Printed Circuit Board Design and Layout with Fabrication Service

printed circuit board design:

With the rapid development of electronic technology, the demand for electronic products is getting higher and higher, more and more functions, although the chip integration is getting higher and higher, but the design requirements for the circuit board is getting higher and higher.

PCB design, also known as PCB layout, because the circuit board (also known as printed circuit board) in English called printed circuit board, abbreviated as PCB, PCB design is also called PCB design; circuit board design, from hand-drawn to the more Large-scale component library, powerful automatic routing and other functions, more and more convenient for our engineers to circuit board design work.

Whether it is single-sided, double-sided, multi-layer board design, before are designed with protel, and now useful PADS, Allegro and other designs.

Printed circuit board design is based on circuit schematic, circuit designers need to achieve the function. PCB design mainly refers to the layout design, need to consider the layout of external connections, the internal layout of the optimal layout of electronic components, metal wiring and through-hole layout optimization, electromagnetic protection, heat dissipation and other factors. Excellent layout design can save production costs, to achieve good circuit performance and thermal performance. Simple layout design can be achieved by hand, complex layout design need to use computer-aided design (CAD) to achieve.

PCB board technology, including computer-aided manufacturing processing technology, that is, CAD / CAM, as well as light painting technology. The following describes the computer-aided manufacturing processing technology:

Computer-aided manufacturing (CAM) is the process according to a variety of processes. The above mentioned process requirements, should be made in the light before the necessary preparatory work. Such as mirroring, solder mask expansion, process line, process box, line width adjustment, center hole, contour lines and other issues should be in CAM this process to complete. In particular, note that the user file spacing is too small, you must make the appropriate treatment. Because each factory's technological process and the technical level are not identical, must achieve the user the final request, must make the necessary adjustment in the production craft, satisfies.

PCB design, they often want to use automatic routing. Typically, the pure digital circuit board (especially the signal level is relatively low, the circuit density is relatively small) using automatic routing is no problem. However, when designing analog, mixed-signal, or high-speed circuit boards, there may be some problems with automated routing tools for wiring software, and may even cause serious circuit performance problems. In this technical topic, electronic enthusiasts network for everyone from the PCB basic knowledge, PCB design skills, PCB design examples and PCB design experience to discuss multi-angle display PCB technology.
