Circuit board plant classification
When we turn on the keyboard of a general-purpose computer, we can see a soft film (flexible insulating substrate), printed with a silver white (silver paste) conductive pattern and a healthy figure. Because the universal screen stencil method to get it, so we call this printed circuit board PCB, flexible printed circuit board silver paste PCB. And we go to the computer city to see a variety of computer motherboards, graphics cards, network cards, modems, sound cards and home appliances on the printed circuit board is different.
The surface process of gold tin plate etc.
Hard soft board flex joint strength according to the sun
Single sided printed circuit graphics we call single-sided printed circuit board, double-sided printed circuit graphics, and then through the hole of the two sides of the metal interconnect printed circuit board, we call it double sided board.
It is used by the base paper (used in single) or glass cloth (commonly used in double-sided and multilayer prepreg), phenolic or epoxy resin, the surface of one or both sides stuck on copper clad laminated and solidified into the book again. This kind of PCB, circuit board cover copper sheet, we call it rigid plate. Then printed PCB, circuit board, we call it a rigid printed PCB, circuit board.
