Pure tungsten probe is made using high-quality pure tungsten (99.95-99.98%) as a raw material through a deep process, and has characteristics of high precision, high strength, good wear resistance, good corrosion resistance, relatively good elastic modulus, high finish (below Ra0.25), and long service life. More details, please visit: http://tungsten.com.cn/tungsten-needles.html The needle tip of high precision pure tungsten probe is controlled to a minimum of 0.08 microns (80 nanometers), which is mainly used in the semiconductor industry. In other words, such…

Rhenium tungsten probe is a needle made of rhenium tungsten alloy wire containing 3% rhenium. The needle tip of such a probe is processed by a special process with the advantages of high precision, high strength and elastic modulus. So, the probe is more wear-resistant and corrosion-resistant. The surface of the probe is smooth, and the finish can reach Ra0.25 or less. More details, please visit: http://tungsten.com.cn/tungsten-needles.html Rhenium tungsten probes have different tip types, i.e., different tip shapes, such as,…

Tungsten needle is often used as an ablation electrode, which is mainly made of 99.99% high purity tungsten, having the characteristics of high melting point and high temperature stability. More details, please visit: http://tungsten.com.cn/tungsten-needles.html What is an ablation electrode? The ablation electrode is an accessory of high-frequency surgical equipment. It ablates, stanches, electrocuts, electrocoagulates, attracts, and peels off related tissues during surgery. It has been used to replace traditional scalpel and is widely used in surgery. Why choose tungsten needles…

Ion fan is a kind of static electricity eliminator, which is mainly composed of high-voltage power generator and discharge needle – tungsten needle. Generally, a high voltage above 4 kV is applied to the discharge needle, therefore, the tip of the discharge needle is loaded with a very large energy load. And it is the main reason for the wear of tungsten needles. In addition, pollution will increase the corrosion and wear of tungsten needle electrodes. More details, please visit:…

Tungsten is a superior material for fabricating needle. And tungsten needle is the most important semiconductor test probe. Tungsten probes are mainly used in the final testing stage of processes of semiconductors. And the tungsten probe used to connect the chip to the test board is an important factor that affects contact and electrical characteristics of dies. Generally speaking, the tungsten needle as a probe is to identify good and bad dies, thereby reducing unnecessary packaging cost. More details, please…

Tungsten needle with two tips may be a sharpened pure tungsten needle, a sharpened tungsten alloy needle or a sharpened rare earth doped tungsten needle. And one of the most important applications of tungsten needle is – electrode. The pure tungsten electrode has a high melting point, strong electron emission capability, high elastic modulus, and ablation resistance, so that it can be used in tungsten arc welding, and it plays an important role in arc starting, arc stability and welding…

Polymer tungsten, also known as an ideal lead-free radiation shielding material, is a newly developed radiation shielding material to replace lead and lead alloy for fabricating medical protective products. And what the researchers have in common is a focus on polymer tungsten property with the popularization of tungsten polymer applications. So, what are the properties of polymer tungsten? More details, please visit: http://poly-tungsten.com/index.html Polymer Tungsten Properties Perfect radiation shielding performance: With higher density, it has better shielding performance than lead…

Polymer tungsten is a soft radiation shielding material made of tungsten powder and high molecular polymer (one or more of plastic, rubber or thermoplastic elastomer) through extrusion molding, injection molding or compression molding process. And polymer tungsten radiation protection material can play a good role in blocking X-rays, gamma rays and other radiation rays, so it has been used to produce protective clothing and other medical protective products. More details, please visit: http://poly-tungsten.com/index.html As a soft radiation shielding material, the…

How to recycle tungsten wafer probe? You know, in order to reduce the cost of wafer probing, recycling of tungsten probe is very important. According to the experts, during testing, the tapered tungsten needle began to wear after multiple tests, resulting in a larger diameter of needle tip. At this time, if you do not replace the probing card (one of the tools for wafer testing) containing tungsten needle, it will affect the accuracy of the test results; and if…
