Flexible printed circuit boards can be divided into one-sided, two-sided and multi-layer boards. Polyimide copper clad laminates are the main substrates used. This material has high heat resistance, good dimensional stability, and the final product is made by pressing the covering film with both mechanical protection and good electrical insulation. Polyimide resin is a kind of heat-resistant resin with five negative rings of imide, which is represented by polyphenylenetetraacid produced by the reaction of oxygen-containing layer group and anhydrous phenylenetetraacid. The conductors used in flexible printed circuit boards are thin foil copper, which is called copper foil. Its manufacturing methods can be divided into electrolytic copper foil and calendered copper foil, in which calendered copper foil is the mainstream. In addition, the surface and inner conductors of double-sided and multi-layer printed circuit boards are metallized to realize the electrical connection between the inner and outer circuit layers.usb-c cable M12 adapter vacuum bipolar RF socket
