However, you will likely need the board in a Gerber format, not as a PDF.Did you try to contacthttp://www.qrpkits.com/mmr40.html? They had this as a kit, now retired, but they perhaps could be willing to share the documentation and the design files with you. If not, it is not too difficult to redraw it from the schematics and the existing layout file above using e.g. KICAD so that you can send it out to have it fabricated.

For 99.99% of them it is too much mucking around and error prone, when they can make more money from other clients.If you don't want to make it yourself, then you probably should redraw the PCB in a CAD package (Eagle, Kicad, etc).Alternatively, you might have luck with one of the PDF to Gerber converters, but I doubt it.

Then I'd import the DXFs into DipTrace (or the CAD software of your choice) and set the primary layer as pads. Then you could export it to a Gerber.The first PDF you posted would be problematic because it's two layers and they've got the bottom traces contrasted to the top layer.The second PDF could be converted easily.

In the future I might buy a few extra 12mm, as more and more ICs are being delivered on tape rather than stick nowadays.My order was based on what I had on my previous machine, which served me well over 8 years. Your mileage may of course vary.

Mixing SMT with through-hole - Page 1

timestamp: January 08, 2017, 02:35:58 am
content: I'm designing a suite of guitar effect stomp boxes and need to decide whether I design the PCB for SMT, through-hole or a combination of both. There are a few components like POTS, switches and jacks that are better suited to through hole components since they make up the physical/mechanical build of the box. My question is should I design the PCB to be 100% through hole or would a mix of SMT and through hole components be OK considering the potential for volume manufacturing? I'd appreciate any advice. Thanks.

timestamp: January 08, 2017, 03:07:25 am
content: For those I DIY, I use both for primarily the reason it's far simpler to DIY a single sided PCB and when using SMD the routing paths are more difficult to find, but with the addition of a few TH resistors onselectedNets, they open the paths for traces that would be tricky to find without other side wire links or a double sided PCB.For any volume you'd get them from a PCB house and double sided of course.For manufacture there will be other considerations, primarily the choice between Reflow (SMD only) or Wave soldering where components need be stuck down (SMD and TH).Adhered components can make rework more difficult when used.

content: In medium volume (say 100-10000 pieces) mix of SMD and through-hole is fine.In very small volume, through-hole could be cheaper as there's no need to set up stencils.Typically you will be quoted based on the number of pads / pins, plus a fixed setup fee (which is higher for SMD, but amortises quickly in volume). The fee per through-hole pin is considerably higher than per SMD pad. In this kind of medium volume the throughhole parts will typically be soldered by hand.I agree with you that it makes sense to stick with through-hole parts for connectors in medium-volume applications, as the SMD ones can be more hassle than they're worth. Won't be any problem for any factory / CM.

content: if you want someone to design you a custom PCB from the existing schematic, well, that's a schematic capture and layout job (maybe also a bit of a design job, seeing some of the original parts will be really hard to source and probably need replacing!)if you want to reproduce the boards from scans, as exact clones, you can probably get someone with photoshop/illustrator skills to attempt that, though getting the scale right will be fun. And you'll still have to source all the old bits and pieces.Either is do-able, but given the number of different boards you need to make all the modules you will want for a modular synth, I expect it will be more than you are willing to pay. Might be cheaper to just by one of the reissues commercially available from Moog. (Or a synthesizers.com system...)

The plastic sockets can be purchased with built-in decoupling capacitors for logic chips.To duplicate the assembly you show, you need to get the version with a metal carrier. The carrier is like a disposable IC with the pins on each leg. It keeps the bare pins aligned during soldering. Then remove the carrier and install the IC.John

content: Hi GaryI guess it comes down to how many parts per PCB you want to place.Vision is almost 'standard' for all the small machines now.All machines are capable of good accuracy if set up well.The difference comes down to the type of feeder.The "built in" tape feeders are cost effective, but you need to intervene more often.The cartridge feeders like Yamaha CL in the QiHe TVM920 or Charmhigh 930 are the pro feeders, they are reliable over thousands of parts. but you got to fork out $60 per 8mm tape feeder.All the machines will do pretty good loose parts and tray pickup.Something like a TVM802A or 802B are quite cost effective machines, but the simple feeders need more intervention - but that may not be an issue on small numbers of placements.So, when you jump to the bigger machines, you also need to buy feeders.something like this : (price including cartridge feeders)TVM802B : 4k (built in feeders)Neoden4 : 6.5k (built in feeders)Charmhigh930P4 : ~ 9k with yamaha feedersQihe TVM920 (bigger) ~ 10k with Yamaha feedersAs for software, the software with the Chinese machines is satisfactory at best. But certainly usable. OpenPNP support is being added to these machines.regards

content: Thanks... yeah, I know about the feeder issues. I've been following along here for a while.My main question is the vision one. You can buy a Charmhigh CHMT36 for about 3k shipped, and apart from vision and of course the type of feeder, it is pretty well specced... So for simple requirements as outlined, maybe?

Made several calls but open to other options.Relevant facts:* The first of several products will be an automated door opener with phone notifications via server and SMS.* Built from an ESP8266-based ESP-07S (FCC certified), 28BYJ-48 stepper motor, ULN2003 (probably) driver, and D alkaline batteries. This device connects to an Amazon AWS server via MQTT. There is a website (also likely hosted on AWS) for customer interaction with the device. Phone alerting via SMS, likely using a third-party service such as Twilio.* Payments received via PayPal.* I need $1M General Liability at least, would really like Errors & Omissions and Data Breach coverage as well.* I'm working alone at the start; no employees, no sub-contractors.* Operating as a Sole Proprietor to begin. (But will incorporate if that's preventing coverage.) Incorporation will indeed happen soon, but not on day one.* I live in Florida in the United States.* I'll be buying components from overseas. (But will consider buying domestic if that's preventing coverage.)* Less than $10k gross sales expected the first year.* Sold direct to the customer via the internet.

I am therefore looking at fitting an accurate controller so that it is a useful SMD oven. Has anyone any information if the ControLeo2 would be suitable for the T962A. A company called ESTechnical were providing a suitable controller however they are unable to supply the controllers since they had a fire at their premises.Phil.

content: I've built an oven with the ControlLeo2. I can vouch for its capability, and the results obtained. Essentially you need to adequately insulate the oven (ceramic fibre blanket works well) and have enough element power to do the job. I assume this has that. You have independent control for 2 sets of elements (say upper and lower) and another control for a booster element or a convection fan.

content: I'm not familiar with the T962A or its controller so I am commenting largely in ignorance. However note that the ControLeo2 uses an open-loop temperature control technique and only has 1 adjustable setting for reflow (without hacking the source code) - the target peak reflow temperature (unless I've missed recent updates to the code). It may be perfectly adequate for your needs, or you may find it lacking if the T962A's stock controller offers any kind of sophistication.ControLeo2 will run on an Arduino and it's easy enough to get one running to give it a trial - my DIY oven currently runs it on an Arduino clone, with a DFRobot style LCD/keypad for display and control, a Maxim SPI thermocouple adapter and a triac + opto-driver for the heater element control. Of course it's easy enough to use OTS Solid-State Relays with logic-level inputs for the element(s) control. To get that running just required adapting the code to the keyswitch input and the thermocouple adapter (from memory).What is it about the existing controller that leads you to call it inaccurate? I know I'm not overly happy with the current behaviour of my setup. I use a separate thermocouple-based temperature meter to compare with the ControLeo2 temperature, and the two are rarely in agreement. In particular with a reflow peak termperature setting of 212C the meter gets to a peak of 225C, while the ControLeo2 peaks at about 215C.

Toner transfer Laser Printer PCB without fusing / fixing - Page 1
Forum section: electronics / general

author_rank: Regular Contributor
timestamp: October 31, 2016, 12:37:26 pm
content: Picked up a discarded laserjet from the trash to use for toner transfer, but the fuser film sleeve was broken. Sleeves are replaceable, but doing a single repair is more expensive than just buying a working second hand printer at the thrift shop. I also hear fuser repairs often turn out poorly.But, I hate throwing stuff away if there is any chance of repairing them.The printer actually prints ok in the sense that text comes out fine on the paper, it is just the paper that gets stuck in the fuser, and of course the fuser doesn't heat up properly so the toner wipes off the paper.But since you are supposed to iron the paper onto your copper board, does it really need to be fused to the paper?It will take quite a bit of destructive modification of the printer to make this work, that is why I'm asking you guys first instead of just trying it myself.By the way, I'm already aware that it is better and likely cheaper to just buy boards from a proper fab. I'm want to use this printer just for the sake of recycling.

content: No it doesn't, assuming the static adhesion is sufficent to hold it in place while you fuse it to the pcb.Indeed, direct-to-pcb toner printer mods don't typically use the fuser, the toner is deposited onto the pcb and fixed (fused) later by baking or acetone vapor bath.

It was around $100.00 when I bought it.I have messed with magazine paper, photo paper ad infinitum, PnP blue. And I would suggest you try some Pulsar toner transfer paper. Easiest, best results, and it does not damage the printer. Mouser carries it. Forget the foil overlay and other stuff, and just get the dextrin coated transfer paper, IMO.

These are not cheap machines, probably the starting price will be around 10 000 - 15 000 euro for their basic models.There are also Chinese knock-offs for some of the ERSA models. Chinese IR stations also exist and are much cheaper, but not sure on the quality.

The whole design is not pleasing and too manual.Is there any other professional grade other than ersa?For the ersa have you guys tested any? We are wondering between the HR600 and the HR550.We need this machine for two purposes:First: a rework of a QFN or BGAsecond: a easy pick and place, for delicate components like BGA for too small productions to program the big automatic pick & place machine.

content: I have worked only with IR/PL550 model and I cannot say anything bad about it - it even has a cooling side that you move the board once done, which not many other machines have (I actually do not know of any other that has this option). I think you will not go wrong with ERSA their workstations and soldering equipment are work horses. But do test first and see if it fits your needs.One complain I have for the HR600 model - at such a price point and a product that is clearly aiming for the 'top of range' type products, I think an addition of automatic solder pad cleaning nozzle/suction mechanism would complete the machine, something similar to the function of AirVac ONYX29.
