- What is PCB?
PCB is an important electronic component, the support of electronic components, and the carrier for the electrical interconnection of electronic components. Due to its use of electronic printing technology, it is called a printed circuit board. - A Brief History of PCB Development
The creator of the PCB is Austrian Paul Eisler, who first used printed circuit boards in radios in 1936. In 1943, Americans mostly applied this technology to military radios, and in 1948, the United States officially recognized the invention for commercial use. Printed circuit boards have only been widely used since the mid-1950s. Printed circuit boards appear in almost every type of electronic device. If there are electronic parts in a certain device, they are also embedded on PCB boards of different sizes. The main function of a PCB is to connect various electronic components into predetermined circuits, playing a relay transmission role. It is a key electronic interconnection component of electronic products and is known as the “mother of electronic products”. - Classification of PCB
Classified By Material: organic materials (phenolic resin, glass fiber/epoxy resin, polyimide, BT/Epoxy), inorganic materials: (aluminum, MCPCB, ceramic)
Divided By Structure: single panel, double-sided panel, multi-layer panel
Hardness Performance: hard board, soft board, soft hard combination board
Conduction Status Of Holes: buried hole plate, blind hole plate, through hole plate
Surface Production: spray tin plate, gold-plated plate, sinking gold plate, gold finger plate, sinking tin plate, sinking silver plate - What are the characteristics of a PCB？
High-density High reliability
Designability Producibility
Testability Assemblability Maintainability - What is the function of a PCB？
(1) Provide mechanical support for fixing and assembling various electronic components such as integrated circuits, achieve wiring and electrical connections or insulation between various electronic components such as integrated circuits, and provide the required electrical characteristics.
(2) Provide solder mask graphics for automatic welding, and identification characters and graphics for component insertion, inspection, and maintenance.
(3) After using printed boards in electronic equipment, due to the consistency of similar printed boards, manual wiring errors are avoided, and electronic components can be automatically inserted or pasted, soldered, and inspected, ensuring the quality of electronic products, improving labor productivity, reducing costs, and facilitating maintenance.
(4) Provide the required electrical characteristics, characteristic impedance, and electromagnetic compatibility characteristics for circuits in high-speed or high-frequency circuits.
(5) The printed circuit board with embedded passive components provides certain electrical functions, simplifies electronic installation procedures, and improves product reliability.
(6) In large-scale and ultra large-scale electronic packaging components,it provides an effective chip carrier for miniaturized chip packaging of electronic components.
- What is PCBA？
PCBA is a Printed Circuit Board Assembly,which means that PCBA passes through the entire process of PCB empty board SMT loading,followed by DIP plugins. - What is the difference between PCB and PCBA？
PCBA generally refers to a processing process,which can also be understood as a finished circuit board.PCBA can only be calculated after all the processes on the PCB board are completed.PCB refers to an empty printed circuit board with no parts on it.PCBA is a finished board,while PCB is a bare board. - Why choose MEKCO and what are our strengths？
