Many low-priced silver contacts use "electroplating" or "coating" processes, resulting in extremely thin silver layers that are prone to detachment during stamping, or causing periodic device burnout when the current is too high.
DONGGUAN INT METAL TECH CO LTD adopts the cold pressing composite (cold heading) process, which combines silver or silver alloy with copper in the solid state through tremendous pressure. This process ensures uniform thickness of the silver layer and extremely high bonding strength, the silver contacts produced by INT METAL can guarantee the lifetime reliability of customer products.
