Rebuild Steps

Each YASKAWA SGDA-04AS control unit is diagnosed using schematics and specialized test equipment to find the root cause of the failure before any repair work begins.

  • Trace and Signal Analysis: We analyze the circuit board for broken traces or weak signals that could cause intermittent faults.
  • Component-Level Diagnostics: We test individual resistors, capacitors, and ICs to pinpoint the exact source of the problem.
  • 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.
