Just curious what effect pinholes and solder voids can have on solder joints that have high current passing thru them. Also could moisture from steam sterilization (autoclaving) get inside a said solder joint and then outgas during high current, and/

Can anyone please help me locate details on maximum allowable temperatures of components when passing through a reflow oven. I think I want the thermal profile for the part, or a source or standard which will allow me to check if I can safely reflo
