1) why is No-clean (NC) the preferred process, for BGA mounting by SMT? Probably the same reason NC is the preferred process for mounting non-area array SMT components. 2) why is water-soluble (WS) not a hot choice? There�s not reason not to use

All the points raised so far are correct. Only use QFPs if rearly pushed as the yield on your process will suffer. I have wave soldered parts down to 0.020" in nitrogen with OK results but the pads and drainage pads need to be worked on. Another r

Im with Pete, Zero defects. We have high defect rate for many reasons. No line tech, operators set up and run then when QA reports defects engneers are called. Not to make people mad but our process engneers are lacking practical experance to fix pro

Hey Pat: My responses are: 1. Does anyone have experience with the shelf life on immersion white tin? If so, how long can the boards be stored without adversely affecting solderability. I've heard one year. No, we don�t, because we turn boards fa

Hexacon sells the LevChek, it is a special tempered glass plate for checking a wave solder machine. They make different sizes, so you can get one that is close to the maximum width of your wave. They also have grid lines etched on them so you watch i

Pat, Try to run a glass plate (yeah I've used these before too), keep your wave pump speed the same, and slow down your conveyor speed. You will find the actual contact between molten solder and the 0.5" grids to be LESS vs. a faster conveyor speed
