Yes, but I have seen designs where the whole row > of leads has no mask(which is also a NSMD) Apparently I might have to do just that for some parts. We have a few parts with 0.2 mm pads at 0.35 mm pitch. Our PCB shop says that they need at least

I worked with a few BGA rework stations and also had the chance to see several demos on different brands. THe good ones that can really do it are equipped with camera, infrared under the board, different nozzles and a hot air comming from the head(di

I have a few questions: Why are you unable to panelize an aluminum board? We run aluminum boards all the time utilizing both V-Score and Routed designs. Panelization aside, what are the issues that you run into at printing? Are you trying to print

You might look at "Tacsil". It's a product we've used over the years for stuff like this. It's basically a sheet of material that can be cut into any shape with scissors or X-acto that's sticky on both sides. It can go thru reflow a bunch of times

Don't know if you can do it on a MyData, but I have found that I lower the rate of failed pickups on our machine by altering the placement order of devices. Specifically insisting it does not attempt to pick sequential parts from the same lane. Of co

My job is manufacture the custom PCB boards, as I know, most of our customers use Eagle. It's really common use. You can dig internet for more information about this tool. Or you can try frizing, EASYPC,KICAD or other tools. You can check which one i

I do a lot of prototyping, but I also do production boards. I produce 2000-5000 boards a month for an in house smt process. I feel this will increase do to the fact that our engineers are designing more with surface mount rather than through hole. S

We made the same change a year ago, from foam to spray fluxer. One of the reasons we changed, to keep the acid number within specs (foam fluxing) we had to measure once or twice a day and add DI water to make up for evaporation, all along not able to

So far we have tried diferent date codes, solder pastes and PCBA models (same component used in different projects). We have also sent some components for plating analysis and we are waiting the LAB feedback. Additionally, we have tried components wi
