I have experience in this. My company offers Lead free SMT and Wave soldering. I have processed ImSn, ImAg, Enig, OSP in both smt and wave. Yes, silver leaching will occur. Yes, copper leaching will occur. High tin content solders disolve everyt

Can anyone comment on inspection criteria for PIH applications. I'm of the opinion that the inspection criteria used for wave soldered joints should be used for PIH. Some colleagues believe that a bottom side fillet is not necessary since the solde

How big are the boards? I havn't done a lot with wave solder and I'm just wondering, how much solder these boards would use. Also I seem to recall being told that a thin layer of dross helps prevent more dross from forming. Of course this would not b

I don't know if your pot can be cleaned out, but even if it can, lead free solder will almost certainly eat through your pot. There's plenty of information on this site about this subject, I recommend you try searching for something like "lead free

Hello all, We have resently run across a solder joint from a through hole part that looks to have a wrinkle effect (star look) from the wave? No pattern it just happens here and there, and some of the joints on the same row look smooth and good. Any

I have been using sn100c for over a year now on our wave solder process and I am plenty satisfied so far. The secret for success with this alloy is to have your solder pot near 270 celsius and your dwell time has to be near 4 sec and your temperature

I have done a few studies on this issue here. As a result we have increased hole diameter on heavily ground planed pins to a min of .015" over the lead diameter as well as preheating the PCB when hand soldering. I have also had to order the upper pre

the problem I had with pump was that turbine intake was eached by alloy. when I repaired intake, it was a irregular hole about 32mm in diameter, mechanics welded piece of plate with a 24mm hole (that was a factory size) we had to reduce pump speed fr

Zac, how about the following: 1. Thermal profile for the flux 2. Is your wave leveled? - If you see better joints on one side, you should probably level the machine 3. Just for elimination, do you have another flux, that you could spray on a board
