Inspection & Quality Testing

TH-Electronics offers advanced PCB testing methodologies, including In-Circuit Test (ICT), Flying Probe Test (FPT), and Functional Circuit Test (FCT), to verify each board’s electrical performance.

Our commitment to rigorous testing ensures electrical connections on the PCB are correctly established and there are no defects, such as shorts, opens, or incorrect component placements, ensuring our clients receive PCBs meeting their exact specifications.

Electrical testing and certification are vital for verifying the component’s functionality, ensuring the board operates correctly in its intended application, and maintaining the performance and reliability of the final product.

Our commitment to excellence is driven by our cutting-edge technology and extensive technical expertise.

PCB Testing Methods

Automated Optical Inspection (AOI)

Uses high-resolution cameras to detect surface-level defects, such as missing components, incorrect polarity, or solder bridges.

Boundary Scan

An automated method for testing interconnects on high-complexity boards where physical probe access is limited.

Burn-in Testing

Subjects the board to extreme conditions (e.g., high heat or voltage) for an extended period to identify components prone to failure.

Chemical & Physical Analysis

Testing for ionic cleanliness, flammability, and peel strength of the copper traces.

Environmental Testing

Includes thermal shock, humidity cycling, and salt fog testing to ensure durability in harsh conditions.

Flying Probe Testing

Uses moving probes to test electrical performance; highly flexible because it does not require custom fixtures, making it ideal for low-volume prototypes.

Functional Testing

Simulates the final operating environment to verify that the board performs its intended electronic functions as expected.

In-Circuit Testing (ICT)

Often called the "bed of nails," this uses fixed probes to check for shorts, opens, and component values like resistance and capacitance.
