9. Connections To repair a defective copper pattern at IC connections use the following procedure to install a jumper wire on the copper pattern side of the circuit board Use this technique only on IC connections 1 Carefully remove the damaged copper pattern with a sharp knife Remove only as much copper as absolutely necessary 2 carefully scratch away the solder resist and acrylic coating if used from the end of the remaining copper pattern 3 Bend a small U in one end of a small gauge jumper wire and carefully crimp it around the IC pin Solder the IC connection 4 Route the jumper wire along the path of the out away copper pattern and let it overlap the previously scraped end of the good copper pattern Solder the overlapped area and clip off any excess jumper wire At Other Connections Use the following technique to repair the defective copper pattern at connections other than IC Pins This technique involves the installation of a jumper wire on the component side of the circuit board 1 Remove the defective copper pattern with a sharp knife Remove at least 1 4 inch of copper to ensure that a hazardous condition will not exist if the jumper wire opens 2 Trace along the copper pattern from both sides of the pattern break and locate the nearest component that is directly connected to the affected copper pattern 3 Connect insulated 20 gauge jumper wire from the lead of the nearest component on one side of the
