There are various specifications and types of wafers. Here are some common wafer specifications and types: 1. Diameter: The diameter of a wafer is one of the most commonly used specifications. Common diameters include: - 200mm: also known as 8-inch wafers. - 300mm: also known as 12-inch wafers. - 150mm, 100mm, 75mm, 50mm, etc. 2. Thickness: The thickness of wafers is usually controlled and adjuste...

First, it takes 4 ~ 8min to start the high-pressure mercury lamp from the start to the stable operation of the lamp, and the photoelectric parameters change greatly during the start process. In addition, in a low temperature environment, the start of high-pressure mercury lamps will be more difficult, or even can not start. After the high-pressure mercury lamp is extinguished during work, it canno...

The DSXUVUV strength Meter 5800 series is widely used in various industries in the UV field. It offers multiple options for selecting different UV wavelengths and can measure real-time power, peak power, average power, minimum power, and energy value of UV light sources. It allows users to test different regions of UV light sources and evaluate their uniformity. The instrument is designed for simp...

Offset printing is one of the main printing methods, with the development of UVLED light curing technology, UVLED curing system gradually replaced the traditional UV curing, at present, there are also printing plants for offset printing press installed UVLED curing system. Why can UVLED curing system replace mercury lamp? The service life of mercury lamp is short, generally about 1000 hours. Mercu...

UV debonding, also known asaviolet (UV) debonding, is a technology based on UV irradiation and chemical reactions used for curing or debonding adhesives, coatings, inks, and other materials. The principle involves the use of a photoinitiator and UV irradiation. 1. Photoinitiator: A photoinitiator is a chemical substance that absorbs UV light and undergoes a chemical reaction, generating free radic...

A 12-inch manual Wafer Expander machine is a device used for expanding or stretching various materials. It is operated manually and features a 12-inch width, which determines the maximum size of the material it can accommodate. The machine is designed to provide controlled and uniform stretching to achieve desired results. Manual 12-inch wafer Expander manufacturer manufacturer:leduvcuring.com The...

Both the UV tape and blue film are viscous, and their viscosity is expressed by the viscous peel degree, usually N/20 mm or N/25 mm. For example, the meaning of 1 N/20 mm is that the width of the test strip is 20 mm, and the force to peel it off from the test version with a 180° peel Angle is 1 N. UV film is a special formulation of coating on the surface of PET film substrate, to achieve the effe...

Before the wafer is thinned, a sticky film is attached to the front of the wafer. The role of the film is to secure the chip on the front of the wafer, which is easy for the grinding machine to grind on the back of the wafer. Generally, the thickness of the silicon wafer before grinding is about 700 μm, and after grinding, the thickness of the wafer becomes 200 μm, or even 120 μm. The wafer thinni...
