The pogo pin consists of three parts.Connector company

　　The needle Plunger brass is gold-plated, the needle tube is brass gold-plated, and the spring spring stainless steel test needle is a probe used to test PCBA. The surface is gold-plated, and there is a high-performance spring with an average life span of 30,000 to 100,000 times inside. The more famous foreign manufacturers include: QA, IDI, UC, Semiprobe, ECT, INGUN,

　　Material of pogo pin manufacturer probe: W, ReW, CU, A+

　　1. The main materials used are W, ReW, general elasticity, easy to shift, sticking to gold chips, need multiple cleaning, long wear and tear, and average life.

　　2. The need for cleaning needles made of A+ material has good elasticity, is not easy to shift during the test, does not stick to gold chips, and does not need to be cleaned, so it has a long life.

　　Electrical properties: The main electrical properties of the connector include contact resistance, insulation resistance and dielectric strength.

　　1. Contact resistance High-quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector ranges from a few milliohms to tens of milliohms.

　　2. Insulation resistance is a measure of the insulation performance between the contacts of electrical connectors and between the contacts and the shell. Its magnitude ranges from hundreds of megohms to thousands of megohms.

　　3. Dielectric strength, or withstand voltage, dielectric withstand voltage, is the ability to withstand the rated test voltage between the connector contacts or between the contacts and the shell.
