PCB terminals are used in the Wire Connectors Terminal of printed circuit boards to become PCB Wire Connectors Terminal or PCB connectors for electrical connections, with no parts on the standard PCB top and often referred to as "Printed Wiring Board (PWB)".

The manufacturing principle of PCB Wire Connectors Terminal

When we open the keyboard of the general computer, we can see a soft film (flexible insulating substrate), with a conductive figure and a strong position figure with silver white (silver paste). Because the universal screen printing method can get this figure, we call this printed circuit board a flexible silver paste printed circuit board. And we go to the computer city to see all kinds of computer motherboards, graphics cards, network cards, modem, sound card and printed circuit boards on household appliances are different. The substrate used is made of paper base (commonly used on one side) or glass fabric (commonly used in both sides and multilayers), prepreg phenol aldehyde or epoxy resin, on the surface one side or two sides of the overlying copper book and then laminating and solidifying. The printed circuit board is called rigid plate.

Once printed circuit board is made, we call it rigid printed circuit board. One side has printed circuit graphics, we call one side printed circuit board, double side has printed circuit graphics, and then through the metallization of holes to form a printed circuit board with double-sided interconnection, which is called a double-sided board.

If a printed circuit board is used as an inner layer, two pieces of one side as outer layer or two double sides as inner layer and two single side as outer layer, the printed circuit board, which is interconnected through the positioning system and insulated bonding material and interconnected with the design requirements, becomes four and six layers of printed circuit board, also known as multi-layer. Printed circuit board. There are more than 100 layers of practical printed circuit boards.
