Got PCBs from previous suppliers that need fixing? Field returns piling up? Prototype boards requiring modifications? Before investing in complete remanufacturing, HILPCB can repair your existing boards—saving time and costs.
As a PCB manufacturing and assembly factory, we leverage our production equipment and IPC-certified technicians to repair boards from any source. The same expertise we use to manufacture high-quality PCBs helps salvage your valuable assemblies.
Who Needs PCB Repair Services?
Your Existing Inventory Issues
Field returns from customers: Component failures, environmental damage, or handling issues create warranty returns. Instead of scrapping entire assemblies, replace failed components and return boards to service.
Boards from previous suppliers: Inherited PCBs with quality issues from other manufacturers? We fix lifted pads, broken traces, and solder defects—giving these boards a second life.
Old stock requiring updates: Design changes or component obsolescence means existing inventory needs modifications. We implement ECO changes faster than remanufacturing new batches.
Development prototypes: Engineering changes during R&D require board modifications. We modify traces, swap components, and adjust circuits—accelerating your development cycle without waiting for new fabrication.
Common Repairable Defects
Lifted or damaged pads: Reconstruct pads using thermally-bonded copper foil, restore electrical connections with jumper wires. IPC-7721 compliant procedures ensure reliability.
Broken traces: Surface traces repaired with jumper wires; internal layer damage accessed through precision via drilling.
Failed components: Remove and replace ICs, BGAs, capacitors, resistors using hot air rework stations—from 0402 passives to complex packages.
Damaged plated through-holes: Eyelet insertion restores electrical continuity and mechanical strength.
Solder defects: Bridges, cold joints, and insufficient solder corrected using proper reflow techniques.
Solder mask damage: UV-curable LPSM protects exposed copper, preventing oxidation and shorts.
Why Manufacturers Make Better Repair Partners
Unlike dedicated repair shops, we're a full-scale PCB manufacturing facility offering repair as a value-added service:
Production-grade equipment: Your boards get repaired using the same hot air stations, reflow ovens, and X-ray inspection systems we use for manufacturing—not basic repair tools.
IPC-certified assembly technicians: Our team handles BGA rework, micro-component placement, and complex assemblies daily in production. Repair work leverages this expertise.
Process understanding: We know why defects occur and how to prevent them. When repairing your boards, we identify root causes and recommend improvements for future production.
Quality documentation: Full traceability with repair records, photos, and test results—meeting your audit requirements.
Faster turnaround: Existing production infrastructure means no waiting for specialized repair equipment. Most repairs completed in 3-5 business days.
BGA Rework & Complex Package Repair
Advanced packages require precision equipment we use routinely:
- Temperature-controlled removal with thermocouple monitoring
- Professional reballing with matched stencils
- X-ray inspection verifying void-free joints
- Precision placement (±0.05mm alignment tolerance)
- Validated reflow profiles for each package type
Our PCB rework capabilities handle micro-BGAs, flip chips, QFNs, and other advanced packages commonly used in modern designs.
Prototype Modifications & ECO Implementation
Engineering changes during development:
- Component value changes
- IC upgrades or swaps
- Trace cuts and jumper wire routing
- Additional component installation
- Circuit redesigns for validation testing
Time savings: Modifications completed in 2-3 days versus 2+ weeks for new board fabrication and assembly.
Repair Feasibility Assessment
We recommend repair when:
- Board value exceeds repair cost ($200+ assemblies)
- Defects are localized and repairable
- Lead time for new manufacturing is unacceptable
- Small quantities don't justify new production setup
New manufacturing recommended when:
- Extensive damage across multiple areas
- High-volume needs (repair doesn't scale)
- Board design issues requiring layout changes
- Component obsolescence affecting multiple parts
Transparent pricing:
- Component replacement: $25-$50
- Pad reconstruction: $50-$100 per pad
- Trace repair: $40-$80 per trace
- BGA removal/replacement: $150-$300
- Minimum service: $200-$300
Volume discounts available. We'll assess your boards and recommend repair versus remanufacturing honestly.
Quality Standards & Testing
Every repair includes:
✓ IPC-A-610 Class 2/3 visual inspection under magnification ✓ Continuity and isolation testing ✓ Functional testing when specifications provided ✓ X-ray inspection for BGA and hidden joints ✓ Complete documentation with photos and test results
From Repair to Full Manufacturing Partnership
Many customers start by working with us on PCB design iterations, later expanding to complete manufacturing and testing solutions as their production needs grow.
Test us first: Repair services showcase our technical capabilities and quality standards before you commit to larger production orders.
Smooth transition: Once you see our workmanship on repairs, you'll understand what to expect from our PCB assembly and manufacturing services.
Design feedback: While repairing your boards, we often identify design improvements that reduce future defects—valuable insights we incorporate when you move production to us.
Relationship building: Repair projects create working relationships with our engineers and quality team before larger commitments.
Need to salvage existing PCBs or explore manufacturing options? We handle both. Repair services demonstrate our technical depth, while our manufacturing capabilities deliver quality production runs.

Common Questions
When does PCB repair make more sense than rebuilding or remanufacturing?
Repair is usually worth evaluating when the board itself is valuable, the fault area is limited, and a fresh build would take too long. If the damage is widespread or the root cause comes from the design itself, remanufacturing is often the more controllable path.
Can complex packages such as BGA and QFN really be repaired reliably?
Yes, but only when the shop has proper rework equipment, thermal profiling, and inspection capability. Hidden-joint packages usually require more than technician judgment alone, often including reballing, X-ray confirmation, and functional retest.
How long does a typical PCB repair project take?
Many standard repairs can be turned in three to five working days, but the real timeline depends on the failure mode, component availability, and whether additional testing is needed. Complex package rework or trace reconstruction usually extends the schedule.
What information should be prepared before sending a board for repair?
At minimum, provide the failure symptoms, board revision, schematic or reference designator context, and the standard for retest acceptance. Photos of the suspect area, prior rework history, and end-use information help the engineering team decide much faster whether repair is the right path.
