Photoresist (lithium battery coating series)

Product Description

Photoresist is a key semiconductor material, in which photosensitive dry film is the core category of photoresist.
The photosensitive dry film is made by evenly coating the pre-prepared photoresist on polyester film (PET film) by a precision coating machine in a highly clean environment. After drying, cooling, and then coated with a layer of polyethylene film (PE film), and finally rolled into a film type photoresist.
Photosensitive dry film is the core raw material in PCB (printed circuit board) manufacturing, which has a direct impact on processing accuracy.
Photosensitive dry film is generally composed of three layers: polyethylene film (PE), photoresist film (sensitive layer) and polyester film (PET).
The polyester film is the carrier of the photosensitive material, which is used to assist the photosensitive material to evenly coat and form a film.
Photosensitive dry film plays a key role in the production of PCB boards in aerospace science and technology, computers, medical equipment, consumer electronics, automotive electronics and other fields.
