Hi, It sounds like your a little new at profiling, and can be difficult to do well. We purchased a KIC profiler that has software that will take your profile data and tell you the best oven temperature settings and conveyer speed to use. You need

Good answer slthomas! This has got to be the biggest misconception out there. To perform SPC on a wave process you must first perfrom DOE to determine the critical parameters and or control limits. For example you will need temp reading devices tha

Dave, Answers to your questions: * From your pictures, the white residue appears to be only on the solder mask. Is that correct? If not, what is the location [eg, solder, nonsolder/nonmask areas] of the residue that doesn't show well in the pictur

What kind of problems/defects/process indicators are you having? It is likely that you will have to bite the bullet and get a thermal profiling mole to prove that your selected profiles are subjecting parts to the correct tempertures per part specs.

I think where the fuzzy thinking starts is by calling the recipe's; profiles. Or maybe I"m being too fussy. Idealy you want every solder joint to have the same thermal "profile" (not recipe). That is the temperature over time is best if identical fo

bobpan, thanks for the reply. I currently have a Quad 100 with no vision, well it had vision but is blind now and the vision system is not supported. Anyway, I use it for my own production. I can leave it set up for my product runs. Technology ch

We are experiencing fracture problems with 0805 X7R capacitors. The capacitors seem to fail in tension; during hot-air rework they come apart in two pieces with the fracture near the metallization end. Only X7R SMT components are affected, C0G and Y

To recap: 1) The machines use laser centering, not mech jaw centering. 2) The X7Rs are scattered on the board, center and edges. Improper de-panelization would favor damaging the parts near the edges of the board; this is not the case. 3) Both ROH

Alpha-numeric suck! Just kidding. We had a guy that was in charge of our waves who said the same thing. Never two sure what he meant by that. I've been runnning wave solder for 12 years and them Gels seem to get rid of the broken parts at wave. N

I have Immersion Ag and Immersion Sn LF boards that were waved using SAC305 alloy. I have a lot of tears/shrink voids in the waved connections. I am aware that SAC305 in wave has a propensity of shrink tears/voids due to the non eutectic property of
