The products are mainly used in the testing of various electronic and peripheral products such as: semiconductor components, CPU chips, PCB circuit boards, LCD screens, Camera cameras, IOT, Internet of Things cars, and other peripheral electronic products.

Composition of ICT probes



The commonly used ICT test probe is composed of three components: needle, outer tube and spring. Since the ICT probe pays great attention to its properties such as conductivity, durability and hardness in the application, the electroplating is very important in the manufacturing process. very important part. These parts must be specially plated before assembly, so that a probe with electrical parameters that meet the standards can be assembled.

The gold plating of the probe is also very particular. The entire part of the needle tube needs to be gold-plated, including the inner and outer walls. The inner and outer walls are all gold-plated, and the gold-plating of the needle tube is completed. Due to cost reasons, many manufacturers do not electroplate the spring, but if there is a high demand, the spring also needs to be electroplated.

On the other hand, ICT probes also need to be able to meet the characteristics of wear resistance and low impedance, so when choosing basic materials, the needles are often beryllium copper or SK-4, the needles are phosphor bronze, and the springs are piano steel wires. , all materials are gold-plated.
