Hello !! I have a problem with my wave solder oven, in one of the products we made has connectors on one side of the pcb and in the other one has SMT components the process is kinda tricky on the SMT components we use an adhesive and put to the refl

We have a Seho wave soldering machine and cannot seem to get rid of dross that is being generated within the solder pot, and is being pumped out in the wave. It is not the same kind of dross that forms on the surface of the solder pot(this is very m

Robert: Several points: 1 Dross is a mixture of various things with no "fixed" composition: � The obvious things are metal oxides mixed with metal and this can vary in color with temperature and composition - remember some intermetallic oxides form

Hello all, I have a problem with the wave 6622c . The temperature of solder pot and preaheating zones 1 and 2 is not increasing. the strange thing is that the machine is not display no error. Can you help me with some advices?? regards

Florin, Not sure if this will be helpful or not, but I have completed a couple of pot height retrofits for these waves and I seemed to remember that one of my clients spilled some solder and shorted out the 24vdc power supply. I am pretty sure this

hi, This is moisture problem, I think.I have similar problem.You must try to bake PCBs.I bake our PCBs in solder wave mashine , under solder pot.There T is about 80*C - after 6-8h the PCB is dry regards

It is a lead free process with sac305. We use goldfinish FR4 boards. Preheat is between 110 and 115 degrees. I am sure it is a moisture problem because longer stored boards have more blowholes. What is the maxium period to store the boards without

are you sure it isnt down to an hygroscopic contaminant causing the problem.I've only ever seen it once or twice in gold,really quite unusual.Its not too much gold brightner or similar residue.If it can be cleaned off then it shouldnt be there so it

I have problems with blowholes during the wave soldering process. I already find out that the stock time between reflow and wave is the most important. The longer the boards are in stock the more blowholes we have. We don't have a climat controlled
