In the production of PCB test fixtures, the following materials are commonly used:

Aluminum alloy: Aluminum alloy is a common material with good thermal conductivity and mechanical properties. It can effectively dissipate heat, prevent overheating during testing, and has high strength and durability, allowing it to be used for a long time without deformation or damage.

Stainless Steel: Stainless steel is a corrosion-resistant material with good mechanical properties and durability. It can resist the erosion of chemical substances and maintain the stability and accuracy of the test fixture. Stainless steel also has high hardness, which effectively prevents scratches and wear.

Polymer Materials: Polymer materials are lightweight and easy-to-process materials that are often used to make the housings and support structures of test fixtures.(What are the four types of test probes?) Polymer materials have good insulating properties and can prevent current leakage and short circuits. In addition, polymer materials also have high wear resistance and corrosion resistance, which can protect the test fixture from the external environment.

Silicone: Silicone is a soft and elastic material often used to make gaskets and seals for test fixtures. Silicone has high temperature resistance and chemical resistance, and can remain stable in high temperatures and corrosive environments. In addition, silicone also has good insulation and waterproof properties, which can prevent current leakage and moisture intrusion.

To sum up, the material selection of PCB test fixture is very important. Aluminum alloy, stainless steel, polymer materials and silicone are commonly used materials. They have the characteristics of thermal conductivity, corrosion resistance, insulation and softness respectively, and can meet various requirements of test fixtures. During the production process, it is necessary to select appropriate materials according to specific testing requirements and environmental conditions, and carry out reasonable design and processing to ensure the stability, accuracy and durability of the test fixture.
