Krishna, Did you say "One" big through hole component? Why not hand solder the Big One? Components wandering off from their designated spots will be a history. If the Big One is a connector with lots of pins, selective soldering is a better option. Matthew Park >>> Krishna Kalyan <[log in to unmask]> January 6, 1998 1:59 pm >>> Tech Netters : Hello all. Thanks for all your suggestions. My problem is not as simple as it sounds because I have a (BIG) through hole component that is inserted on the top side which needs to be soldered along with other SMCs. So I need to have high enough a temperature on the bottom side to solder this BIG component while keeping my other problem-prone SMC on the bottom side intact !
