In-circuit test (ICT) 

In-circuit test (ICT) system is an example of white box testing where an electrical probe tests a populated printed circuit board (PCB), checking for shorts, opens, resistance, capacitance, and other basic quantities which will show whether the assembly was correctly fabricated. It may be performed with a bed of nails type test fixture and specialist test equipment, or with a fixtureless in-circuit test setup.

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.

Why Testing Cable Harness is important?

A cable harness can also be known as a cable assembly, wire harness, wiring loom or a wiring assembly, and is best described as a string of wires or cables that are capable of transmitting informational signals or operating currents. These wires in the cable harness are then bound together with electrical tape, cable ties, conduit or clamps. Testing cable harnesses are very commonly used in construction machinery. This provides many advantages compared to loose cables or wires. Aircraft, for example, can contain many kilometers of wires/cables when extended, and by binding them together into a cable harness, they can improve safety and be made more secure. As the wires in cable harness are likely short so the installation process is made easier.

A cable assembly is a group of wires and connectors bound together with a sleeve or tape. The grouping of the wires helps save space and protects them from damage, and the assembly can be made any length, with any combination of plugs and sockets. A bespoke cable can be used for virtually any application imaginable. Cable harnesses are generally made and designed for electrical purposes, and a diagram is used for the assembly and preparation. Using a special machine, the wires are first cut to length. All high-grade automotive cable harness varieties, find application for multiple purposes. Cable assemblies are commonly used in vehicles and computers, and are also known as wiring looms and cable harnesses. With complex designs, cable harness may be needed behind the plate, although standard cables can often be used. Wall plates have significant advantages, not only in creating a cleaner look but in protecting long cables, removing trip hazards and stopping the cables collecting dust.
