hi all, i have purchased an used vapor phase and i can't make a constant profile. the profiles depend on the time i wait between two batch... the only difference that i include is the chamber temperature i don't understand why the chamber temperat

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.

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.

We do the same as LarryD. All the profilers I have seen that have thermal jackets deemed capable of going through and helping the logger survive the VP process have a lot of mass. This mass will affect the profile considerably.

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

What equipment do you have? As well as the comments from others, another major influencing factor can be the residual heat in your PCB carrier. It takes more heat energy to warm a cold carrier than if it is already hot from the last cycle run. This

| 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 t
