Hello, I am new to the SMT area and I need to know what a "good" vapor phase reflow profile should look like. The fluids we are using have a BP of 45 C and 219 C. Thanks,

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

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

We use the same profiler for convection and VP. For VP you just have to be very careful as the thermocouple wires must travel through the machine so cannot get "snagged" on anything as they go in or come out.

I think it is a good idea to "waste" money on this analysis. Especially if you phase in a SAC wave alloy. Silver is not toxicity free....and lead free waves can dross 3 to 5 times faster than SnPb alloys. This produces a greater potential for airb

nifhail, In a nutshell: Vapor-phase reflow is a process that uses a fluid with a selected boiling point. As condensation of the hot vapor occurs on a cool assembly the assembly's temperature is rapidly raised to match the temperature of the vapor.

Expanding on a previous poster's comments ... Vapor Phase Soldering. A solder reflow technology that uses a heated solvent to melt the solder. Buried deep in the recesses of the SMTnet Library is �Terms & Definitions�. We started using vapor phas

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
