Thin PCB circuit board
Product description
PCB circuit board is the carrier of components and one of the most important hardware of various electronic equipment. All kinds of electronic equipment can only operate through PCB circuit boards and various components carried by them.
Thin and hard PCB circuit boards are more and more widely used in the electronic field because of their thickness, lightness, lower price than FPC soft boards, and no need for reinforcement support when patching.
