Trace Repair (Jumper Wire)

Category: infrastructure

The delicate micro-soldering process of running a fine copper wire to bridge a broken electrical pathway on a circuit board.

Motherboard traces can be severed by physical scratches, battery acid leaks, or high-amperage burnouts. Technicians use a scalpel under a microscope to scrape away the top protective solder mask layer, exposure the raw copper, and solder an insulated enamel wire to restore connectivity.

Common Examples

• We executed a micro-scale trace repair using a 0.02mm jumper wire to restore the severed data track leading to the BIOS chip.
• Once the jumper wire is verified, it is sealed into place using a UV-curable solder mask resin to prevent physical movement shorts.
