Screening

This is a test conducted before using electrical and electronic equipment in factory inspections to check for potential defects that could cause malfunctions. By removing products with identified defects before shipment, the failure rate is reduced, improving product reliability. The test is conducted using X-rays, ultrasound, infrared rays, etc. Compared to impulse tests, impact tests, and vibration tests, methods that do not place significant stress on the equipment are often used.
