Rebuild Steps

Our repair process begins with a full diagnostic evaluation of the circuit board. Technicians trace signals and test individual components to isolate the failure point, from faulty capacitors to failing ICs.

  • Sourced Components: Replacement parts are sourced from our inventory or reliable suppliers for a quality repair.
  • Trace and Signal Analysis: We analyze the circuit board for broken traces or weak signals that could cause intermittent faults.
  • Static-Safe Environment: All work is performed in an ESD-safe environment to protect sensitive electronic components.
  • Professional Rework: Failed components are carefully desoldered and replaced by our experienced technicians using modern rework stations.

Hydraulic Testing Process

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 spec-level operation.
