How is the PCBA board is made?
As long as we open the health of general computer disk can see PCBA board of a soft film (flexible insulating substrate), printed with silver (silver pulp) of conductive patterns and health.Because general screening method to get the graphics, so we call this kind of flexible printed circuit board is for silver paste printing PCBA board.
And let's go to the computer city to see all kinds of computer motherboards, graphics CARDS, network CARDS, modems, sound card, and household appliance PCBA printed board is different.It the base material is used in this paper the base (often used in the single side) or glass cloth (often used for double-sided and multi-layer), presoak phenolic resin or epoxy resin, surface copper clad book on one side or two sides glued laminated curing.This kind of circuit board copper clad thin plate, we call it the rigid plate.Made of printed circuit board again, we'll call it the rigid printed PCBA board.
Some PCBA board is single-sided printed circuit patterns, we call it a single-sided printing PCBA board, double-sided printed circuit patterns, and then through the hole metallization of double-sided interconnection form of printed circuit board, we call it double panel.If using a double lining, two one-way for outer layer or two piece of double-sided printed as lining, two pieces of the single side as the outer PCBA board, through the positioning system and alternate insulation adhesive materials and conductive graphics interconnection according to design requirement of printed circuit board becomes four, six layer printed circuit board, also known as multilayer printed circuit board.Now has more than 100 practical printed circuit board
