Workability of ICT Test Fixtures

We are living in a technological world that is getting more and more complex by the day. New and newer forms of gadgets, tools and machines are being invented by numerous inventors and technocrats. These inventions are more complex than the previous one and also such machines and devices were possible due to inclusion of PCB or printed circuit board. Now the question is how these printed boards can be tested in the case of some sort of malfunction or while making them in a production line. Today, we will be having a detailed analysis about how these PCB boards are tested.

These ICT Test Fixtures are specially used for an In-circuit test that is an example of a white box testing, where an electrical test fixture tests a populated printed circuit board. These test fixtures are used for checking for shorts, opens, resistance, and capacitance as well as to check for other basic types of electrical failures and malfunctions that will show up whether the assembly is correctly made-up or not. All such types of tests will be performed with the help of bed of nails types of test fixture as well as with the assistance of other specialist electrical equipments.

Thus, the ICT Test Fixtures are of many types. Bed of Nails tester is one of them. It is a classic electronic test fixture that has numerous pins inserted into a hole that aligned using tool pins to make contact with the test points on a printed circuit boards. These fixtures are also connected to a measuring unit by wires. Such a tester devices contain an array of small and tiny spring loaded pogo-pins. Each such pogo pin makes a contact with one node in the circuitry of the device under test. Hence by pressing this particular DUT against the bed of nails, trustworthy contact can be rapidly made with hundreds of IPTs also known as Individual Test Points within the perimeter of the DUT.
