In the manufacturing process of electronic products, testing is a very important link. The test pins are an indispensable tool in the testing process, they can help testers to detect the connectivity and electrical performance of the circuit board. Among the test pins, the most common ones are PCB test pins, ICT test pins and FCT test pins. This article will introduce the differences between these three test pins.

PCB test pin

A PCB test pin is a type of test pin used to test the connectivity of a circuit board. (custom pcb pin socket supplier china) It is often used for testing on the production line to detect whether the electrical connections on the circuit board are correct. PCB test pins usually consist of a pin seat, a spring, a needle and a conductive material. Their main function is to contact the test points on the circuit board during the test to detect the connectivity of the circuit board.

ICT test needle

The ICT test pin is a test pin used to test the electrical performance of the circuit board. (ICT testing probes price in china) It is often used for testing on the production line to check whether the electrical performance on the circuit board meets the specification requirements. ICT test needles usually consist of a needle base, spring, needle and conductive material. Their main function is to contact the test points on the circuit board during the test, so as to detect the electrical performance of the circuit board.

FCT test needle

The FCT test pin is a test pin used to test finished electronic products. It is commonly used to test whether the function and performance of finished electronic products meet the specification requirements. (ICT/FCT Standard Probe in usa) FCT test needles usually consist of a needle seat, spring, needle and conductive material. Their main function is to contact the test points of the finished electronic products during the testing process, so as to detect the function and performance of the finished electronic products.

the difference

The main difference between PCB test needles, ICT test needles and FCT test needles is their test objects and test content. PCB test pins are mainly used to test the connectivity of circuit boards, ICT test pins are mainly used to test the electrical performance of circuit boards, and FCT test pins are mainly used to test the function and performance of finished electronic products. Also, they are tested differently and in different test environments. PCB test pins and ICT test pins are usually used for testing on the production line, while FCT test pins are usually used for finished product testing.

Test pins are very important tools in the manufacturing process of electronic products. PCB test needles, ICT test needles and FCT test needles are three common test needles, and their main difference lies in the test object and test content. When selecting test needles, we need to select the appropriate test needles according to the test requirements, and use and maintain them correctly according to the characteristics and usage methods of the test needles.
