This enhances electrical performance, longevity, and reliability, meeting industry standards and reinforcing our commitment to delivering high-quality, impurity-free electronic assemblies every time.

BGA Rework

Green Circuits provides precise BGA rework, using advanced techniques to troubleshoot and repair complex PCBs. Our skilled technicians handle component salvage, circuit modifications, pad/trace repair, solder mask restoration, and X-ray inspection, ensuring high-quality, reliable rework solutions for a wide range of PCB issues.

System/Box Build

Green Circuits offers turnkey system/box build services, integrating PCB assemblies, wiring, enclosures, software, and testing into ready-to-use products. Our custom-built stations ensure efficient assembly, packaging, and fulfillment, providing high-quality solutions for complex electronic systems.

Quality Control and Testing

Automated Optical Inspection (AOI)

Green Circuits’ AOI process ensures precision and quality in PCB assembly by using high-resolution cameras to detect soldering errors, missing components, and misalignments. This critical step verifies component placement, reducing defects and ensuring high-reliability PCB production.

XRay Inspection Machine

Green Circuits uses Nordson DAGE XD7600NT Ruby X-Ray Inspection to detect hidden soldering defects and misalignments with unmatched precision. This ensures flawless PCB quality, exceeding reliability standards for complex electronics, making our boards ready for high-performance, mission-critical applications.

Flying Probe Electrical Testing

Green Circuits uses three flying probe testers for precise, fixture-free electrical testing of PCBs. These machines detect defects, verify connectivity, and assess component values, making them ideal for prototypes and low-volume production, ensuring high reliability and quality in complex PCB designs.

Final Quality Control Inspection

Every PCB undergoes rigorous hand inspection and testing before shipment. Our IPC-certified inspectors verify solder quality, accuracy, and compliance using customer drawings and specifications, ensuring flawless performance and meeting strict quality standards in every final stage of production.
