Classification of pcb

PCB (Printed Circuit Board), also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printing" circuit board.PCB board is mainly considered material and thickness, etc. And color is rarely considered. Soldering inks are available in white, yellow, black, red, and blue, as well as a clear ink. The most used is green ink. The solder mask ink used according to the accuracy requirements of the board is different.

PCB boards have the following three main types of division:Single-Sided Boards,Double-Sided Boards,MultI-Layer Boards

If it is divided by materials, it can be divided into organic materials and inorganic materials.Organic material including phenolic resin, glass fiber / epoxy resin,polyimide, BT / Epoxy, etc.these are all belong to it.Inorganic material including aluminum, copper-invar-copper, ceramic, etc. belong to it.
