Preheating is critical in Vapor Phase Soldering. One trick that is done is to use the "soft vapor" area just above the soldering vapor, some machines can pause just before going into the soldering vapor. Using that pause above the vapor to continue

In general two step temperature reflow process requires minimum 40 deg C delta to be sucessful. We are not using vapor phase soldering but we have similar situation when we change to SAC lead free solder for PCB component population and secondary swe

Currently we are using a 2 step vapor soldering process to manufacture our std. lead soldered parts. The first step was done with a ls240 vapor fluid and the second was done with a ls200 fluid. Using a 221 deg C sn95/Ag5 solder for the first step a

Vapor phase soldering systems by Asscon are characterized by special designed heating modules. The thermal mass of the heating modules is designed so that a completely delay-less and direct regulation of the heat/flow/energy transfer to the soldering

You wouldn't have a very good profile if you went straight from room temp to vapor temp (_-). The chamber should preheat the board before using vapor to melt the solder.

Perhaps a little hard to find but is there anyone who uses a vapor phase process to solder populated card with BGAs. I am interested in the success rate of such a process. It is obvious that the throughput is reduce vs a convection oven but still thi

Steve, If you can get me your snail-mail address, I will send you some latest information. We actually have a totally new system called Delta 5. It is Condensation Soldering rather than Vapour phase, the difference being that we solder in an air ti

I am in the mid-Atlantic US. I need to solder PCB's to a large copper heatsink. Does anyone know of local (or not so local) ECM's with vapor phase capabilities? How about induction? Thanks!
