Use automatic machine to mount the dice on the silvery epoxy, the wire bonding to connect chips on PCB. To make sure the quality, we implement one operator one auto machine and to specify higher pull force than industry spec.
According to customer design to tooling the reflector and do the ink printing on the surface, then, we process the epoxy to reflector. This kind of semi-epoxy reflector can be flexible for variety shape design or thin design to meet all kind of customer design requirments.
For LED product, the epoxy is a key factor for reliability. Dramatic variation in temperature might cause stress to LED defect, so, we designed the semi-epoxy reflector to assembly with PCB by hot press process for higher reliability request products. With years’ experience in developing semi-epoxy process, we can now produce very high reliability semi-epoxy products.
After reflector process & assembly, the LED display need to do 100% electrical test. The test items include: Open, Short, VF High/Low, IR, uneven (color/brightness), light leak & foreign particles to make sure the quality.
