Ict In Circuit Test

Keysight in circuit test ict solutions uphold the innovative spirit of bringing you technology for tomorrow s board test challenges.

Ict in circuit test.

Disadvantages of ict testing. According to the intended area of use the environment is replicated and the electrical. Driver sensors are the active circuits that are used for making the measurements. The fabrication of the printed circuit board assembly pcba the placement of components on the board and the integrity of the parts themselves require testing to ensure the resulting end product meets quality standards.

In circuit test ict systems more than 30 years of leadership. What is in circuit testing ict. It is one of the market leaders for in circuit testing. A high quality standard for critical applications can only be achieved through a sophisticated testing strategy.

In circuit test ict 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. Using a bed of nails in circuit test equipment it is possible gain access to the circuit nodes on a board and measure the performance of the components regardless of the other components connected to them. Your electronics contract manufacturer often can t take an existing design and retrofit it for the test. With in circuit testing your board has to be designed to fit with the in circuit test fixture.

In circuit testing provides electronic manufacturers a reliable high fault coverage verification method for the assembly process. So if you want to in circuit test an existing pcb design you may have to alter said design. Keysight is a us based listed company with a broad range of products and services for measurement and test. It may be performed with a bed of nails type test fixture and specialist test equipment or with a fixtureless in circuit.

Normally drivers and sensors are always present in pairs in an in circuit test system. In circuit and function test ict fct during in circuit tests ict all components on the pcb are measured. Besides the obligatory optical inspection aoi the in circuit test ict plays a critical part as it is the only test that can verify the correct electrical values of each component tested. In circuit test ict is a powerful tool for printed circuit board test.

As the name suggests the drivers supply a voltage or current to enable a node in the circuit to be driven to a particular state. The keysight ict solutions originate from hewlett packard agilent. In doing so defective components are detected and can be replaced accordingly. Circuit check ict fixtures are robust reliable and designed for easy customization to cover a large range of pcb sizes without impacting turnaround time.
