1. Accurate and strict color matching according to customer's
requirement, both Panton and Ral color matching system, using
advanced light box and computer color matching, we can also do
2. Good material control to make sure all the material are high
quality, all the material we used are RoHS compliant
3. Our engineer will work with customers and recommend special
construction design to meet customer's desires, such water proof,
dust proof and anti corrosion and so on
4. Strict quality inspection, 100 % functional testing, and we can
also do specified testing, such as humility testing, life
expectancy testing, actuation force testing.
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 competitive price.
