There are three American EIT energy meters that have undergone the latest calibration by the original factory. One is the POWER PUCK for measuring mercury lamps, one is for measuring 395nm for LEDs, and the other is for measuring the 405nm band. So let's put these three meters in the mercury lamp at the same time, in the same position, for time and speed, and compare the data. As shown in the figu...

1、 Principle of UV glue remover UV glue remover is a fully automated equipment for reducing and releasing the viscosity of UV film and cutting film tape. In the semiconductor chip production process, before chip cutting, the wafer is fixed on the frame with a cutting adhesive film. After the cutting process is completed, the fixing adhesive film is irradiated with UV light to solidify and harden t...

When UV varnish passes through the irradiation area of UVLED curing equipment, the best temperature should be 50-60, because at this temperature, UV varnish cures fast and has strong adhesion after curing.In addition to the choice of UVLED curing equipment affecting UV varnish curing, some varnish itself or operational issues will also have an impact: Scratch resistance: The scratch resistance of ...

Dummy Wafer Dummy means fake, not real. Generally, there are no graphics, or only a few layers of graphics. Main application for: 1.It is used for commissioning and calibration of semiconductor equipment to ensure that the equipment is in the best condition before the official production. 2. When introducing a new process or adjusting an existing process, dummy wafer chips are used for testing and...

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...
