Printed Circuit Board (PCB), also known as Printed Circuit Board, is an important electronic component, a support body for electronic components, and a carrier for electrical connection of electronic components.Because it is made by electronic printing, it is called “printed” circuit board.
PCB or printed circuit board is the traditional name for bare board, you provide our layout data and use it to install your components once we deliver them to you.
Printed circuit boards, or PCBS, are used to mechanically support and electrically connect electronic components using conductive paths, tracks or signal traces etched from the copper sheet laminated to a non-conductive substrate.
A circuit board is more accurately referred to as a printed circuit board (PWB) or etching circuit board when it has only copper tracks and features and no circuit elements such as capacitors, resistors, or active components are manufactured on the actual circuit board.
Today, all but the simplest commercially produced electronic devices use printed wiring (circuit) boards and allow for fully automated assembly processes that were impossible or impractical in the early label-type circuit assembly process.
PCBS made up of electronic components are called printed circuit board assemblies (PCA), printed circuit board assemblies, or PCB assemblies (PCBA).In informal use, the term “PCB” is used for both bare and assembled boards, and its context illustrates what it means.IPC’s preferred term for a filler board is CCA, or circuit board assembly.This does not apply to the backplane;The assembled backplane is called the IPC backplane component.
Electronic equipment with printed board, because of the same kind of printed board consistency, so as to avoid manual wiring errors, and electronic components can be automatically inserted or pasted, automatic soldering, automatic detection, ensure the quality of electronic equipment, improve labor productivity, reduce costs, and facilitate maintenance.
The advantage of the PCB
The invention of printed circuit boards was one of the factors that made electronic circuits smaller, more compact and contained on a convenient, sturdy circuit board.By drilling holes in the circuit board, components such as resistors and capacitors can be inserted and welded automatically.
PCBS are everywhere
Today, almost every appliance in your home has a printed circuit board of some kind: a computer, a printer, a television, a stereo, a musical instrument amplifier and synthesizer, an electronic clock, a microwave oven, a telephone answering machine, even a cell phone.
PCB board in computer
The “motherboard” in the computer is the core of the computer, is the main printed circuit board.Other circuit boards inside the computer perform functions such as RAM(random access memory), power, modems, and video “CARDS.”
PCB can be more and more widely used, because it has many unique advantages, as follows:
1. High density.
For decades, with high density PCB can enhance integrated electricity e799bee5baa6e997aee7ad94e78988e69d8331333431346432 road integration and installation of technical progress and development.
2. High reliability.
Through a series of inspections, tests, and aging tests, the PCB is guaranteed to work reliably over a long period of time (typically 20 years).
PCB performance (electrical, physical, chemical, mechanical, etc.) requirements, can be through design standardization, standardization, etc. to achieve PCB design, short time, high efficiency.
Adopt the modern management, can carry on the standardization, the scale (the quantity), the automation production, guarantees the product quality consistency.
A more complete test method, test standard, various test equipment and instruments are established to test and identify the PCB products’ eligibility and service life.
PCB products not only facilitate the standardized assembly of various components, but also can be automated, large-scale production.At the same time, PCB and various components assembly components can also be assembled into larger parts, systems, and the whole machine.
Because PCB products and component assemblies are designed and manufactured on a standardized scale, they are also standardized.So, once the system failure, can be quickly, convenient, flexible to replace, quickly restore the service system.Of course, there are more examples.Such as the system miniaturization, lightweight, high-speed signal transmission and so on.
The above is the introduction of what PCB board is used to do;We are a PCB prototype manufacturing plant in China, products: pcb gold fingers, copper clad board pcb, metal pcb, etc., welcome to consult ~
