I am hand soldering a flip-flop 14 pin IC to my circuit board. (Part # CD4013BE). The holes in the circuit board are .033". The circuit functions fine for about 10 minutes and then quits. I probed the pins and get a ground and Vcc at the pin. If I reheat all of the solder joints, the circuit begins to work again....but, after 10 minutes it stops. Any ideas?.....
