Product Description
A PCB testing jig (or test fixture) is a specialized tool used to ensure Printed Circuit Board Assemblies (PCBAs) meet specifications before final assembly. By identifying defects like shorts, open circuits, or bad solder joints early, these jigs prevent costly manufacturing.
Key Types of Testing Jigs
- Manual Universal Frames: Standardized mechanical frames with adjustable plates, often made of bakelite and acrylic, used for various board sizes.
- Bed of Nails: Uses a series of spring-loaded "pogo pins" to make contact with specific test pads on the PCB simultaneously.
- Functional Test Jigs (FCT): Simulates the board's final operating environment to test digital I/O, voltage, and frequency.
- Automated Jigs: High-end solutions that test functionality and integrity without manual intervention, often integrated with a PC for data logging.
