What is 德赢ac米兰官方合作伙伴 ?
德赢ac米兰官方合作伙伴 is adhesive tape 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, sapphire and so on.
德赢ac米兰官方合作伙伴 ?
德赢ac米兰官方合作伙伴 includes these materials.
- Base Polymer
- Oligomer
- Photo initiator
Structure before 德赢ac米兰官方合作伙伴
Only base polymer has polymerization structure. Oligomer is not reacted yet, and it has a fluidity. Due to the fluidity, it’s a strong adhesion before 德赢ac米兰官方合作伙伴.
Structure after 德赢ac米兰官方合作伙伴
With 德赢ac米兰官方合作伙伴, oligomers make cross -linked structure by the polymerization reaction.
Therefore, Adhesive becomes hard and loses adhesive strength.
What kind of UV wave length is required for 德赢ac米兰官方合作伙伴 ?
Continuous 250~360nm wave length is required for cure reaction of UV-Tape.
德赢ac米兰官方合作伙伴 (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 德赢ac米兰官方合作伙伴 is affected by the head in the UV machine.
High Pressure Mercury Lamp (Recommended)
Main wave length is 365nm same as 德赢ac米兰官方合作伙伴. 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 fluorescent light, hence illumination intensity is lower than other lamp.

德赢ac米兰官方合作伙伴 ?
德赢ac米兰官方合作伙伴 UV-TAPE differ by tape grade, kind of UV lamp, and wafer surface conditions.
Regarding our UV-TAPE, recommendation UV irradiation is mentioned in our data sheet. Please examine 德赢ac米兰官方合作伙伴 irradiation condition referring to them.
德赢ac米兰官方合作伙伴 can be calculated by as follows:
Dosage of UV（mJ/cm2）=Illumination（mW/cm2） x time (sec.)
