What is UV 遊雅堂 入金 キャンセル ?
UV 遊雅堂 入金 キャンセル is adhesive 遊雅堂 入金 キャンセル for semiconductor process. It is suitable to protect surface of semiconductor wafer during backgrinding process, and to hold semiconductor wafer with ring frame during dicing process.
It is also applicable for various workpieces such as ceramics, glass, sapphi遊雅堂 入金 キャンセル and so on.
What is mechanism of UV cu遊雅堂 入金 キャンセル 遊雅堂 入金 キャンセルaction ?
UV 遊雅堂 入金 キャンセル includes these materials.
- Base Polymer
- Oligomer
- Photo initiator

What kind of UV wave length is required for UV 遊雅堂 入金 キャンセル ?
Continuous 250~360nm wave length is required for cure reaction of UV-遊雅堂 入金 キャンセル.
Me遊雅堂 入金 キャンセルl-halide Lamp (Recommended)
Main wave length is 365nm.
However that, this lamp also have 250~450nm wave length, widely.
Too many UV irradiation is not recommended because UV 遊雅堂 入金 キャンセル is affected by the head in the UV machine.
High P遊雅堂 入金 キャンセルssu遊雅堂 入金 キャンセル Mercury Lamp (遊雅堂 入金 キャンセルcommended)
Main wave length is 365nm same as Me遊雅堂 入金 キャンセルl-halide lamp. Others efficient wave length are 254nm, 303nm, 405nm and 436nm.
Black Light
Peak wave length is 360nm and its range is 300~400nm.
On the other hand, black light is fluo遊雅堂 入金 キャンセルscent light, hence illumination intensity is lower than other lamp.

The most suitable UV condition for UV-遊雅堂 入金 キャンセル ?
The most suitable UV condition for UV-遊雅堂 入金 キャンセル differ by 遊雅堂 入金 キャンセル grade, kind of UV lamp, and wafer surface conditions.
Regarding our UV-遊雅堂 入金 キャンセル, recommendation UV irradiation is mentioned in our data sheet. Please examine the most suitable irradiation condition referring to them.
UV irradiation can be calculated by as follows:
Dosage of UV（mJ/cm2）=Illumination（mW/cm2） x time (sec.)
