Tungsten needle is an important part of a wafer probe card, so it is also known as tungsten probe in such a probe card. According to the experts, a probe card, as a main tool for wafer testing, is usually composed of a test circuit board and a conical tungsten needle bent at 95-105 degrees on the circuit board. During the test, the tip of the tungsten probe is directly contacted with the pad of the wafer to be tested, thereby realizing the electrical performance test of the dies of wafer.

Tungsten wafer probe is specifically designed for wafer testing during the production of integrated circuit. Wherein, wafer testing is to test each die on the chip. In the general, a probe made of tungsten material is mounted on the detection head, and contacts the contacts on the dies to test their electrical characteristics. Unqualified dies will be marked. Then, when the chip is cut into individual dies, these unqualified dies marked will be eliminated, and the next process will not be carried out, so as not to increase the manufacturing cost.

Tungsten rubber, also known as polymer tungsten, is a newly developed material and is a lead-free radiation shielding material to replace lead radiation shielding material. Polymer tungsten can be made into various shields for radiation protection of medical equipment and medical personnel.

Tungsten resin is an emerging radiation shielding product made of tungsten powder and various polymers. It has many unique properties such as high density, corrosion resistance, anti-radiation, softness, and easy processing. Also, tungsten resin is non-toxic, environmental friendly, waterproof and long lasting. Therefore, it becomes the main substitute for lead. And it is mainly used to manufacture protective clothing and other medical protective products.

Polymer tungsten radiation shielding is a radiation shielding product made of polymer tungsten - a combination of tungsten particles and resin. It may be a piece of medical polymer tungsten protective clothing, or a protective skirt, etc. And it may be a shielding product used in medical devices.

Polymer tungsten sheet is made using non-toxic tungsten powder and natural rubber as raw materials, so it has high density and good shielding performance against various types of radiation. In other words, polymer tungsten retains the characteristics of lead, but it is not toxic, protecting you from different rays of radiation for medical diagnosis and treatment.

Polymer tungsten foil is an emerging material made of tungsten powder and polymers such as rubber and resin, which is environmentally friendly and non-toxic. In other words, polymer tungsten combines the characteristics of different materials, so the foil fabricated using polymer tungsten as a raw material has advantages of high density (≥11.34 g/cm3), good radiation resistance, environmental protection, excellent corrosion resistance and high temperature performance. Also, such a foil is easy processing and free cutting.

Polymer tungsten protective clothing is new type of radiation protective clothing. You know, lead is a traditional radiation shielding material, which is highly toxic and will cause great harm to the human body and the environment. Therefore, the emergence of non-toxic and environmentally friendly polymer tungsten is considered a revolution in the history of radiation protection. And there is no doubt that polymer tungsten - a combination of tungsten and polymers, will be more and more widely used in medical industry to replace traditional lead radiation shielding materials. It means that polymer tungsten is a promising material for protecting doctors and patients from radiation.

In recent years, studies have shown that polymer tungsten, also called tungsten rubber or tungsten resin, is the best material for the production of radiation protection clothing, radiation protection skirts and other medical radiation protection products. Well, do you know what are the advantages of polymer tungsten? Or what make tungsten rubber the preferred material for medical protection products?

Polymer tungsten, also known as tungsten resin and tungsten rubber, is a product made by combining various resin materials with tungsten powder particles in different proportions. Wherein, tungsten accounts for 60% of the product volume, but the weight accounts for more than 96% of the entire product; the resin material can be polypropylene, polybutene, polyurethane, thermoplastic materials, etc.
