For engineers in HDI factory, Layout is the art of hardware

PCB manufacturers, PCB designers and PCBA manufacturers explain that for HDI engineers, Layout is the art of hardware

The design of printed circuit board is based on the circuit schematIC diagram to realize the functions required by the circuit designer. The design of printed circuit board mainly refers to layout design, which needs to consider the layout of external connections. The optimal layout of internal electronIC components, the optimal layout of metal wiring and through-hole, electromagnetic protection, heat dissipation and other factors. Excellent layout design can save production costs and achieve good circuit performance and heat dissipation.

Layout is a thing that the process is sometiMES happy and sometimes painful, but the result is absolutely enjoyable. For every HDI factory who pays attention to Layout, in the end, they can always get incomparable satisfaction and sense of achievement from the results!

Sometimes we are used to making a good game in 99se directly, and then we will make A+A+R. Then they can modify it randomly and send it out to do it. At that time, I thought that Layout was just a tedious process that could not be ignored.

Later, I learned that for all complex communication and server products, there are always two or three FPGAs with several DSPs, various CPU SMAll systems, ddr, AD/DA, etc. Automatic routing is not possible. Fortunately, the software is not 99se (99se can not support such a complex board)

When a communication board with more than 8000 pins is manually wired for the first time, we may all feel very proud. Look at every signal layer of your cloth over and over. Although it's a bit ugly, each signal line, each fan out, and each equal length are adjusted by yourself. Look at this Layout, just like your own child. Later, we had a second child and a third child... Maybe we can't count how many children we have now.

Slowly it seems that this is a share of achievements and responsibilities, slowly began to enjoy the process of Layout. In fact, for people in Layout, the whole process is also about creation. It's like a painter painting on a canvas. Maybe other people's seEMIngly boring work will be fresh and challenging for us as long as we put our heart into it. EMC considerations, structural interference of the whole machine, channel reservation, rationality of signal wire layout, and perfection of the overall appearance... This is our art PCB manufacturers, PCB designers and PCBA manufacturers explain that for HDI engineers, Layout is the art of hardware.
