MetalcorePCB​ manufacturer  talk Printed circuit is a conductive pattern attached to the insulating substrate surface to connect electronic components.  The finished boards of printed circuit become printed circuit boards, namely PCBs.

 

 

Classification of PCB

1. Rigid PCB: The rigid PCB has a certain mechanical strength, and the parts installed with it have a certain ability of resistance to bending, and it is usually at a state of flat when used.Generally, the rigid PCBs are always popular with the electronic devices because of its good flatness and excellent performance of resistance to bending.

 

 

2. Flexible PCB: Flexible PCBs(FPC) are made of soft laminated plastics or other soft insulating materials.The boards made by the flexible PCBs can easily be bent and stretched, which means that people can bend optionally them when using the flexible PCBs according to the installation requirements.Flexible printing plate is used for special occasions.For example, the display screen of some digital multimeter can be rotated just because of the popularity and application of the flexible PCBs.

 

 

3. Single-side PCB: Single sided PCB is the basic simple PCB, parts is layouted on one side and the circuit is on the other side.As there is only layer conductor, it is called single sided PCB (Single-sided PCB or one layer PCB).Single-side PCB is usually made of the laminate or the glass cloth and the conductive pattern of it is relatively simple, so most of them are made by silkscreen printing or wet film process.In addition, some small amount of various products usually use photoresist to pattern circuit.

 

 

4. Double-side PCB: Double Sided PCBs (also known as Double-Sided Plated Thru or DSPT, which is usually made of the epoxy board or the glass cloth.) circuits are the gateway to higher technology applications.They allow for closer (and perhaps more) routing traces by alternating between a top and bottom layer using vias.

 

 

5. Multi-layer PCB: A multilayer PCB is a printed circuit board with three or more layers of conductive graphics.The conductive graphic of the inner layer of the multi-layer board is superimposed with the insulating bonding sheet, and the outer layers are covered with foils, which are compressed into a whole multi-layer board.The holes of multi-layer board must be metallized in order to lead out and connect the printed circuits sandwiched between the insulating substrates, which is also namely PTH (Plate Through Hole).
