Do you have any pointers concerning the oven setup and profile if you are soldering a module with bottom connections and gold pads to a pwb with an OSB finish? The solder paste is SnPb, no-clean. The paste mfgr. recommended profile produces voiding

Can anyone recommend software for work instructions? I am using the software with gerbers for through hole and SMT. I have tried Unisoft's software and found it to be difficult to use with gerbers. Is there software that will color code the location
