One thing you can try, is that since you have to return the jigs anyway to the beginning of the wave solder process, you might want to use a conveyor with fans on top so that the fans will cool off the pallets as they go through the conveyor.

My jigs are quite thick (~0.5") in order to mask off the high filter components on the solder side. As a result the jigs get very hot after soldering and takes long time to cool down to be feed back to the cycle. It also affects my profiling, throughput, and seems to create more dross than usual. Any comment or advice? Rgds, Peter
