PCB board testing is an important part of the electronic manufacturing process, which can help manufacturers detect and verify the performance and reliability of circuit boards. Test probe is a tool for PCB board testing, it can help testers quickly locate circuit board faults, and improve testing efficiency and accuracy. ( low price Coaxial Probe For Car Supply china)This article will introduce the types and characteristics of test probes used for PCB board testing.

needle test probe

Needle test probe is a common PCB board testing tool, which usually consists of a set of needles and a fixed base. （test probes manufacturer china）The tester can insert the needle into the test point on the PCB board, and the test result is transmitted to the test instrument through the cable on the base. The needle-type test probe has the advantages of simple structure, convenient use, and high test accuracy, but requires manual operation, and the test efficiency is low.

spring loaded test probe

A spring-loaded test probe is an automated PCB board testing tool that usually consists of a set of springs and a fixed base. (brass charging pogo pin supplier china)  The tester can place the PCB board on the base, and connect the test point with the test instrument through the spring. The spring-type test probe has the advantages of high degree of automation, high test efficiency, and high test accuracy, but the price is relatively high.

Magnetic Test Probe

A magnetic test probe is a special PCB board testing tool, which usually consists of a set of magnetic needles and a magnetic base. The tester can place the PCB board on the magnetic base, and connect the test point with the test instrument through the magnetic pin. The magnetic test probe has the advantages of simple structure, convenient use, and high test efficiency, but requires a special magnetic base and magnetic needle, and the price is relatively high.

Vacuum Test Probe

The vacuum test probe is a high-precision PCB board testing tool, which usually consists of a set of vacuum suction cups and a fixed base. The tester can place the PCB board on the base, and connect the test point with the test instrument through the vacuum suction cup. The vacuum test probe has the advantages of high test accuracy and high test efficiency, but requires a special vacuum suction cup and base, and the price is relatively high.

In short, there are many types of test probes used for PCB board testing, and each test probe has its own characteristics and scope of application. Testers need to select appropriate test probes according to actual needs and budget to improve test efficiency and accuracy.
