PCB=printed circuit board; The Chinese name is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.
What is PCBA?
PCBA=assembly of PCB. Various electronic devices are assembled on the circuit board through the surface packaging process. Next is the box assembly, which is about assembling the assembled PCB with the housing to form a finished product. That is to say, the empty PCB board goes through the SMT loading, and then goes through the entire manufacturing process of the DIP plug-in, referred to as PCBA. This is a common way of writing in China, while the standard way of writing in Europe and America is PCB'A, with an oblique dot added. PCBA is a PCB with a patch on it.
PCB is what we call circuit board circuit board, and the PCB drawing is processed into circuit board circuit board called PCB. After SMT (mounting) on the empty PCB board, the components required for the board are pasted, called PCBA. The board with the components already pasted, only needs to assemble the shell, debug the program, and a complete electronic product is completed.
According to the survey, many small and medium-sized electronic product manufacturers have to contact the patch manufacturers after purchasing PCBs. More and more electronic product manufacturers will choose to allow PCB manufacturers to process patches at the same time as PCBs, or to allow patch manufacturers to purchase PCBs instead. In these two modes, electronic product manufacturers can directly assemble and use the circuit boards they have to produce finished products. Many manufacturers that can only produce PCB, unconditionally process PCBA on behalf of them, will lose customers who need to be processed at the same time. Such customers choose manufacturers who have the ability to add at the same time, or choose a placement factory to let the placement factory purchase PCB on its behalf. Many people may ask why the patch factory can purchase PCB, and why the PCB factory does not contact the patch factory. It is a very simple matter for SMT manufacturers to purchase PCBs. They only need to ask customers to provide production drawings and production processes. Moreover, the PCB market price is very transparent and easy to purchase. However, PCB manufacturers do not understand the products and prices of various components. It is difficult to contact the patch factory for patch production, and only focus on the production of PCBs.
In recent years, PCB manufacturers have gradually expanded their factories and increased PCBA generation processing lines while producing PCBs. This one-step approach has been recognized by many electronic product manufacturers. This method of contemporary processing has both advantages and disadvantages. The profit margin of the contract factory has increased, but the risks are also increasing at the same time. The main reason is that each electronic product needs different components to purchase components for customers. Even if the same product has different design drawings, the components used are different. If the type of components purchased is wrong, the board and components will be scrapped at the same time. It is also difficult to estimate the direct economic losses. The increase in manpower and material resources is also inevitable. Under the pressure of market competition, simultaneous processing of PCB and PCBA is also inevitable.
