We are looking for solutions for the random occurrences of the solder
mask flaking. We are experiencing the flaking from several board
manufacturers and several different masks, LPI and Dry Film. The
flaking is occurring during the wave solder process.
We use a no-clean flux and spray fluxer. We run at 4.5 ft/min., with
a top side temperature at 210F, with five feet of bottom side IR
preheat and 2 feet top side. Our incoming inspection does not test to
IPC840C, does anyone?
Thank you,
Jon Silvernail
