Substrate coating, e.g. under LEDs

White solder resists  ELPEMER®

• optimises the light emission of LEDs, very high reflectivity of the substrate through application of a „neutral“ white opaque solder mask (colour of white LEDs is not falsified)

• pure white colour even after lead-free reflow, soldering and tempering processes

• also for flexible application

 

Black solder resists ELPEMER®

• minimum light reflection from the substrate by using a black solder resist

• increased contrast to the LED

• also for flexible applications
