8 Heads** 80 CL Feeder capable** $15,200 on Alibaba3.

We may end up doing a big package deal with them.Can any of you with machines from the above manufactures give a review? I would greatly appreciate it, as would many others on this forum. I will make sure we share our experience once we take the leap with one of these.Thanks!Jason Daughenbaughhttp://aed.pro

content: We have used two Yingxing SMT660s for about a year now (2018 models with the single conveyor). They are rebadged HW-T6SG-64F developed by Beijing Huawei Guochuang (http://www.smthw.com), although I believe YX buy them in part form and assemble themselves as there are some subtle differences from the other HW-T6SG-64F clones with things like fixings, etc. You can also buy them for export from Wenzhou Zhengbang. Both YX and ZB OEM them under license.Ours do 0402 with ease. We have no requirement for 0201 so haven't tested them. You used to be able to order them with belt X axis so be sure to specify you want the ball screws if they are still optional. For component detection there are two cameras - a high quality single camera and a smaller but much faster camera for each head that can process each simultaneously for speed (so 6 cameras or 8 on the SMT880). We only use the high quality camera for 32 pin chips and above, the fast cameras work well for everything else (including checking polarity on LEDs, etc).The software is not developed by YX and is provided by Huawei Guochuang and rebadged depending on which OEM is supplying it. The main software itself is a .NET WinForms application which although obfuscated can be quite easily converted back into source code and modified to suit. We needed to do that to fix a couple of bugs, and adapted the workflow to fit in with our processes. The software code is horribly structured, but is actually quite comprehensive and as all of the machine control, visual processing, etc, are handled there you can effectively take control of the entire production process. We use the mark camera (down facing) to check 2D bar codes on each board in an array to record exactly which component batches have been placed on each board, and to automatically skip "crossed out" boards without having to set it up manually. We also replaced the library functions to use our existing inventory system.(If you are interested in using the software I can share further, but it is worth noting it comes with another .NET library that exposes just the hardware interface that you can plug into other software by writing an interface.)They have 64 CL feeder slots, can support 48 trays and 48 vibratory feeders with the supplied software (but with the code you can adapt that as needed). Realistically you can place 8 trays on the bed at once. It is worth noting that the UI for setting up trays is very simple to use, and supports using external tray feeders if you have need for them. You can pick components from anywhere within the X-Y working envelope and have control over speeds, heights, etc at each step. Re-calibrating the machines is a simple process which you are guided through, although ours was pretty good out of the crate which suggests they QC each before it leaves them*. There are helpful shortcuts for time consuming tasks such as picking the centroids for the outer pneumatic feeders and having it update all the others for you. The English translations are mostly good, with only a few Google Translates needed. I got the impression that quite a lot of development hours went into the software, which is not always the case with cheaper Chinese products.We looked at a few similar options when choosing the SMT660s and ultimately chose them because for around $10k USD (at the time) you got a lot of hardware for not a lot of dollars.TBH I'm not sure the 8 head version justifies the extra cost as the rest of the machine is identical.* Finally worth noting that we had a failure of a front side controller board out of the crate where the input SMEMA interface was damaged and shorted it out. Yingxing sent a replacement out FOC (shipping at cost), so the warranty support was there. This wasn't picked up in QC because they test the machines in isolation.

content: Chinese machines are crap! Not useful in a production environment. I contacted all above companies and followed a few people who had experience with them. So far I am not aware of one single person getting use out of them.If anyone is interested I have a top rated Assembleon Sapphire for sale with $25,000 worth of spare parts. It uses Yamaha CL feeders and get down to 0201 reliably. These are rebadged Yamaha GEM machines that are known to be bulletproof! I have it for sale $14,000 in Chicago. It's hooked up and can be seen fully operational. Don't mess with the cheap chinese toys and step up to a real industrial machine that will last forever. Hits over 25,000 cph.

content: Follow the link below to a comprehensive YouTube video that shows programming an SMT880 from loading the coordinate file to setting and adjusting the parameters needed for a production run. It lacks audio and you must follow text overlays on the screen while observing the mouse pointer as well to fully track the progression. By the way, Jim Jiang at Yingxing is very responsive as I have needed spare parts and generally receive them in 2-3 days by paying a reasonable charge for expedited shipment.

content: There appear to be some "Chinese" machines that have on paper specifications that in some areas might make them OK, but without getting your hands on one and playing with the software and running a few PCBs its hard for anyone to say they are "Good". Autotronik machines are sort of chinese, fairly successful and at least "goodish", Faroad specifies a reasonable speed but in other regards is about 10+ years behind the kind of machine its conventional rivals are selling. Faroad has a UK seller, but who knows if they still will in 3 years? If you look at some of the videos of the "Chinese" machines the workflows are awful and sometimes baffling, they make you set things up the machine should know in the first place and all sorts of nonsense. They often lack toolchangers & love to make excuses, there is no excuse its stupid, a significant proportion of people who take delivery of these cheap machines immediately have to request a spare for a faulty or missing part, no excuse for that either.If you take the very bottom end of the non-chinese market then sure some of these machines should be very very scared of what the Chinese ones offer, DDM Novastar, & Mechatronika for example (the last one in particular because they are slooooow)When you buy a machine like this, there is more than just the headline price, local support & knowledge also matter, so does service & response time, so in the UK I would far rather go tohttp://www.intelligentdrives.com/if I needed a smallish but not necessarily fast machine than something I can get off Alibaba, at least with the UK machine I know exactly where to go if something goes wrong.In a different thread I said there were no equivalent machines coming out of China, I still think this is accurate, doesn't mean they aren't good or good enough, but they are not there yet on all fronts, sure generalisations are bad but low end western machines are in a difficult place anyway because their price performance ratio has never been excellent. Sometimes you can find some really odd differences, skip to printers for example and you can find the AP430 rebadged by multiple vendors. In the UK I can find that listed for £35k GBP, I have a quote on my screen for a brand new UK built printer with decent addons for £60k before discount, bargain you might think, but look again the AP430 takes a 29" (736mm) stencil but has a miserable print area of just 450 x 350 if you get the L version, so basically its not really a 29" printer.

content: Quote from: SMTech on March 13, 2019, 09:16:54 amThat would apply to any PNP machine, or in fact any bit of machinery. You have to do your homework. Broadbrush statements about how good or bad something is based on its origin are just really unhelpful. You either have to do the hard yards yourself, or have someone you implicitly trust to do it yourself. Even then sometimes you'll have something come up after you've done your testing. Its just how it is. I've bought some 'german' machinery ( German is supposed to be amazing right? ) that was just terrible. I've bought some Chinese gear that is great.

content: People need to keep perspective on these machines and remember they are $10k, not $100k or even $25k. They are not in the same market as the more established machines. If you are buying a $10k machine brand new, it is accepted that you are saving money by not having the same level of training and occasionally having to get your hands dirty with maintenance.That said, with the Huawei Guochuang/Yingxing machines above we've had very few physical issues. They were commissioned in March last year and have run thousands of boards without fault from the machine. (I'm ignoring user issues like loading the wrong components.) We quickly updated the software so I don't have a lot of experience with the OEM software but it is similar and functions well.The workflow that Proto shows in the SMT880/660 video above seems very cumbersome because it takes you through all the feeder setup stuff which you would not normally do just to change jobs over. It is just being shown as a tutorial. In most cases that is done once and the software retains them, and uses the chip library data to adjust heights/speeds/etc. I only ever touch the feeder settings on ours if I change the tray locations, I can't recall touching the pneumatic feeder settings in months.The normal 'new job' set up workflow on those machines goes like this:1) Import component list from your design software.2) Map the columns to the required data (e.g. X, Y, A, value, etc). You can optionally have fidcucial marks imported from the data (or you can set them later).3) Pick two known points in the data (typically two components on opposite corners) and locate them using the mark camera to automatically adjust the X Y data coordinates (mm/inches) into machine units (steps).4) Panelise/array the boards if needed. Data is cloned so you can adjust for any board in the array, but they retain the original links so you can still manage just the source data too.5) Use the SMT table window to map each component to a feeder, and settings like height, movement speed, the camera recognition algorithm to use, etc. Normally you set up your component types once in the global library and map them to the board components for each job. (The software will try and do that automatically where there value/type and footprint are the same. Once you have a working library built up you rarely need to touch the mappings.)6) It is a good idea to check positions for a few random chips and any critical ones for accuracy and jog them if needed. If your mark settings in step 3 are accurate you shouldn't need to make changes. You can use the feeder screens to test pick and use the component list to test placement.7) Run validation to check for errors and then load up the feeders and off you go.When opening an existing job you just do step 7.

content: Quote from: xdave on March 03, 2019, 02:26:28 pmI am very interested in this. You are doing exactly what I would like to do,capture serial numbers of the boards.I was looking at sniffing the serial port and directly talking to the machine. If there is a hardware extraction layer like you say that would be much easier to work with.The smt460 uses the same software, so it might be possible to increase its accuracy with manual software.

content: Quote from: INGMULTI on May 23, 2019, 12:31:39 amMy SMT660 has been great over the last 18 months. I recently needed to replace a camera on the unit and they were very helpful with supplying it.Software is fine and once you have played around with it you should be good. It's not super advanced and config is done with XML files that can be backed up incase your changes are not good.The Conveyor on the SMT880 machine is better than the one I have and the upgrade is pretty good. Supplied feeders have been great and I have not had an issue with any of them. Well worth buying as many of those as you can afford as you find them much cheaper.

content: Quote from: protoneer on May 23, 2019, 12:48:14 amI am also considering buying one SMT880 but I need a very specific workflow, in order to cut times required for setup.From what I understand, the machine software have 2 parts, one in which all 'teaching' is done, from where to source components and where to place, then create project file ( .qn file). Second part reads .qn file and actually execute the job.In order for me to optimize workflow, I must generate .qn file offline (and I must write some tools for that), when the machine is working on other project. But I do not know the details of that file. I asked Jim to send me a file, he send me something (not actually a .qn file, more like a copy-paste of something as a .txt file) which was helpful indeed, but my feeling is that there is something missing.If I am not asking too much, can you send me a .qn file to have a look at it? Preferably with tray components, not only feeders. I am only trying to see if it contains all the data I see in their software (pick coordinates, pick parameters -speed-delays, nozzle settings, vision settings, destination coordinates and placing parameters, etc). The file received from Jim contains some x,y coordinates and rotations but I got the feeling that something is not in that file. Or perhaps I understood wrong from videos, a project have one file with everything or it uses several files (ex. one file with pick coordinates, other with destination, etc) ?Thanks in advance for your help, my email is chendeflorian(at)yahoo.com

content: Quote from: pisoiu on May 23, 2019, 06:07:57 amNot so sure about the QN file. There are two parts to the setup. The machine setup and the actual job.MAchine settings include settings for each nozzle per feeder. Trays are simple , you set top left , top right , bottom left and bottom right. Then specify the rows and columns and the machine works out the rest.Job settings is just two fiducials and rest is components that link to a nizzle and feeder/tray. For each component you can also specify the camera to use for identifying.

content: Yes, this is pretty much what I understood from youtube videos.What happens after all machine setup for a project is done? What do you save on machine computer? One or several files? This/these are the files which I want to have a look at, because I want to try to develop a workflow which allows me to make machine setup (generate those files) elsewhere, without the help of the machine, while the machine performs another job. These are the files I kindly asked to share with me, if possible. Maybe you have files for some simple job, which does not contain sensitive data. I definitely do not want to share them or send them to anybody. I want to look at their content, to see if I can reverse engineer their structure, so I can create a workflow and tools to generate them offline.Job settings looks simple, like loading machine with components, load files generated by setup job and run.Thank you.

content: What you really need is to get them shared with the guy who writes PCBSynergy he seems to have Neoden and Charmhigh in there already and I think that does the step you are looking to streamline. No matter how slick your process gets some things just need checking or setting up on the machine for new jobs.If you are looking at doing other peoples boards there are a couple of things to look out forNot everyone is happy sharing the CAD files (which PCBSynergy can read) so may only supply Centroid & BOMNot every Centroid file is the same, the column orders often change, there can be extra ones or they may not include the part number or even value data, SMT Maestro is a free tool that can help with that (unless you write your own).Some software packages call even very standard package names weird things, which can get in the way of quickly telling the machine setup files what kind of part it is (e.g "SMD1002" instead of "0805")Rotation data should really be standardized (it is a standard) but in reality its a hot mess so package types where orientation always needs checking, if you are writing custom tools you can then apply rules that correct it.Customer defined packages frequently have the center defined incorrectly.If your machine setup files detail everything from feeder slot to nozzle used, because that's how these machines seem to work because the feeders are "dumb", and you change between jobs rapidly you need to be extra careful with inventory and knowing which feeder is which and whats on it. This is one of the many benefits of more expensive electronic "smart" feeders, I've seen some of these machines list electronic feeder options but their datasheets are so vague who knows if they or the software connected to them lets them be smart.

content: Thank you very much, those files really answered my questions. Pure gold.It looks pretty simple to work with them, they're xml.What surprised me was the feeder settings file. While machine settings and job setting seem to contain only what is needed for one job, the feeder settings seem to contain far more data than it is needed for one job. SMT660 have 60 feeders or so, but feeder file contains a lot more. Anyway, that's not important now.

content: (Read to the end, as the software has changed.)The qn fileswerejust binary serialised classes using the standard .NET serialiser up till at least version 190130_V3.3.2. The classes for the 'job data' are USR2 (pcb component information) and USR3 (machine mapped data). I forget which one holds the feeder/tray data without checking but I think it is USR2. They are highly version dependent (files serialised from one version will not work with another).If you use something like ILspy on the QiGn.dll assembly you can see the class definitions, and you can then work with them as needed. It's been a while since I reverse engineered ours so I am not certain if that assembly is obfuscated (the executable QIGN_COMMON.exe definitely is). If you find yours is then you can use freely available tools to deobfuscate it followed by a bit of tidying up and you should be able to compile and use it.We changed to use XMl serialisation from day one to make it simpler to integrate, and at cursory glance Protoneer's files seem to show the same basic data structures in a very similar hierarchy so it appears Huawei Guochuang have adopted that now as well. It would be helpful for future users if Protoneer could share the version number of the software so we have an idea when the change was made.

content: I am a bit unsure about 2 parameters from description of chinese machines, please somebody enlighten me:-"maximum movement range of Z axis", ex. 20mm. Does this mean that the tip of the nozzle, when retracted, is 20 mm above the pcb plane and the maximum usable component height is half of this value, to avoid bumping high components already placed on board?-"buffering range of suction nozzle", ex. 4.5mm. No clue. What is this?Also, some of new machines from boreytech are equipped with "flying camera system" and there is one camera instead of several low resolution cameras (one per head) plus one high resolution camera. I can imagine that new system occupies less space on machine board and maybe it makes more room for 2-3 extra feeders, and of course, it increases CPH a little. Aside from that, are there any pros/cons for this new system? Did anyone tried it on chinese machines?Thank you.

content: Just came back from Shenzhen and managed to visit Huawei Beijing Guochang's branch office in Shenzhen (manufacturer of the SMT550/SMT660/SMT880, Wenzhou YingXing is the legitimate distributor outside of China as clarified by them). It's a tiny office further away from the Shenzhen city center while their factory is in Beijing. Took a Didi (like your Uber and Grab elsewhere in the world) from the nearest metro station for the first time but was going into wrong building (YingXing sales representative gave an image of the large building next to it!). I was fortunate that a SMT550 has just arrived at this place although it is not being set up yet. And YES, I managed to measure the height of the SMT550. Without the feet and alarm light, it is around 77.5 cm which gives me around 2.5 cm of margin to go through my 80 cm door. Moving on the machine, it is a very solid and well built machine. Even the bottom is fully enclosed with no dangling and exposed wires. It could do down to 0201 like it's bigger brother SMT660 and SMT880 when the electric feeder (also Yamaha but I'm not sure what series is being used) is being used. It also supports the usual pneumatic Yamaha CL feeder up to 50 8mm. It also has rails and can be cascaded to other machine. Maximum component height is 8 mm. The software is exactly same like the SMT660 and SMT880. So, it's easy to migrate between different sizes of the machines. Here are some shot of the SMT550 (un-powered though).Rather than running the place solely as a showroom only and collecting dust, they actually run small PCBA services to the local market. There are 2 SMT880, 1 SMT660 and a SMT460 (obsolete and no longer offered and it is surprisingly as huge as the SMT880 and SMT660!). They cascaded a SMT880 and SMT660 in a line together with a semi-automatic stencil printer. They were assembling some ESP32 board that has components down to 0402, SOT-23-6, SOT-23, QFN-48 0.4mm. Throughout my 1 hour there, I took a look at those assembled panels from time to time to see how the placement accuracy fare. They are very accurate and spot on.I did drop by NEPCON Shenzhen 2019 too on this trip, although machine from ZhengBang are cheaper but it comes with less feeder and belt configuration (ZB3545TP, not published yet on anywhere at this time of writing). ZhengBang used to OEM from Huawei Beijing Guochang for the past few years but starting from 2019, they are on their own. Charmhigh was also there were showcasing their new huge machine (6 and 8 head that uses electronic feeder) which are totally out of my budget and of course that space constraint. Other machines on display are from the regular big boys (Yamaha, Panasonic, Juki, Autronik) are again out of my scope and requirements.I will probably get the SMT550 to replace my current machine. At USD7500, it definitely has better features than many machine even those priced well above it. Ball screw with pneumatic and electronics feeder, rails. At least, both Huawei Beijing Guochang and YingXing are upfront about their business relationship and that is fine with me. As long I get the proper support, I am more than happy. The flight, visa and accommodation only cost me around USD300 from Malaysia to Shenzhen and I'm glad I took the short trip!

content: $300 well spent. A similar trip for me is about $1500. On the face of it they look quite resonably built. It would really come down the software i suppose.

content: I brought directly from Hua Wei Guochang, I find them more honest then their so-called partner YX. I now own a T6SG, a 6 head version. I have no problems with this machine, works fine, goes down to 0201 with no problem (you have to use electric feeder instead of pnuematic ones for 0201) So i'll say this is one of the better chinese made machines. However that being said, i do hope they improve on the software UI/UX...James

I Checked up YX, and the street address on their website, doe not match teh big flash building displayed on their website. Those kind of thigns get you instantly disqualified in my purchasing decisions.. If they are operating out of a differnet building, and the product is fine, its a non issue.. But pretending like that is just dumb. A quick google maps look up and your done.Have you got a contact for Hua Wei Guochang

content: Quote from: efon on November 14, 2019, 09:18:19 amI don't have the answer but I would certainly hope your P&P would do that, otherwise I consider it a complete piece of junk. Compensating rotation based on feeder location (front or back) should not be a user problem to solve.

If you are going to put a feeder on the back rail, you have to add/subtract 180 degrees to/from the rotation angle you would use on the front rail. As long as you are well aware of this, it is no problem.Jon

content: Reviving this thread to see how the last few years of ownership experience has been with the SMT550.I need a machine pretty quickly and am considering a used Samsung CP45V neo or the SMT550. I have a few questions about the Chinese machineDoes it come with 50 feeders or is that Chinese to English sales talk and you have to supply your own feeders?If it comes with feeders, what size and how many or supplied?Any issues crop up over the last few years?How reliably can it place large lqfp parts with 0.5mm pitch?I have a couple of boards that are 12x14 inches. Is there a way to work with these without using the conveyer, which is limited to boards less than 8 inches wide?Thanks guys.

content: QuoteSupplier/reseller dependent question, you need to ask them personally. Just make sure if you want the electric feeder bank, ask for it, it's not installed by default but the pictures makes you think it's part of the deal.QuoteOne issue I have over a 6 months ownership is one of the valve for the feeder is malfunction. They sent me a replacement and it's an easy fix. Air supply has to be good, clean and strong. I initially have some issue with certain feeder not turning on but after adding better filter and draining air compressor vapor water more frequently, the problem goes away. Other than that, I'm already on the latest software now that has improved a lot over the old version (auto feeder location pick-up, footprint library, etc).QuoteI did 0.4 mm DFN and 0.5 mm LQFP-48 & QFN-48 which is fine but haven't use any larger QFP though.12x14 inches is tough. I just measured, I doubt it can fit because of the large HD camera sitting at the right hand corner. If you don't use the conveyor belt, you can arbitrary place a board anywhere on the machine. If there's 1 weakness on the machine, it has to be this, the PCB size limitation. I don't have any too large board so I'm okay but I can imagine someone having bigger boards.

content: Quote from: JMG on April 13, 2021, 02:44:50 amI have a Quad QSA30A, which is quite similar to a Samsung CP30. The Quad uses Quad electronic feeders instead ofSamsung's air-driven mechanical feeders. I think the CP30 through CP40 used the same generic software, the CP45 uses a newer generation, as well as the flip-mirror flying bottom vision scheme.Well, there was a LOT wrong with the QSA30 I bought at auction, and it took me some time to figure out the software.Now that I have it mostly figured out, though, it is quite amazing. My previous machine was a Philips CSM84, which was VERY basic. The software on the QSA30 is much more advanced. It runs on a PC with Windows 95, so you can back up files, load files from external sources, etc. The GUI allows pretty easy setup and testing of fiducial pickup, board array setup and component test picking. You get a pop up box that shows the alignment adjustment.When you create a new board file, it pulls in the component vision profiles from the part library. Once you have created your part library, it is quite easy. (I'm still having to enter the new parts as I come to them.)The Samsung software gives up after several mispicks of the same part, but then remembers what was missed on that board. After finishing the board, you fix the issue(s) and press start, and it places all the missed parts. That is VERY cool!I have not used the Chinese machines, but don't think their error recovery is as good as these mainstream commercial machines. I had No PROBLEM at all getting parts for my old QSA30 machine from the far East, so CP45 parts should also be easy to get for some time into the future. And, the brokers there did not charge me an arm and a leg for these parts.Jon

content: Thank you for your reply.So I took the plunge and ordered a SMT550 this week. It was a terrible experience and I'm having some regrets already. I was pushed in to buying it on alibaba and I could not pay by credit card. I tried 2 different cards and only when the total was split did a payment go through, after that nothing. So I had to incur massive PayPal fees to pay the remaining balance. I think when this was all said and done I'm in to about $500 in fees.I was under the impression the machine came with 50 feeders per the alibaba ad but apparently it does not, it comes with 15x 8mm feeders. So I ordered 5x more 8mm, 5x 12mm, 5x 16mm. Add in $60 to configure for 110V and the grand total before fees was $8760.If I had bought the ebay listed machine, from ebay, I could have had that machine with 50 feeders, per the listing, for $7950 done. I tried to get them to match this price but they would not move on price at all. Terrible customer service already, including blaming my bank for the card issues even though the bank did not see any transaction attempt on their end except the single one that went through over maybe a dozen separate tries. I'm now looking at a 45 day processing window before they ship even though the ad says they are in stock.I will wait for further comments until I see shipping info and figure out how I'm going to get this from the nearest port of entry to my address.
