14K Gold Samsung 3623 SMD

14K Gold is not a selling point only, also not just for ID and appearance.  The 2.5mm thick PCB with 1U immersion gold layer is a key to reduce defect rate. The ENIG Tech (Electroless Nicker / Immersion Gold) is an ungraded PCB processing mostly applied to high-precision product as such keyboard. When this tech is applied on automotive LED bulb, you can image that performance and quality.
