Advanced Processes in BGA Rework and Repair
Modern electronics demand surgical precision when addressing component-level failures. Our approach combines advanced X-ray inspection systems with refined repair methods to deliver reliable solutions for complex BGA challenges.
Precision Component Handling
Specialized thermal profiling enables safe extraction of sensitive components without damaging circuit boards. We recover reusable BGAs through controlled heating cycles that preserve electrical characteristics – critical for maintaining equipment longevity in high-value assemblies.
Defect Detection Redefined
Our 5-micron resolution X-ray systems reveal hidden flaws standard methods miss. The table below shows how our inspection compares to conventional approaches:
| Inspection Type | Defects Detected | Accuracy Rate |
|---|---|---|
| Visual | Surface defects only | 62% |
| X-Ray | Internal voids, bridging, joint integrity | 99.8% |
| Thermal | Heat distribution issues | 85% |
This level of scrutiny ensures every repair meets aerospace-grade standards. For modified designs, we rework circuit patterns at BGA sites using micro-routing tools that maintain signal integrity.
When combined with our advanced PCB solutions, these processes create a complete quality ecosystem. Missing pads get restored using IPC-certified materials, while salvaged components undergo full performance validation before reuse.
Expert BGA Soldering and Component Services
Precision soldering separates functional boards from costly failures. We combine automated systems with three decades of process expertise to address modern electronics' most demanding assembly challenges.
State-of-the-Art Reflow Soldering Techniques
Our Yamaha Pick & Place machines position components within 15-micron tolerances. Real-time thermal mapping adjusts heating zones during reflow cycles. This prevents warping in multilayer boards while achieving perfect solder joint formation.
Custom profiles adapt to unique package configurations. Lead-free formulations meet RoHS standards without compromising joint reliability. We validate every profile through 72-hour stress testing before production.
Customized Solutions for Challenging PCB Designs
High-density layouts require millimeter-level precision. Our engineers redesign solder mask openings for tight-pitch BGAs. Thermal relief patterns get optimized to manage heat dissipation in compact spaces.
Prototype batches receive the same scrutiny as full production runs. Multiple inspection checkpoints verify component alignment before permanent placement. This approach eliminates rework costs while maintaining schedule commitments.
Flexible service options scale from single-board debugging to 10,000-unit orders. Clients gain consistent quality regardless of project size – a critical advantage when updating legacy systems or launching new designs.
Our In-House Capabilities for BGA Rework and Reballing
Production demands evolve rapidly across industries. We deliver adaptable solutions matching your exact scale and technical needs. From prototype debugging to full-scale production, our processes maintain identical quality benchmarks.
Tailored Solutions Across Production Volumes
Our systems handle components as small as 3x3mm with 4 balls up to 60x60mm packages exceeding 8,000 connections. Pitch tolerances down to 0.3mm meet tight space requirements in compact designs. Multiple alloy options ensure RoHS compliance without compromising thermal performance.
Low-volume projects benefit from manual solder braid techniques allowing component-level adjustments. High-volume orders leverage automated vacuum systems removing old solder 18x faster than traditional methods. Both approaches preserve board integrity through controlled thermal management.
Quality Verification at Industrial Scale
Every reballed component undergoes three-stage validation. Laser measurement confirms ball diameter accuracy within ±5μm. Automated optical inspection checks coplanarity across all connections. X-ray analysis verifies joint integrity before final electrical testing.
This multi-layered approach catches defects standard methods miss. Aerospace clients particularly value our 100% traceability protocols. Production batches include digital records documenting alloy composition, pitch measurements, and compliance certifications.

Component reliability defines success in mission-critical electronics manufacturing. We provide precision reballing services combining advanced X-ray inspection with multi-stage quality checks. Trusted by aerospace and medical sectors, our methods meet strict industry standards while adapting to unique production needs.
Monthly processing of thousands of components demonstrates scalable expertise. From single-unit repairs to 10,000-unit batches, every project receives identical scrutiny. Our advanced BGA rework process ensures proper solder ball formation through controlled thermal profiles and post-repair validation.
Three-layer verification protocols eliminate hidden defects. Laser measurements confirm ball dimensions, while automated systems check alignment. X-ray analysis then validates joint integrity before components return to service.
Continuous improvement keeps solutions at technology’s forefront. We maintain compliance with evolving industry requirements while delivering components ready for immediate assembly. When failure isn’t an option, our processes provide the reliability global manufacturers demand.
FAQ
How do you ensure RoHS compliance during BGA reballing?
We use SAC305 or other lead-free solder alloys certified to meet RoHS standards. Our reflow profiles are calibrated to prevent oxidation while maintaining precise temperature control, ensuring compatibility with modern eco-friendly manufacturing requirements.
Can you handle ultra-fine pitch BGA components below 0.4mm?
Yes. Our semi-automated placement systems and JBC Nano soldering stations support components down to 0.3mm pitch. We combine solder paste printing with precision ball grid alignment for reliable micro-BGA rework.
What quality checks are performed after x-ray inspection?
Every reworked BGA undergoes electrical testing, thermal cycling stress tests, and visual inspection under 10X magnification. We document void percentages, ball alignment, and joint integrity using Nordson DAGE XD7600NT imaging systems.
Do you support both low-volume prototyping and high-volume production?
Absolutely. Our flexible work cells accommodate single-board repairs through to batch processing of 500+ units. Automated optical inspection (AOI) systems scale quality control for large orders without compromising turnaround times.
