May be you need to look for different material for your jig so that the jig is thinner and carry less heat. Also you probably need to build more jig to allow cool off time before use it again.

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
