What is a circuit board

　　Printed Circuit Board, commonly known as PCB, is a complex manufacturing process that involves dozens of processes such as inner layer, pressing, and drilling. It is generally classified according to the number of layers and characteristics, and can be divided into three types based on the number of layers: single-layer board, double-layer board, and multi-layer board. Single panel refers to a circuit board where wires are concentrated on one side, Double panel refers to a circuit board with wires distributed on both sides, while multi-layer single refers to a circuit board with more than two sides.

　　Circuit board classification:

　　1. Flexible board

　　2. Rigid plate

　　3. Soft hard combination board

　　Circuit boards can be divided into three main categories based on their characteristics: flexible boards, rigid boards, and soft hard composite boards. Flexible boards, also known as FPCs, are mainly made of flexible substrate materials such as polyester film, which have the characteristics of high assembly density, lightweight and flexible bending. Rigid boards are generally referred to as PCBs, which are made of rigid substrate materials such as copper clad boards, and are currently the most widely used, Soft hard combination board, also known as FPCB, is manufactured by pressing and other processes between soft and hard boards, while also possessing the characteristics of PCB and FPC.

　　What is a circuit board

　　A circuit board usually refers to a circuit board that has SMT chip mounting or DIP plug-in installation of electronic components, which can achieve normal product functions. It is also known as PCBA, also known as Printed Circuit Board Assembly in English. There are generally two production methods for circuit boards, one is SMT chip mounting assembly process, and the other is DIP plug-in assembly process. The two production methods can also be combined. Okay, that's all the difference between a circuit board and a circuit board.
