Bed Of Nails Electrical Tester

A bed of nails tester is a traditional electronic test fixture which has numerous pins inserted into holes in an epoxy phenolic glass cloth laminated sheet g 10 which are aligned using tooling pins to make contact with test points on a printed circuit board and are also connected to a measuring unit by wires.

Bed of nails electrical tester. Either bed of nails fixture test or flying probe test the tested items mainly cover from opens shorts capacitance to resistance in a circuit on each bare board.

We either use the bed of nails fixture method or the flying probe method to perform the testing in our circuit board manufacturing process. The holes for the pogo pin sockets had a high aspect ratio so the pogo pins aligned themselves well in the vertical. So that ideal performance and all functions of bare boards can be totally realized in your practical projects. Electrical connections were done with discrete wires point to point.

Mechanically or electrically actuated options. There are many very expensive solutions to that but you will learn here how to create your own bed of nails tester by simply using a 3d printer. The unit will also optically read leds and key segments off lcd displays. Bittele electronics performs 100 electrical testing on all bare pcbs produced at its facilities as per ipc 9252 specifications.

The resulting bed of nails board was stiff. Designed primarily for testing products in plastics. In circuit test fixture basics. In addition some reports can be summarized through testing results including cross section solderability peel strength etc.

Probes top bottom and all 4 sides. It will have a main connector that interfaces to the tester and wires that are taken from the connector to individual pins probes or nails that make contact with the required. Solenoids will press buttons and servos. The test bed looks like a bed of nails as well hence the name.

Central camming mechanism pull plates inward. These design choices for the bed of nails allowed several useful properties. The in circuit test fixture is required to interface the main tester with the particular board under test. Although the concept of the in circuit test fixture or bed of nails is broadly the same whatever manufacturer is used there are a number of variations on the basic theme.
