The classification of CB is basically divided in two forms: one is based on the product structure, and the other is based on product purposes.
According to the product structure, the first is the three categories: rigid board (RPCB), deflection board (FPCB), and rigid binding board (R-FPCB). , Multi -layer (MLB). Generally, the single, double -sided, and multi -layer boards are usually rigid when not indicating. Due to the small output ratio, the rigid binding board is attributed to the scratch plate. Further subdivision, in addition to the traditional single -sided, double -sided, and multi -layer boards, there are high -density interconnection (HDI) boards, metal base (core) boards, buried component boards, and so on.
According to the product use, the PCB is used in which terminal device is called what board. If it is used for a computer, it is called a computer board. It is called a car board for a car. , Computer storage board and so on. The IC packaging board is known as the purpose of PCB. According to the distinction between the PCB structure and the use of use, the two can reflect the characteristics of PCB and reflect the technical level compared to the structure.
According to the division of use, the use of PCB does not necessarily reflect its performance requirements. For example, the performance requirements for PCB in different parts of the car are very different. Therefore, the classification of PCB is different from the product structure, and the PCB product standards are also more accurate in structure types.
In addition, some are incorrectly tied with PCB with FPCB, or PCB and IC packaging boards are not appropriate. Printing circuit board (PCB) is a general name that the flexible board (FPCB) and IC packaging board are just one of them. I hope everyone can clarify the relationship and avoid misunderstanding.
