Knowledge that purchasers must know about printed circuit boards !

As we all know,the printed circuit boards used in actual electronic products vary widely. However, according to different types,

printed circuit boards have different classifications, details are as following

1  according to the layer count of  printed circuit boards

• Single-sided PCBs

single layer PCB is a printed circuit board that has only one layer of circuit and one layer of solder mask, and normally,  the substrate of single layer PCB

has thickness of 0.2 mm-5 mm, single layer PCBs are simple to manufacture, easy to assemble,suitable for electronic products with a single circuit

such as radio, TV, etc. Besides, single layer PCBs are not suitable for applications requiring high assembly density or complex circuits

 

• Double-sided PCBs

Double layer PCBs are a printed circuit board that has two layers of circuit and  solder mask, usually, it’s top layer and bottom layer on both sides of PCBs

In addition, double-sided PCBs are suitable for general requirements of electronic products such as electronic computers, electronic instruments and meters

Since the wiring density of double-sided PCBs is higher than that of the single-sided PCBs, the volume of the electronic device can be reduced

 

 

• Multilayer PCBs 

Multilayer PCBs are a printed board on which three or more printed circuits are printed on an insulating substrate

 

2  according to the nature of the substrate 

According to the nature of the substrate, the printed circuit board can be divided into three types: rigid PCB , FPC and rigid-flex PCB

Rigid PCBs

The rigid printed board has a certain mechanical strength, and the parts it is assembled have a flat state.

And, rigid printed circuit boards are used in general electronic products,common circuit boards are generally rigid printed circuit boards

 

Flexible PCBs/FPC

What’s more, the flexible printed board is characterized by its ability to be bent, curled, folded, and can be connected to rigid printed boards and moving parts,

Besides, it is small in size, light in weight, easy to assemble, and suitable for space. Small, high-density electronics

Suitable for electronic products with small space and high assembly density

 

Rigid-flex PCBs

Rigid-flex printed circuit board is a printed circuit board that has rigid pcb and FPC, like the following picture :
