Many important parameters of electronic devices are closely related to the resistivity and the uniformity of its distribution, such as the reverse saturation current of the diode, the saturation voltage drop of the transistor and the magnification β, etc., which are directly related to the resistivity of silicon single crystal. Therefore, the resistivity test of devices has become an important process in chip processing, and its uniformity control and accurate measurement are directly related to whether power devices with better performance can be manufactured in the future.

With the rapid development of the mobile communication industry, 5G has now become a super hot topic of global attention, compared with 2G, 3G and 4G, the future fiber optic communication industry 5G status should not be underestimated, in the era of 5G network, no matter what kind of 5G bearing solution is inseparable from the 5G communication optical module. Diversified standards of 5G communication optical module is now considered the core technology of the next generation of high-speed rate and high-capacity optical network.

How to reduce costs and increase efficiency for your testing?

With the recent outbreak of influenza A, all kinds of thermometers have once again become an essential item for home health monitoring. The core component of the electronic thermometer commonly used at present is the temperature sensor. The working principle of the thermal sensor is to use the radiant heat effect to cause the temperature of the detection device to rise after receiving radiant energy, thereby changing the performance of the column and temperature in the sensor. By detecting a change in one of these properties, radiation can be detected. In most cases, when the device receives radiation, it causes a non-electrical physical change, and then changes it into electric quantity through appropriate changes for measurement.

To achieve an efficient and large-scale automated production mode in the manufacturing industry, a reliable, stable and efficient ATE test system needs to be used on the production line. Among them, the burn-in test system is a very common type of ATE in the electronics industry. Whether it is a component, a component, a whole machine or an equipment, aging test is required. On the one hand, it can predict the life of the product, and at the same time, it can also promote the early exposure of various potential defects hidden in the product, so as to achieve the purpose of early rejection of failed products.

A starter motor, also called a starter motor, is a motor used to start a diesel or gasoline engine. The starter motor can effectively reduce the trouble of manpower starting the engine, start more quickly, and can be used repeatedly. It is often used for starting automobile engines, starting generators, and starting large-scale construction machinery.
