Good to know there are a few smart people left in this industry like Darby. I love how everyone assumes the original poster was only talking solder paste. We use screen printers for five different materials. Some of which we triple print by design

Can anyone tell me the differences between the CP6-4000 and the CP643? Is the CP643 able to place a wider component range? Does the CP643 have some sort of vision system while the CP6-4000 doesn't? If anyone has the Fuji Specs on the CP643 and could

We did numerous testing some years ago on matte, gloss and semigloss and found after chemical extraction of the PCB and IR analysis the only difference was the actual cure of the resist. The more plasticizers released the worse the balling If you use

We all know that Engineers are human and consequently may make errors when creating pick and place programs. (e.g. program a wrong part number for a given reference designator) Usually that is easy to detect since the wrong component is a differnt p

We do like Chunks says only a little bit different. Our stencil supplier e-mails us a "confirmation PDF" before processing any order. If it's a simple board, I just make sure all the apertures are there by comparing to board. If it's got a ton of

Get the ionic specs from your flux manufacturer, and show it to the designer. No-clean flux/solder is supposed to be low to minimal in ionic contamination, which allow the whole no-clean thing. If he needs further proof, you can have the board io
