PCBA Testing & Quality Control

At ERC TECH, we ensure every PCBA meets the highest standards through comprehensive testing and quality control. PCBA testing evaluates boards with installed components to verify electrical conductivity, input/output performance, and compliance with design specifications.

For large-scale production, we provide specialized fixtures to streamline testing. These fixtures connect PCB test points and measure critical data such as voltage and current, enabling fast and accurate verification. Our engineers work closely with customers during PCB design to reserve test points and provide detailed testing documentation.

Why PCBA Testing Matters

PCBA testing is a vital step in ensuring product reliability. The manufacturing process involves PCB production, component sourcing, SMT placement, DIP assembly, and more, where errors can occur due to equipment or handling. Our experienced R&D and testing team customize solutions to deliver high-quality, reliable PCBAs that meet customer requirements.

Visual Inspection: Manual checking of solder joints and components to detect defects.
In-Circuit Testing (ICT): Probes test the assembled PCB for shorts, open circuits, resistance, capacitance, and correct component placement.
Automated Optical Inspection (AOI): Cameras scan for missing parts, misalignments, or defects in soldering and components.
Functional Circuit Test (FCT): Tests powered PCBAs for voltage, current, power, frequency, brightness, sound, motion, FLASH, EEPROM, and other functional parameters.
Sample Inspection: First article checks before batch production ensure SMT and assembly processes are correct.
X-Ray Inspection: Non-destructive testing of hidden PAD components like BGA and QFN, detecting internal defects or foreign material.

Our PCBA Testing Process

Most ERC TECH PCBA orders undergo customer-specified testing before shipping. Test procedures are recorded, documented, and shared with customers, ensuring transparency and reliability. Any issues discovered during testing are addressed immediately in consultation with our clients.

With ERC TECH, PCBA testing is not just a process—it’s an essential step in delivering safe, high-performance, and durable electronics.
