Has anyone heard whether the elevation of a plant can effect solder joint formation? One plant at sea level, one at 7,000 feet elevation... same equipment and profiles, big voiding defects at higher elevation. I did a search and found no similar post

I am having problems with voids in our soldering process. I believe it to be the fact that we use a no clean flux without control on how the boards are handled (gloves, procedures, etc.) Does anyone have suggestions on the appropriate place to start?

Are the voids in the balls of a BGA? Are you verifying this through x-ray if they are? some voids depending on size and location are some what accepted. Solder paste type? Solder paste date code? Humidity high? PCB's been stored in a truck trailer?

Are your voids looking like blow holes also? Is this only occurring on the solder joints of the Thru Hole components and Via's? Or does this happen on SMD pads? My experience is that we have seen this but only with some of our older PCB's which are

Two things: 1 Go to IPC and buy "TP-1115 - Selection & Implementation Strategy for A Low-Residue No-Clean Process - Provides direction to electronics manufacturers interested in adopting low residue (LR) assembly technology. It addresses the concern

More and more pople are seeing voids in solder connections other than BGA balls than ever before. Thats because they never looked [never had the means to look] before. Now, they can't stand it and, like that zit that their mother told them not to m
