The adhesive strength retained by this product after environmental testing is still good. The hardened material of this resin has good resistance to both gaseous and liquid moisture. This product complies with 2002/95EC RoHS regulations.

Due to the recent rapid development of semiconductor processing and design technology, the operating frequency and integration of semiconductor wafers have increased dramatically. The Pad shape of a device generally used in the non-memory field has an irregular 2D arrangement. One of the probe shapes that can respond to this element is the vertical probe card The cobra needle is the core component used in the vertical probe card and uses a high-density vertical insertion method. Material: P7, BC Specifications are customized according to customer needs Customized production can be made according to customer drawings and samples Stable quality and fast delivery Country of origin: South Korea, the United States

Tungsten is the most common material of cemented carbide. Compared with other metals, it has stronger hardness, ductility, and is easy to process. Among all pure metals, tungsten has the highest melting point. Compared with carbon, tungsten can maintain a solid state at a higher temperature, and tungsten has the lowest thermal expansion coefficient, with low thermal expansion coefficient, high melting point, and high tensile strength. strength. Usually tungsten is also widely used, the most common being used as a durable metal in the construction industry such as metal processing and mining. Tungsten is a metal material with high temperature resistance. Since tungsten can be drawn into a wire-like shape, tungsten is also widely used and often used as electrodes, such as filaments, electrodes, thermocouples or probe needles, etc., but tungsten itself exists The problem of brittleness and low plasticity greatly reduces its life span during use.
