PCB & Inverter Repairs
Component-level troubleshooting and repair for industrial electronics
When critical control boards or inverter drives fail, replacement costs can run into thousands of pounds - if parts are even available. Industrial Control Services provides component-level repair services for industrial control boards, inverter drives, and legacy equipment. With PCB-level troubleshooting skills and access to component suppliers, we offer cost-effective alternatives to expensive replacements, often at a fraction of the cost with fast turnaround times.
Equipment We Repair
Inverter Drives
- AC inverters (all major brands)
- DC drives and controllers
- Servo amplifiers
- Soft starters
- Power supply modules
Control Boards
- PLC I/O cards and processors
- Machine control boards
- Temperature controller boards
- HMI/operator interface panels
- Custom control circuits
Power Electronics
- IGBT modules and drivers
- Thyristor/SCR control boards
- Rectifier assemblies
- DC bus capacitor banks
- Gate driver circuits
Common Repair Scenarios
Inverter drive failures - Overcurrent trips, gate driver faults, DC bus overvoltage, IGBT failures requiring expensive replacement drives
Obsolete boards - Control boards for legacy equipment where manufacturer no longer supports the product or parts unavailable
I/O card failures - PLC input or output cards with failed channels, manufacturer wants to sell complete new card at high cost
Power supply issues - DC power supplies failing, causing intermittent control problems or complete shutdowns
Environmental damage - Boards contaminated with oil, coolant, or corrosion from harsh industrial environments
Lightning or surge damage - Power transients damaging multiple boards, need economic repair rather than replacing everything
Our Repair Services
Component-Level Diagnosis
We use oscilloscopes, logic analyzers, and in-circuit testers to identify failed components. Proper diagnosis prevents replacing boards unnecessarily and enables targeted repairs.
Inverter Drive Repair
IGBT module replacement, gate driver repairs, DC bus capacitor replacement, and power supply rebuilds. We test drives under load before returning them to service.
Control Board Repair
Replace failed ICs, relays, connectors, and passive components. We can reverse-engineer schematics for undocumented boards when necessary.
Legacy Equipment Support
When manufacturers no longer support equipment, we can often repair original boards or design replacement circuits using modern components.
Preventive Refurbishment
Replace aging electrolytic capacitors, clean contamination, and refresh solder joints before boards fail completely, extending equipment life.
Fast Turnaround Service
For critical boards, we offer priority service with typical turnaround of 2-5 working days, sometimes same-day for emergency situations.
Typical Repair Projects
- AC inverter IGBT module and gate driver replacement
- PLC I/O card component-level repair
- Machine control board reverse-engineering and repair
- Servo amplifier power supply rebuild
- Temperature controller board component replacement
- DC drive thyristor module replacement
- Contaminated board cleaning and restoration
- Legacy equipment board cloning for spares
Why Manufacturers Choose Our Repair Service
- Cost-effective - Repairs typically 30-50% of replacement cost, sometimes much less
- Fast turnaround - Usually 2-5 days, emergency same-day service available
- Legacy equipment specialists - We repair boards others won't touch
- Proper diagnosis - We find the actual fault, not just replace boards randomly
- Quality components - We use genuine or equivalent quality replacement parts
- Testing included - Boards are tested before return, with warranty on repairs
Real-World Example
A Staffordshire engineering company had a critical CNC machine controlled by a 20-year-old Siemens drive system. The main control board failed, causing complete machine shutdown. Siemens quoted £3,800 for a replacement board with 6-week delivery, and suggested upgrading the entire drive system for £15,000+ as parts were becoming scarce. We collected the failed board, diagnosed failed electrolytic capacitors and two logic ICs on the processor section. After component replacement, cleaning, and testing, the board was returned in 3 days for a total cost of £420. The machine has now run reliably for another 2 years, and we created a spare board for them by refurbishing another failed unit they had in their stores.
