Circuit Frames have a bond strength equal to the original, can be used on loaded circuit boards, and the bond time is just 30 seconds. Our replacement Circuit Frames have a dry-film adhesive backing to make the repair process quick and neat.

You may be inclined to re-heat and reflow the solder using a little extra flux. It's reasonable to think this will work but it can be deflating when it is not effective. In a desperate attempt to correct the defect, the process may ...
