HelioFab AG 7921 a high-brightness silver electroplating process for leadframe-based LED packages is said to consistently deposit highly reflective silver with measured GAM values around 2.0 over a current density window of 10 to 70ASD.
The bath produces a stable deposit over the standard 100 AH/L industry bath life metric. Deposit passes all standard testing for LED performance such as 1000-hour luminous decay as well as assembly functional testing for gold wire bond pull and die attach shear strength.
