Material
|
Polyester is used
for both circuit layers and overlay layers. High temp and corrosion resistant, the
flexibility and mechanism are good as well as high reliability. It is mostly
suitable used in products where the application environment are atrocious
or products are emboss required.
|
Polycarbonate is
usually used for overlays. It has more competitive price than PET so mostly
used in products that styles improved frequently, such as microwave
oven and toys , etc.
