PCB Classification Detailed Explanation
A. According to the product structure classification
Rigid Board (hardboard): Made of rigid substrate that is not easy to bend and has a certain degree of toughness, has the ability to resist bending, and can provide a certain degree of support for the electronic components attached to it. Rigid substrates include fiberglass cloth substrates, paper substrates, composite substrates, ceramic substrates, metal substrates, thermoplastic substrates, etc.
Flexible Board (flexible board): Printed circuit board made of flexible insulating substrate. It can be freely bent, coiled, folded, and can be arranged arbitrarily according to the requirements of the space layout, and in three-dimensional space, arbitrary movement and expansion, so as to achieve the integration of component assembly and wire connection.
Rigid-flex Combination Board: In a printed circuit board contains one or more rigid and flexible areas, the thin layer of flexible printed circuit board bottom layer and rigid printed circuit board bottom layer combined with lamination. The advantage is that it can provide the support of a rigid board, but also has the bending characteristics of a flexible board to meet the needs of three-dimensional assembly.
HDI Board: That is, high-density interconnect technology, is one of the printed circuit board technology, HDI boards are generally manufactured using the laminated method, the use of laser punching technology to punch holes in the layers of conduction, so that the entire printed circuit board formed to bury, blind holes for the main conduction mode of the inter-layer connection. Compared with traditional multilayer printed circuit boards, HDI boards can improve board wiring density, which is conducive to the use of advanced packaging technology; can make the signal output quality enhancement; can also make electronic products in the appearance of a more compact and convenient.
Packaging Substrate: That is, IC package loading board, directly used to carry the chip, the chip can provide electrical connection, protection, support, heat dissipation, assembly and other efficacy, in order to achieve multi-pin, reduce the size of the packaged product, improve the electrical properties and heat dissipation, ultra-high density or multi-chip modular purpose.
B. According to the number of layers of the circuit diagram classification
Single Panel: Printed on a substrate layer of conductive graphics, this plate is commonly used in simple electrical or electronic products.
Double-sided Board: Printed on the substrate on the front and back of the conductive graphics, this board is commonly used in electronic products that require double-sided wiring.
Multi-layer Plate: More than two layers of conductive graphics and insulating layer composed of the plate, this plate is commonly used in the need for high-density wiring of electronic products or special applications.
C. According to the application area classification
Communication Boards: Circuit boards used in communication equipment, such as cell phones, routers, switches, etc..
Consumer Electronics Boards: Circuit boards for consumer electronics, such as TVs, stereos, game consoles and so on.
Computer Boards: Circuit boards for computer hardware, such as motherboards, graphics cards, sound cards, etc.
Automotive Electronics Boards: Circuit boards for automotive electronic control systems, such as engine control modules, body control modules.
Military/aerospace Boards: Circuit boards for military and aerospace applications, such as missile control systems and satellite communication systems.
Industrial Control Boards: Circuit boards for industrial control and automation systems, such as PLC, DCS, etc.
Medical Boards: Circuit boards used in medical equipment, such as medical imaging equipment, monitors and so on.
D. According to the specific application of the end product classification
Cell phone Boards: Ircuit boards for cell phones, including motherboards, touch screen circuit boards.
Television Boards: Circuit boards for television sets, including motherboards, display driver circuit boards.
Boards for Audio Equipment: Circuit boards for audio equipment, including amplifier boards, speaker control boards, etc.
Electronic Toy Boards: Circuit boards for electronic toys, including game machine motherboards, remote control circuit boards, etc.
Camera Boards: Circuit boards for cameras, including motherboards, lens driver boards, etc.
LED Boards: Circuit boards for LED lighting and display devices, including LED driver boards, display control boards, etc.
Boards for Medical Ddevices: Circuit boards for medical devices, such as medical monitor motherboards, signal processing circuit boards for medical imaging equipment, etc.
