PCB News - Factors of PCB quality and electronic equipment

1. Factors that determine the quality of PCB
   Through the above introduction, I believe that everyone has a certain understanding of the PCB production process. You may think that the quality of products produced through similar processes should be consistent, but it is not.

   

   
   

First of all, the rationality of the documents of the PCB designer is a factor that determines the quality of the PCB. The PCB designer should be evenly distributed and arranged neatly when designing the PCB, meeting the process requirements of the PCB board, and considering the thermochemical reaction, so that the file is The factory can not be significantly modified by the factory, so as not to affect the performance of the product.
Secondly, the PCB factory should keep the board neat and clean when processing GERBER files, try to make the copper exposed reasonably, the characters clear, the lines are soft, and the craftsmanship is correct.
In addition, the PCB factory should consider the subsequent insertion process may affect the PCB when processing the PCB; the most common in the industry is the impact of the quality of the PCB ink on the appearance of the PCB. If the quality of a PCB is not well controlled during production, the color of the ink will be different after the insertion is completed, and the distribution of the ink will also be uneven.
Also, PCB warpage, PCB brightness, overall beauty, etc. are all things consumers should consider when choosing a board.

2. Growing soil for PCB electronic equipment
PCB is the abbreviation of Printed Circuit Board in English. Generally, conductive patterns made of printed circuits, printed elements, or a combination of both on insulating materials according to a predetermined design are called printed circuits. The conductive pattern that provides electrical connections between components on an insulating substrate is called a printed circuit. In this way, the printed circuit or printed circuit finished board is called a printed circuit board (PWB), also known as a printed board or printed circuit board (PCB).

PCB is the material basis for carrying integrated circuits, and almost all electronic devices we can see are inseparable from it. From electronic watches and calculators to computers and military weapon systems, as long as there are electronic components such as integrated circuits, PCBs are used for electrical interconnection between them. It provides mechanical support for the fixed assembly of integrated circuits and other components, realizes wiring and electrical connection or electrical insulation between various electronic components, provides required electrical characteristics, such as characteristic impedance, etc., and provides solder mask for automatic soldering Graphics; provide identifying characters and graphics for component insertion, inspection, and maintenance.
