A bed of nails checker may be a ancient electronic check fixture that has various pins inserted into holes in AN epoxy phenolic resin glass fabric laminated sheet (G-10) that square measure aligned victimisation tooling pins to form contact with test points on a computer circuit board and also are connected to a unit of measurement by wires. Named by analogy with a real-world bed of nails, these devices contain AN array of tiny, elastic device pogo pins; every pogo pin makes contact with one node within the electronic equipment of the DUT (device beneath test). By pressing the DUT down against the bed of nails, reliable contact may be quickly and at the same time created with a whole bunch or perhaps thousands of individual check points at intervals the electronic equipment of the DUT. The restriction force is also provided manually or by suggests that of a vacuum or a mechanical presser, so propulsion the DUT downward onto the nails.
Bed-of-Nails check itself because of the limitation of principle and technique, featured with severe technological challenges. however as I delineated on top of, there still has benefits different strategies don’t have. With the utilization of recent and improved technology and fixture technology, it'll even have robust vitality within the field of electrical testing.
