PEEK IC Test Substrate

PEEK test socket

IC test sockets (test sockets, test sockets) are important fixtures in semiconductor testing. They provide a reliable, mechanically stable connection point, allowing testers to test chips and check for manufacturing defects and component failures without the need for permanent soldering or mounting on circuit boards.

When IC chips are tested in single chip, a test socket with stable dimensions at high temperature and capable of withstanding thousands of contact frictions is required. IC test sockets made of PEEK have the following advantages:

1. PEEK can withstand high static loads at high temperatures and has stable high bandwidth, low resistance and low inductance.

2. PEEK can maintain good dimensional stability in a wide temperature range, can work at a high temperature of 260°C for a long time, adapt to the working environment of -40°C to 125°C, meet the testing requirements under various extreme conditions, and ensure the high-precision dimensional stability of the IC test socket when working.

3. PEEK has high strength and ultra-high wear resistance. It can withstand tens of thousands of contact frictions of IC chips, ensuring the reliability of IC test sockets.

With the development of technology, the transistor density of semiconductor chips is getting higher and higher, and the complexity and integration of related products are growing exponentially, which is an unprecedented challenge for chip design and development.

At the same time, as the chip development cycle shortens, the success rate of tape-out is increasingly required, and any failure is a huge loss for the company. In addition, the semiconductor process technology is constantly improving, and there are many technical challenges to face. Semiconductor testing runs through the entire IC industry chain.

Choosing the right test socket material is critical because it directly affects the accuracy and reliability of the test.

Material characteristics of different IC test sockets:

1. PEEK has good comprehensiveness and is the most commonly used material, suitable for high and low temperature environments;

2. TORLON has good wear resistance, but is not suitable for high and low temperatures, and is prone to water absorption and deformation;

3. PEEK5600 is used under ESD anti-static requirements;

4. PI has good toughness, strong resistance to voltage changes, resistance to water absorption, and high melting point, but it is expensive.

What is PEEK？

PEEK and its modified composite materials show excellent performance under high temperature and high humidity conditions. PEEK have excellent chemical corrosion resistance, self-lubricating, and wear-resistant properties, so it has become the most ideal material to replace copper alloys and ordinary rubber. Compared with them, PEEK has longer service life which can reduce equipment operating costs, improve equipment operating reliability.

High Temperature Performance

PEEK’s performance can remain stable in the temperature range from -196°C to 260°C. Under extreme working conditions, it can withstand 300″C for a short time. The performance of PEEK is still reliable even in high temperatures of several kilometers underground work environment.

High Strength and Wear Resistance

Compared with other plastics, PEEK is resistant to compression, impact and also have good fatigue resistance. PEEK is durable in mechanical equipment and wear-resistant environments.

Double the Service Life

PEEK sealing solutions can improve the part service life. Some domestic chemical companies use the PEEK5600FE20 polytetrafluoroethylene modified material designed by JUNHUA PEEK to replace the original material, the service life of the wear parts can even be extended by 1.3-3 times.

Corrosion Resistance

PEEK is chemically inert, and has no reaction to most acids, oils, greases and all other organic and inorganic solvents or enzymes, and can still maintain good strength and dimensional stability.

Self-lubricating

PEEK has low friction coefficient, low running resistance, can be used without oil in some working conditions. The equipment is cleaner, thus improving process reliability, improving energy efficiency and saving costs.

More dom in Design

Injection molds can be used for rapid injection molding of large quantities of complex special-shaped parts, and the cost is low compared to machining.
