thk you very much for your fast answers. And yes, I am suspecting the same things also. The problem is to convince the PCB supplier that is his fault. A big fight all the time. SO, i will double check everything you said, and I willl come back with r

Does anyone know where to find information for wave temp profiling? pzohbon

Hey all! The wave solder warrior is back. I have found a flux which leave almost no residue (the least yet), but because of its super low solids content I absolutely cannot get topside fillets. The multi-layer, two sided board is on a pallet w

It is probably due to the solder mask being undercured and is porous alowing the flux to be absorbed which boils when it hits the solder wave that kills the adhesion. You should be seeing this only over copper traces/tracks. Reduce flux volume and in

Thanks Nicoleta It is nice to hear the problem is solved and this is a massive problem in the industry especially for Lead Free. It is easy for a supplier who doesn't understand to blame incompatibility just a quick way out but doesn't fix anything

A little more information on your current wavesoldering process would be helpful in helping you. Information like what kind of flux your are using,how you are applying the flux,what preheat temps you are using,and your conveyor speed. Without knowing

what type of preheater does the novastar use and what temp. is it set on? I am also use to a hollis wave solder machine. Old and crude but works great.

Thank you for support. As i promised you, I am coming back with the results. The SM used was Probimer 77 with Kester 979 flux. The supplier says that there is an incompatibility and we have changed the flux with IF2009M. Same problem! They have chan

I am new to wave soldering. Any information is greatly welcomed. Here is the problem. After soldering the boards they have a film on the bottom of them and sometimes a white powder looking substance. I have tried decreasing the amount of flux on

we do that and there's a variation on the solder temp. sometimes around 10 degrees, we have 2 solder pallets that are run in intervals of roughly 3 1/2 minutes a part (the time that take the operator to put all 3 terminals in a 42 pcbs per board, and
