I have printed and placed similar devices in high volume with exactly this spec for a couple of years with no problems, are you using laser cut stencils and what type of solder paste are you using? and what is the end use of the product as it may nee

I'm a new guy in this field. I have a question about solder paste process. Is there any effect to the solderbility if we do a lot of contact to copper pad without using any insulation ( direct to the finger ). Where can i get information about smt pr

Solder flux and solder paste deposition is a standard step during the chip attach and sphere attach portions of BGA and CSP assembly. A technique called ultra-violet fluorescence intensity mapping (UV FIM) has been introduced that allows flux measure

Thomas, Dave is right - we had a similar coplanarity problem on some BGAs which we solved simply by over printing - no step required by nearly 2 x what happens is that the paste hight will grow as the paste reflows confined by the pad drop me line a

I am trying to find out, what possibilities I have, to print solder paste on a board, when the task is to have 120 Microns thickness for the biggest part of the board (85% of the real estate), and then have 250 Microns of thickness on the remaining
