Overview

Service introduction

Production-machine boards fail through degraded components, damaged tracks, worn connectors and stressed solder joints. Component-level repair aims to restore the original board, which can help when a replacement is unavailable, discontinued or on a long lead time.

We diagnose the fault, replace failed components, restore damaged tracks, sockets and connectors, and carry out the checks appropriate to the board before handover. Switching power supplies, machine power boards, UPS and charger electronics are handled in the same way.

Technical capabilities

  • Component-level diagnosis of control, I/O and CPU boards
  • Industrial computer motherboard repair
  • Replacement of capacitors, fuses, MOSFETs, transistors, regulators, diodes and ICs
  • PCB track, solder-joint, IC-socket and connector restoration
  • Backup-battery replacement and board cleaning
  • Switching power supply, UPS and charger electronics repair with output or switching checks where applicable

The equipment behind this service

Boards and units from our PCB repair records

Eight units from our repair records ride an indexing conveyor. Under the gantry, the failed part is marked and replaced, then the unit is checked the way the record says it was; the plate names the unit and the repair.

Engineering process

Our workflow for this service

Start an inquiry
  1. STEP 01

    Understand

    You provide the board model, part number, fault symptoms and photographs.

  2. STEP 02

    Diagnose

    The board is inspected and the fault assessed at component level.

  3. STEP 03

    Agree

    Repair scope and quotation are confirmed with you before work starts.

  4. STEP 04

    Repair

    Approved component replacement and board restoration are carried out.

  5. STEP 05

    Verify

    Applicable checks are recorded and the board is handed over.

Verification depends on the equipment and available test conditions. Workshop checks are distinguished from testing that requires your machine, program or production setup.
