Part Number	AS-20
Use Application	Top cover tape for embossed carrier tape
Feature	Stable sealing strength Good sealing strength with long time stability over different carrier tapes made of PS, A-PET, and PC. It can seal with low temperature and therefore can avoid heat deformation of the carrier tapes.
	Good transparency Good transparency with low haze. It can offer efficiency improvement especially for quality control.
	Antistatic property It has an antistatic structure in the middle layer with special coating and avoids static charge with peeling and abrasion and then can control the jumping problem and the static error on semiconductor components.
	Superb mechanical strength Good strength to be applicable for high-speed assembly.
