Davef, thanks for inputs. I think your correct, we have since obtained some ionic analysis and sure enough there is relatively high chlorides on the bare pcbs. The toluene is controlled within dip tank / drying system, almost no exposure to workers.

Hi All; Anybody here have experience in AVR80 BA DS65 CC process? I have an issue with the curing process at 28 degC RT. Can somebody recommend how to accelarate the curing without IR oven? thanks

Why not just pick up something like an old Camalot 1414 and use that? Then all the work other than rigging up a valve is already done. 1414s go for a couple or five grand in workable condition, especially without a pump.

Thanks Dave, The problem is on all 0805. Do you think it could be a reaction with the flux from the wave or the one in the paste. Do you think the problem is the viscosity of the coating. SPEC = Viscosity 150cP nominal ASTM D-1384. I ask you all

We're not familiar with your DYMAX #984-LVUF. The problem is not with your conformal coating. The problem is with your 0805 [and not all of 0805, probably just those from a specific supplier]. This lack of coverage of components is called dewetting

Terry The SCC3 product is a vinyl modified silicone. It is less able to perform at low temps as it becomes brittle. It is not easy to repair because it is essentially silicone. It is not a qualified material to the MIL-I-46058 Spec. Are you sure yo
