content: Some customers ask me to give a video for Tronstol E1 desktop machine,this is the link:This is the link for E1 experience:https://www.eevblog.com/forum/manufacture/tronstol-e1-experience/msg4716536/#msg4716536There are some advantages of E1 PNP machine：For the hardware:1.Use 3D flying camera: laser camera flying shooting, greatly improving the accuracy and speed of desktop machines; It has three main features: (1). flying photography, (2.) recognition of footprint with micrometer-level accuracy,( 3). recognition of online nozzle size.2. XY-axis linear encoder full closed-loop motion control to avoid component step loss, this patent is only available from Tronstol.This can make sure the precision of E1. With the 3D flying camera and grating ruler can make sure the accuracy of 0201.3.Detachable feeder bank:you can install the reel&tape when the machine is working if you buy one more feeder bank.It is also easier to install the tape&reel than the traditional feeder bank.It also greatly reduces the time you need to change materials when mounting different boards. For example, if you need to mount 2 different boards, one side of the feeder bank can install materials shared by 2 boards, while the other side of the feeder bank can install with different materials. The three feeder banks can finish the placement of 2 boards. Because our software has a concept of material library, it greatly reduces the time for file editing. When you have more types of boards, the richer the information in the material library, and the shorter the time needed for marginal file editing...4.The mechanical structure of the placement head which can accept the component height more than 13mm.5.Automatic nozzle changer device:You can use six type of nozzles,it is same as you have 6 mount heads(This device need purchase separately）.6.5-million-pixel high-precision IC camera, which can be selected as a large or small camera according to your IC size...For the software:1. Friendly user interface design, convenient for customers to use.2.Increase the material library(which I said above): the same component does not need to be edited if you change different PCB.It really reduce the time to install the tape&reel and edit the stack information.You only need edit once for the pick height,pick delay...this function can really save your time.3.Offline software:you can edit you file in your computer.It will not occupy the machine.4.We continue to iterate and upgrade our software based on customer needs;you can download the newest software from our website directly.5. Various functions, including 90 ICs and 99 bulk material placement settings.6. Automatic correction of picking position,it help you edit the file more quickly.7.Flexibility in Mark selection:You can use none mark,one mark,two marks or any quantities of marks.8.Online video tutorial to help you quickly master how to use the machine...

content: I was taking a look lately to these USB connectors and the complexity on soldering and assemblyhttps://www.we-online.com/en/components/products/COM_3_1_SMT_TYPE_C_PLUG_HORIZONTALThere are some guidelines at least from Wurth for soldering this connector, looks like first BOT is soldered (Paste is applied and melted on the bot pads on this connector but connector not placed) an later on TOP with the USB C populated.https://www.we-online.com/components/media/o563289v410%20ANE009a_EN.pdfBut...., how can be the placement of this component automated? Can the PnP insert this connector on the side, or especial fixture is needed?Thanks and regards!

content: It explains in your second document: "Assembly of the USB-C plug (whether automatic or manual assembly is possible depends on the production equipment).".In most cases this would be hand installed. But if you had a very high volume product you'd make/buy a tool to insert them.There might be some info here:youtube.com/watch?v=gy9j16oixsY

content: Yes, it said both, but I was curious which kind of Machine or more specifically PnP is needed to being able to place it in this way.I ordered some PCBA to JLCPCB and at least them looks like do it by hand.It was needed to panelize the PCB in a way you keep a board outline or keep out which is bigger than the connector, of course to be able to insert it.Not sure if this method is used in mass production.Thanks!

I'd like to use them with a T-245 handle on a CD-1BQE station, but I'd buy a different handle if necessary.If you're not sure what I'm talking about, I uploaded a picture of tips for this application but designed to fit hakko irons.Yes, I did search google, jbc website, and this website with no luck.

I'm hoping to get the second iron off my bench, as space is at a premium. My workspace is only 100 ft² (9 m²). JBC has hundreds of specialty tips available, and I own quite a few, but nothing for inserts specifically.Quote from: digger on August 14, 2024, 08:49:29 pmNot quite, I think those are for melting plastic stakes that were formed into thermoplastic parts.Actually, on further inspection, they might be workable. There are stake tips in a few sizes and with the chamfered shoulders I might be able to make it work. I'll order a few and see how they do. Thanks!

content: I also use these brass tips for heatset inserts that sell on ebay and amazon for about 10$ a set and are compatible with Hakko 900M. Specifically for that I got a cheap soldering iron with no external station. It plugs directly into AC mains and can be left in a drawer when not needed. Temperature might not be that accurate but it's more than good enough and the M3 tip has been on for a year or so. No need to use the JBC for that.

content: Avoid the LT tips like the plague. The thermal coupling between the PT adapter and LT tip is crap!Always buy PT tips. Not only does the [Edit: much greater thermal mass] tip go right down into the heater barrel and pick up more heat, but the Curie point slug on the end is monitoring the temperature of the tip itself rather than the adapter. You also get to choose the tip temperature by which PT tip you buy.It's not even as though the LT tips are significantly cheaper, I don't know why they bothered.I've never bothered with a round nosed tip either, always a sloped or chisel tip. I used to be able to get a 0.5mm pitch 208 pin PQFP down in 2-3 minutes on a proto boards, including cleanup and inspection, just using a TCP iron with sloped tip, drag soldering and plenty of liquid flux.

Can framed stencils be recycled? - Page 1

timestamp: July 21, 2024, 05:48:28 am
content: I have accumulated quite a number of framed (470mm*370mm?) stencils in the past couple of years. The frames seem to be aluminum while the stencil sheet is steel. I can't break them apart because the manufacturer used strong glue and tape between the frame and stencil sheet. I'm wondering, is there any way to recycle these?

author: MR
author_rank: Regular Contributor
timestamp: July 21, 2024, 06:17:28 am
content: Of course - the frame is aluminum, the stencil is stainless. If you cannot or don't want to do that your recycler might do that for you.It took me a few minutes to disassemble a relatively large stencil, I only had to take off the tape and push the stencil down, the glue was still in-place attached to the frame, it could be hammered off.We also process Aluminum with our CNC so we recycle Aluminum anyway from time to time. I'd say it's worth at least 1-2 coffees.On the other side maybe the company which makes the framed stencil will take it back and make a new one out of it, talk with them if they're nearby. If you get the stencil from abroad, recycling is probably best.I think 1kg Aluminum (chips from the CNC) is worth around 2.50$ (closest nearby), a little bit further I'd get a little bit more for it here. Block materials are worth more. New material for processing is around 5-6$ per kg.

content: Easiest way to get the stainless off the alloy is heat, heating to over 150C will definitely cause the adhesive to let go, allowing you to separate them while hot. Then 2 piles of recycling and you are done.

author: liudr
author_rank: Contributor
timestamp: July 21, 2024, 02:10:56 pm
content: Thanks for the suggestions. The manufacturer is indeed overseas so it's not possible to ship the stencils back for recycling. I don't have a large enough oven (not for food) to cook the glue to easily separate the frame and the sheet. I know that we have a university nearby that takes aluminum scraps that they use for a shop class where they melt the aluminum for students to mold into pieces. I'll reach out to see if they are willing to recycle the whole thing.

content: Both Excellon and Gerber files are variants of RS-274, commonly called "G Code". But, one of them suppresses the leading zeros, the other suppresses the trailing zeros. In both cases, the decimal point is suppressed. There is a format specifier line that begins "FSLAX" and tells what the format is for the X coordinates, then after the Y it describes the Y format.It is most likely that Seeed's software didn't recognize your format specifier.There are various CAD/CAM packages that are meant to check Gerber and drill files. Also, cad packages have various options to set number of digits to send in the files, and where the origin is to be. I use Protel 99, and have to always set "use relative board origin" or the Gerbers and drill file do not have a common origin.Jon

The pattern also does not match.The most logical explanation is that you generated the drill file some time ago, then modified the PCB, generated new gerbers, but forgot to create a new drill file. What are the file dates? Do you recognize that hole pattern (especially the 4 holes in a rectangle).A lot of PCB design programs have a gerber viewer and can also load drill files. I use KiCad myself and it can to this. There are also online gerber viewers.

content: Gerbers/drill files should always, always, always be checked with a third party tool. Personally, I'm using the gerber viewer integrated in KiCad. Of course, I'm not designing my boards in KiCad as I wouldn't consider this "third party". Another good tip is to use the excellent online PCB analyzer from Eurocircuits to check your data.Your current project looks like a file mix-up (wrong/outdated drill file).

We have two primaries in series, which interleave a secondary...its just a prototype board, so wewont terminate the windings to the former pins, as when soldering them, the pins just melt out of the former plastic....so we will have the six winding ends coming out of the transformer....and we will solder these into PTHs in the PCB....however, we dont want to mix up the transformer winding ends. So we need like little coloured rings to go round them.Does such a thing exist? I have seen them for wires, but they are rigid and i think some elasticity will be needed. Possibly like a little split ring thing would do it.

I then downloaded this file with a standard serial communications program (in my case I used minicom).Then, I set up the feeders on the machine using the feeder menus. That was the whole process.Jon

Is there any software with which I could easily create a pcb panelization and upload the files to the machine? I found pcbSynergy on the web unfortunately there is a problem because there are a lot of errors during the conversion. I had an old kicad v4 project and the conversion went fine but unfortunately, the new version of kicad is probably not compatible with PCBSynergy. I can't imagine rewriting it manually into machine language. Is anyone able to help me?

Some issues have to be fixed with the Altium to Kicad importer then it should be possible to use Altium with Kikit as well.If you cannot generate the panel with your system you might go that route.

What diameter PCB hole for wire wrap socket pin? - Page 1

author: microMANIAC

timestamp: May 20, 2024, 02:40:45 am
content: I am designing a PCB for a piggyback board which will use a 40pin DIP wire wrap socket to pass through the board and connect to the parent IC socket. These pins were not dimensioned for PCB insertion and I suspect they need a bigger hole than would be used for a standard IC socket. I don't want to insert the press fit part of the pin like you would if you were actually wire wrapping, I just want the long thin part of the pin to go through the hole. Does anyone know what hole diameter I should use?

That's a bad idea, bordering on "won't work at all". The pins are much, much too thick, and will damage a regular stamped IC socket, and won't fit into a machined IC socket at all.

The WW to Dupont connection is super solid, and the dupont to IC socket one is snug. Maybe surprisingly, it works extremely well.

ENIG after SMT assembly - Page 1

content: I recently placed a JLCPCB order with a slightly unconventional board, where one side is a solid ground plane with its solder mask removed. The other side is more conventional and has been assembled with SMT components. My plan is to use the large flat conductive surface to calibrate some CNC equipment.Unfortunately I got a message from JLCPCB saying the boards had been damaged during assembly. In the past I haven't had a problem with a bit of comedic damage, so I've asked them to send the boards regardless. As in this case the boards dimensions are important for calibration, I asked if they could remanufacture them. I think there was some miscommunication, as they said they would repeat the ENIG process but not produce new boards.Is it even possible to ENIG plate fully assembled boards? Are there any problems I should look out for?Thanks!

I plan on using it as the first step in a calibration process, so only looking for an accuracy of around 0.5mm. I have a second step to hopefully dial in the accuracy further, but it needs a rough calibration to locate the fiducials correctly.JLCPCB wasn't able to repeat the ENIG process (no surprise) and ended up remaking the PCB. Fingers crossed it turns up without damage.

I tried (even good quality name brand) watercolor brushes and they became leaky fairly quickly. Additionally, they aren’t ESD-safe.Quote from: Hootis Tigglebits on April 17, 2024, 10:49:11 pmThe counterfeit Bonkote pens have a terrible reputation, becoming leaky much faster than the real ones, and not dosing the liquid well.See also:https://www.bonkote.co.jp/en/bonpenandhttps://www.bonkote.co.jp/en/counterfeit-goodsP.S. I have a strong suspicion that the actual physical manufacturer of the Bon Pen is Pentel, since they look identical to the Pentel Art Brush/Color Brush/Colour Brush, but with customized tips and ESD-safe materials tested to withstand solvents.

My DHL driver knows to leave packages with my neighbours when I am away from the office. This is easily set up in the DHL app.I will try to place my LCSC orders just after placing a JLCPCB order, as you then are offered discounted shipping.They are not quite as fast to ship as Digikey/Mouser/E14, and they don't have as consistent stock levels, but for common parts they usually have very large stock holdings and are substantially cheaper.I find them great when I am doing bulk orders for production. I am sure smaller orders via airmail would also make sense for hobbyists.

content: So from what is stated on their website (https://jlcpcb.com/quote/pcbOrderFaq/Different%20Design%20in%20Panel) it follows that the designs are considered different if any of the following is true:- there is a board separation method (v-score, mouse bites, etc.) used between sections of the 10x10 cm PCB that look like different designs- there are more than 5 sections that look like different designsQuoteIn other words: if you cut them yourself, no problem.In practice, however, I think I read someone mentioning that they wanted the customer to pay extra even when the designs were separated only by silkscreen. So then it likely also depends on the person verifying the order. I don't recall exactly where I read that, though.
