All too often PCB assemblies are damaged or degraded or the test process is disrupted due to a malfunctioning test fixture. Misplaced pushdown rods or PCBA supports, wrong probe height or force, an insufficient pressing force due to vacuum leakages or mechanic defects can damage the PCB assembly or generate pseudo failures that disrupt and disqualify the testing process. This problem may occur on all types of vacuum, pneumatic and manual fixtures. A thorough test on any fixture is and absolutely necessary step in any fixture development.
Our Fixture Testing Process is divided into several areas, each of them focusing on a different aspect of quality or functionality:
Visual Check: In this area, we look for failures or missing assembly concerning the overall fixture look and feel as well as the required labeling, identification, and safety features. During this test, we check for scratching or damaged surfaces, unfinished assemblies, proper customer labeling and component identification, correct safety indications and spare parts.
