Tungsten needle is a slender tungsten product made of pure tungsten or tungsten alloy. It has the advantages of high temperature resistance, high hardness and good electrical conductivity. It can be used as an electrode material for argon arc welding technology and can also be used as an instrument The probe can also be used as a dissecting needle. The double-head sharpened tungsten needle can be a pure sharpened tungsten needle, a tungsten alloy sharpened tungsten needle or a rare earth doped sharpened tungsten needle.
Our company has patented materials such as tungsten rhenium, tungsten rhenium copper, etc., using high-purity tungsten, rhenium and other raw materials, and a special production process to ensure that the tungsten rhenium alloy has high uniformity and density. The probes produced are in conductivity, The elastic modulus, durability, mechanical strength, etc. can meet the needs of customers.
The shape of the needle tip can be customized according to requirements, with sharp, platform, arc and other shapes, ranging from micrometers to nanometers, the minimum curvature radius of the needle tip can be controlled at 50 nanometers, and the finish is Ra0.25. All microscopic inspections before shipment to ensure product consistency .
Application
Mainly used in static elimination, semiconductor chip, wafer inspection and medical minimally invasive surgical electrosurgical unit.
