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.
  • Professional Rework: Failed components are carefully desoldered and replaced by our experienced technicians using modern rework stations.
  • 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.

Diagnostic Testing

After repair, the unit is connected to a dedicated test rig where we simulate real-world inputs and verify that outputs match published specifications. Our functional analysis confirms spec-level operation.
