FPC manufacturing process tapes

Carrier film for electronic components such as FPC with different peeling strength.

Please select the product name :

	PET8420
	Carrier film for FPC
	Cellular phones
	Peeling strength is high before exposure to UV radiation but declines after exposure to UV radiation, allowing easy peeling. Integrating UV light irradiation: cured with 200 to 250 mJ/cm^2..
