We are not doing this right at the moment but I have done it with great success. Of cource it depends on your pad layout we have a 20 mil gap in between pads, we printed at 10 mil wide with a 5mil stencil. I will try to find the glue we used, I kno

Russ, We can not use a wave pallet, already went that route. We have parts next to the thru-hole pins and between thru-hole pins. I am going to try an experiment in the next day or so with solder mask. I plan to solder SMT parts on the back of se

Well, I have not had a chance to run my experiment yet. I hope to have the wave solder machine to myself on Friday morning. I will let you know. I am hopefull from what you and the others have said that it will work and we can reduce our touch lab

I would suggest that you contact your local contract manufacturers and see if they want some "free" labour for a month or so. There may be difficulties with insurance etc - maybe your HR dept could help there. Try and find one with a few different li

I have seen BEC holes drilled wrong also. On a couple of products We run, We insert a Pem Nut. The insertion hole is too large for BEC to read. So We have the board house drill a small hole for each array, circuit. If these smaller holes are drilled

We don't have any automated machines (UIC) that insert anything into holes larger than our terminals, so about 0.050" is as big a hole we ever have to use before we've plugged them with something. Since we also do a fair amount of Man-U-Sert (yes, yo

If you already have trouble with two set commands, you will get many more when you add 3 more. Maintenance MUST learn to align the machines correctly. The BEC scenerio you describe proves that the alignment is wrong. The table can be adjusted for

Another question about Set Command Variables. We use fixed dimension, multiple window PCBs in all of our UIC machines. It is often required that we use the rotary table to populate the entire panel, but this means that for each rotation, either the w

You want approximately 5 particles minimum across the smallest aperture. So in the case of a 0.8mm device, we use .017" pads with a round 0.020" aperture on a 6 thou thick stencil foils. Here, 0.020" diameter equals 0.50mm. This gives us 0.50/5=10

can anyone provide me with information on the operation of the Zevatech Print-MAT 220? Its a pretty basic machine, but my question relates directly to the squeegee blade setup and leveling the blades to the stencil. If you level the blades together
