What is the difference between a circuit board and a circuit board? In life, many people confuse circuit boards with circuit boards. In fact, the difference between the two is relatively large. Generally speaking, circuit boards refer to bare PCBs, that is, printed boards without any components mounted on them. The circuit board refers to the printed board that has been mounted with electronic components and can realize normal functions. They can also be understood as the difference between the substrate and the finished board!
The circuit board is usually called PCB, and its full name in English is: Printed Circuit Board. According to the characteristics, it can be divided into three types: single-layer board, double-layer board and multi-layer board. The single-layer board refers to the circuit board with the wires concentrated on one side, and the double-side board refers to the circuit board with wires distributed on both sides. The multi-layer single refers to the circuit board with more than two sides;
Circuit boards can be divided into three main categories according to their characteristics: flexible boards, rigid boards, and soft-rigid boards. Among them, flexible boards are referred to as FPCs, which are mainly made of flexible substrate materials such as polyester films. It has the characteristics of high assembly density, light and thin, and can be bent. Rigid boards are generally referred to as PCBs. They are made of rigid substrate materials such as copper-clad laminates. They are currently the most widely used. Rigid-flex boards are also called FPCBs. It is made of soft board and hard board through lamination and other processes, and has the characteristics of both PCB and FPC.
The circuit board usually refers to the circuit board with SMT patch mounting or DIP plug-in plug-in electronic components, which can realize normal product functions. It is also called PCBA, and the full English name is Printed Circuit Board Assembly. There are generally two production methods, one is the SMT chip assembly process, the other is the DIP plug-in assembly process, and the two production methods can also be used in combination. Well, the above is the whole content of the difference between the circuit board and the circuit board.
