Silver Through Hole PCB with carbon

This remote control circuit board is a single-sided PCB of the hole filling process, but it can achieve the same effect as the double-sided PCB through the hole filling process. By pouring silver paste into the holes between the two sides of the circuit board, the purpose of connecting the two sides of the circuit is achieved, and the oxidation resistance of the circuit board produced by the silver filling process isDifferent with the common technology,the manufacturing process calld Silver Through Hole could achieve the same conduction purpose as Plated Through Hole.Squeezing the silver paste into the hole by screen printing,silver paste could be attached to hole wall after baking,then the holes able to connect two sides.Because of the low cost and environmental protection,Silver Through Hole was widely used in home appliance and dashboards these years.
