B2B & Industrial Electronic Diagnostic & Board-Level Repair

At Micro Fix (Lynnwood Glen, Pretoria), we offer specialized component-level repair and advanced diagnostic services for commercial, solar, automotive, and heavy-industrial electronics. Instead of replacing expensive, hard-to-source whole assemblies or waiting weeks for overseas replacements, our bench technicians isolate short circuits, blown power stages, and degraded micro-components directly on the PCB.


Step 1: Submit Your Industrial Equipment

We handle both standalone printed circuit boards (PCBs) removed from host equipment and complete specialized power conversion or control units.


Equipment Categories We Service:

  • Solar & Renewable Power Electronics: Standalone hybrid and pure sine wave solar inverters, mobile inverter trolleys/power stations, and high-current Solar Battery Management Systems (BMS).

  • Automotive Electronics: Vehicle Engine Control Units (ECUs), instrument clusters, eBike/eScooter mainboards, and motor/speed controllers.

  • Commercial & Fitness Electronics: Commercial treadmill/fitness equipment drive boards, solar geyser, HVAC, and industrial motor controller boards.

  • Heavy Industrial & Plant Machinery PCBs: Specialized engineering, measurement, and manufacturing line PCBs, high-voltage power conversion boards, and standalone host equipment electronics.


Step 2: Thorough Circuit-Level Bench Assessment

Every submission undergoes a thorough physical inspection, high-voltage/signal rail tracing, logic testing, and component breakdown analysis under controlled bench conditions.

Assessment Fee Structure:

  • Upfront Diagnostic Desk Fee: Covers technical disassembly, circuit schematic tracing, signal testing, and component sourcing required to issue an accurate written repair quotation.

  • Heavy-Industrial & B2B Assessment Terms: B2B, commercial, and industrial equipment require extensive bench time, high-voltage testing protocols, and specialized trace analysis. In accordance with South African contract law and CPA provisions for juristic entities, assessment fees for specialized heavy-industrial units are non-creditable standalone fees that reflect the independent technical diagnostic services rendered.


Step 3: Component-Level Repair & Bench Testing

Once your quotation is formally approved, our technicians perform targeted micro-soldering and circuit repairs:

  • Targeted Fault Resolution: Replacing shorted MOSFETs, blown power stages, damaged CAN-bus transceivers, burnt traces, and faulty logic ICs.

  • Controlled Bench Stress Testing: Serviced boards undergo testing using bench power supplies and simulated loads to verify signal integrity and power rails before release.


Step 4: Quality Sign-Off & Clear Operational Terms

  • Scope of Service & Focus: Micro Fix specializes strictly in component-level electronic repair of the specific PCB or control unit submitted to our bench.

  • Safe Protocols: Final installation, wiring harness checks, system re-commissioning, and vehicle/host machine safety tests remain the responsibility of your certified installer, auto electrician, or plant engineer.

  • Compliant & Transparent: Non-VAT vendor (all final totals quoted are zero VAT). Serviced equipment uncollected after 60 days post-quotation is managed per South African common law storage terms.
