Trace repair for PCBs in blockchain mining equipment involves fixing broken or damaged conductive pathways—known as traces—that connect different components on the circuit board. This intricate process requires identifying the break or damage in the copper trace, then carefully restoring the connection using soldering techniques, conductive ink, or wire bridges. Proper trace repair is essential to reestablish electrical continuity, ensure signal flow across the board, and maintain the reliable functioning of the mining equipment, preventing performance issues and potential damage to other components.
