Dear Bruce, We had the same problem in the same condition. Every compnent and the PCB (OSP) has changed as lead-free and we need to solder them with SnPb. For solution we have increased the flux amount applied on PCB and the pre heat zone temper

I do not know which specific flux you are using, but here are some general guidelines. If your wave soldering machine uses a foam fluxer, then there are foaming agents in the flux. Under �normal� conditions, the volatiles (including the foaming age

Foam fluxer, ouch!! That hurts. How about this? * Make a sheet metal box to cover your preheaters. [If your boss is really cheap, make a 'box' with 1/2" chicken wire and cover it with aluminum foil.] * Prebake the blank out of the boards, bag the

Hi Hope a few others give you applicable experience to your question. I never had a real long shut down, yet have experienced short shut down problems. I would run it in the best cleaner you have in your shop before you shut down for a long spell,

We are a small CM doing mostly prototype and small production runs SMT and PTH. We have an old Hollis machine works well when we need it. The foam level does not come up to the board level, even with the air cranked up full. We are using a synthetic

We used an air knife using foam fluxer and no clean flux to remove excessive flux from the boards for a better look afterwards. A secondary effect might be that the flux is forced into the vias giving you better results on the top. If you feel a need
