Advantage:

1. Accurate and strick color matching according to customer's requirement, both Panton and Ral color matching system, using advanced light box and computer color mataching, we can also do half-tone printing

2. Good material control to make sure all the material are high quality, all the material we used are Rohns compliant

3. Our engineer will work with customers and reommend specail constrution design to meet customer's desires, such water proof, dust proof and anti corrasion and so on

4. Strick quality inspection, 100 % funtional tesiting, and we can also do specified testing, such as humility testing, life expectancy testing, actuation force testing.

5. We are qualified Dara switch. 5. Except membrane switch and touch screen, we can also do different types of assembly, such as membrane switch and touch screen with FPC, PCB, silicone rubber, metal backer, plastic bezel and so on.

6. We can accept small quantity order and offer competitve price.
