Model - Rhenium tungsten Probe Needles
Rhenium-tungsten probes are mainly used in semiconductor, LED, LCD and other industries, and are used in probe cards, probe stations, chip testing, wafer testing and LED chip testing.
Rhenium-tungsten needles have good hardness and fatigue resistance, and good stability. Probe cards made of rhenium-tungsten needles are suitable for long-term testing, but the cost of rhenium-tungsten needles is lower than that of tungsten needles. The cost of rhenium-tungsten needles is relatively higher than that of tungsten needles. .
The material-related properties of rhenium-tungsten needles are similar to those of tungsten probes. Its elasticity and conductivity are the same as those of tungsten probes, and its contact resistance and service life are better than those of tungsten probes.

Palladium alloy probes are high-quality alloys used for demanding low-energy electrical contacts. Paliney 7 is a palladium-silver age-hardenable alloy. The alloy has a reliable service life of more than 50 years and is very suitable for demanding applications that require extremely long life, stable contact resistance and low electrical noise. The features of Paliney 7 include high corrosion resistance and rust resistance, while providing the mechanical properties of beryllium copper. Applications include guidance systems for military hardware, satellite communications, high-speed slip rings, and drug delivery systems. Paliney 7 meets the standards for electrical contact alloys.
The probes commonly used in the industry are four kinds of materials: tungsten, rhenium tungsten, beryllium copper, and Palinery-7TM. Rhenium tungsten is usually selected. Among them, rhenium tungsten has similar properties to tungsten and has a better life and contact resistance than tungsten.

The tungsten needle is an ultra-sharp electrode made of refractory alloy for scientific instruments. The electrode has a blunt tip and a pointed bottom. It is composed of a refractory alloy with an ultra-large electrode method with a vertical axis of rotation. The molten oxidant can be removed and replaced cyclically. Pool pole.
Tungsten has the highest melting point among metals. It can be used as a filament. It can be made into high-speed steel, drill steel, etc. when added to iron. It is resistant to wear and corrosion, and is not afraid of deterioration or deformation due to high heat caused by friction.
In the use and research of tungsten, the most famous one is that Edison used tungsten filaments to make light bulbs, which ushered in a bright era for mankind.
Tungsten needles are the most commonly used probe material when testing test pads, and tungsten needles have high hardness and a long service life, and the relative test scratches will be relatively large. In addition, tungsten needles have certain The elasticity is relatively stable during the needle test.
