Test socket in back-end chip testing
In the microchip manufacturing process it is important to test the chips under various conditions to ensure specific functionalities as well as durability. Different test sockets are used to test numerous microchips, as specified by integrated circuit designers. As several types of high-performance and engineering plastics are used to manufacture test sockets, the demand for plastic materials continues to grow rapidly.
The same basic properties need to be provided by all variations of test sockets. These include high dimensional stability over a wide temperature range, good machinability with minimal burr formation and good mechanical strength and stiffness. These properties are important because the test sockets have to pass various tests, and at the same time be resistant and durable during various cycling tests. Furthermore, the choice of material for IC test socket applications is based on operating temperature, electrical properties, and accordingly relative cost.
In the field of test sockets we particularly recommend:
