We have encountered what appears to be mask discoloration after wave soldering. The areas of concern coincide with the areas that were exposed selectively by fixtures during wave soldering, dominated by one date code of PCB with a slightly different

Peter are you having fun with solder masks erwat? We saw this years ago with LPI solder masks. It shows occasionally with other masks. We agree with Russ. If nothing [eg, alcohol, flux thinner, acetonitrile, or water] dissolves the haze, then it

I usually see this with mask that is not fully cured from the PCB shop. This probably agrees with the baking statement that you made.

We have experienced a problem with tin leaching or discoloration of lead terminals on random parts on solder side of a paste/paste operation. The profile has been used on previous production runs and there doesn't appear to be any heat damage to othe

we are manufacturer of molded type transformer and we soldered are units using wave soldering machine and then we washed the units to remove flux residue. what materials or any process for us to eliminate the process of washing after wave soldering.

Hello, thanks to everyone that reply to my previous question. I have another request: is it possible to solder polyester capacitors (case 2220) with wave soldering process? Thanks! Regards, Stefano

Only if it has exposed ends on the end.

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

we have some rebuilt wave soldering systems in stock ready to be shipped. epk-ii smt with lambda wave, chip wave ,omega wave. 4 preheaters,jacking stand roll out computer control. machine is in a great shape. another machin upk15f with 6 preheaters
