What is the test in the circuit?

The test in the circuit is a test that ensures that there are no shorts, resistors or other problems with flat circuits (PCB) boards. The purpose is to ensure proper production and quality in PCB. The most common method of testing in the circuit is the testing nail test, in which the PCB is pushed against the connecting pins panel so that the pins can check any electrical problems. There are nail nail testers that are deployed and vacuum tightening, with a vacuum generally considered better but also much more expensive. Although this test can help manufacturers test PCB problems, there are restrictions such as defective main proposals; Contacts also cannot be tested. There may be several problems during the production process to prevent PCB. PCB machines can be broken, or some of the smaller components may be defective. If you want to check the circuit function, a circuit test is performed.

The most common way of performing the test in the circuit is the location of the PCB per afterControl called nail bed, so -called because it uses many electrical contact pins that look together like a nail bed. PCB is located on the device to start the test. The contacts then push PCB power to check problems such as shorts, resistors or breaks in the circuit.

Facilities

Bed-of-ails are categorized depending on how PCB ensures contacts. In the push-down method, the PCB is only pushed against the nails to contact. The vacuum version uses vacuum seals to suck PCB into contacts. These two are adept when performing the test in the circuit, but the vacuum version is more efficient and the push-down method is cheaper. Both versions tend to leave small marks in the tested PCB, but this does not affect functionality.

Performing the test in the circuit will help manufacturers to find defects with PCB, but the process is not infallible. While testing in the circuit can test the circuit to ensure correct PPCB power rotation and that all parts of the circuit work cannot test PCB contacts that can prevent PCB from working on your computer. If the design of the PCB is defective or susceptible to easy breaking, it can also cause problems, as the test can ensure that the design of the circuit works, not how durable it will be.
