| Main Application |
Information application products, remote control, telecommunication equipment, OA equipment, household appliance, medical instruments, measuring instruments, toys...etc. |
| 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. |
