| Hi Kelly, | A couple of questions first. what type of BGA are these components? CBGA, PBGA, TBGA, etc. What is your aperture diameter on your stencil and what stencil thickness are you using? I think I can be of more help once I know the answer

| We are currently investigating alternatives to HASL for circuit boards with 20 mil pitch smt pads and below. If you have experience with this product or simular immersion tin products with respect to manufacturing or assembly I am very interested

I know that Contact says it will do it but I am having difficulties placing a 20 mil TSOP with consistant results so I don't really trust how well it will be able to place a 15 mil QFP. The part is going to be used on every board we produce, average

I am working with fine pitch components (15-20 mil) and having soldering problems and would appreciate some opinions. 1) How much of an effect does pad size have on bridging? 2) How much of an effect does solder paste grain size have? What is the re

Does anyone reliably place 20 mil pitch QFPs with a zevetech 570laser upgraded to 575 with a VCS camera vision system? Different spec sheets seem to conflict with each other, and even the people at juki have given me different specs. If anyone has an

Dave is correct in that the Zevatech is actually a Juki. Made by the Japanese Juki and labeled by the Swiss Zevatech. The PM 575 is somewhat vintage. I believe it may be all mechanical component centering. It may be OK for the 20mil fine pitch but ma

I read the messsages but I did not meet my need. We currently have Excellon and ATI machines. They work ok for thick boards (40 mils and above) but for thin, small boards (15-20 mils and USB side dimension), it did not fulfill our needs. So, pleas
