Product Description

 1. Introduction to PCB Design:

With the advent of the 5G era, PCB is an indispensable electronic product in our lives. People are becoming more refined and intelligent in electronic products, and their functions are becoming more and more powerful. Although the integration of chips is becoming more and more strict, the design requirements for circuit boards are also getting higher and higher, and PCB design is particularly important, which is related to the assembly and service life of electronic products.


Circuit board design, also called PCB design, because the full name of the circuit board (also called printed circuit board) in English is Printed circuit board, abbreviated as PCB, so the circuit board design is also called PCB design; circuit board design, from hand-drawing to more Large-scale component library, powerful automatic layout and routing and other functions make it more and more convenient for our engineers to design circuit boards.

The JBpcb R&D and design team comes from the fields of communication, smart equipment, and smart home design, and has rich design experience. Professionally committed to providing customers with related services of electronic product customization, providing complete one-stop service of PCB R&D design and PCBA processing.

 The PCB is based on the circuit schematic diagram to realize the functions required by the circuit designer. The design of the PCB mainly refers to the circuit diagram design, which needs to consider various factors such as the layout of external connections, the optimal layout of internal electronic components, the optimal layout of metal connections and via, electromagnetic protection, and heat dissipation. Excellent circuit diagram design can save production costs and achieve good circuit performance and heat dissipation performance. Simple circuit diagram design can be realized by hand, and complex circuit diagram design needs to be realized with the help of computer-aided design.


 PCB design technology, including computer-aided manufacturing processing technology, namely CAD/CAM350, and light-painting technology. The following introduces the simple computer-aided manufacturing processing technology.

 Computer-aided manufacturing (CAM350) is to carry out various processing according to the specified process. For the various process requirements mentioned above, necessary preparations must be made before light painting. For example, mirroring, solder mask expansion, process line, process frame, line width adjustment, center hole, outline, and other issues must be completed in the CAM350 process. Special attention should be paid to the places where the spacing is too small in the user file, and corresponding treatment must be made. Because the process flow and technical level of each factory are different, to meet the final requirements of users, necessary adjustments must be made in the production process to meet the requirements of users in terms of precision and other aspects. Therefore, CAM350 processing is an essential process in modern printed circuit manufacturing.
