No matter in selective soldering or wave soldering process, higher pot temperature and longer wetting time can increase IMC thickness and joint strength(reliability), but as Daivf said, you need to care if the DIP component and bare PCB was damaged b

Maybe increased barrel fill? Raising pot temps slightly seems to increase barrel fill at selective solder, something we battle with.

Is this for a Selective Solder? If so what size nozzle do you run. I run at 315 C most of the time. You can speed up your process time and still achieve good solder fill.

Selective Soldering Frames can pull large amounts of heat from the solder wave at the point of contact, effectively lowering the temperature of the solder at the solder joint. You should confirm the temperature of the solder joints by running a therm

I was actually thinking about the wave soldering machine.

I'm sure this isn't the same situation, but we did have a selective solder machine with crazy dross and solder ball build up. Turns out the operator switched the low pressure nitrogen line used for solder level and the high pressure nitrogen line fo

In a previous lifetime, we had a selective solder machine where I would see solder splashes in the roof of it. I thought someone might have been putting the solder extremely high. But when it was melting there would be bubbles that burst. The manufac

We use both types in house. We started with a board moving over the pot, slowly moved on to Jade machines and eventually Synchrodex. Like you mentioned without palletizing you'll have component movements during the cylce and most likely won't have th

I use a two machines from EBSO, Germany. It's a machines with PCB carrier, so, solder pot is fixed. I'm fully satisfied with this equipment, but I use only wettable nozzles. If you would like to buy a new machine, not in used condition, EBSO will be

Thanks for all the remarks. I am tending toward the move the pot method. I am concerned about parts tilting from square if moved or held at an angle. I won't need to deal with board pallets, board clamp mechanisms, etc. Plus I found the moving board
