The challenge
High Brightness LEDs were experiencing silver reflector corrosion, which was leading to decreased light output, increased heat build-up and reduced product lifetime. The traditional methods for LED packaging were not good enough to prevent the corrosion.
The customer
A leading LED manufacturer.
Beneq solution
ALD was used to coat the semi-finished wire-bonded LED assemblies before sealing the package to protect the silver surface with an nSILVER-type ALD coating.
