Disassembly and Rebuild Procedure

We specialize in component-level repair for the FANUC 3D6978. Each unit undergoes inspection where we identify and replace failed electronic parts before functional testing.

  • Trace and Signal Analysis: We analyze the circuit board for broken traces or weak signals that could cause intermittent faults.
  • Professional Rework: Failed components are carefully desoldered and replaced by our experienced technicians using modern rework stations.
  • Static-Safe Environment: All work is performed in an ESD-safe environment to protect sensitive electronic components.
  • Component-Level Diagnostics: We test individual resistors, capacitors, and ICs to pinpoint the exact source of the problem.

Leak and Performance Testing

Each repaired board is burn-tested under load for an extended period to catch intermittent faults that short tests would miss. Our diagnostic analysis confirms proper functionality.
