DOUBLE SIDED PCB, PTH PCB
Safe & Stable
As the name stated Double sided PCB or PTH PCB have two layer of conductive material. The Double sided PCBs are introduced in 1970 and it was used for size restriction or complex circuitry in electronics Industries. PTH Stands for "Plated Through Hole" the Electroplating introduced in PTH PCB to connect upper copper layer and bottom copper layer.
