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.

| ICT Test Fixtures |
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. Please visit site
