What are the basic requirements for printed board design?

What are the basic requirements for printed circuit board design? Take a look:

1. Correct

  This is the most basic and most important requirement for printed circuit board design, to accurately realize the connection relationship of the circuit schematic diagram and avoid "short circuit" and "open circuit" errors. This basic requirement is not easy to achieve in PCBs designed by hand and simple CAD software. Generally, products must undergo more than two rounds of design modification.

2. Reliable

  This is a higher level requirement in PCB design. A correctly connected circuit board is not necessarily reliable. For example, unreasonable board selection, improper board thickness and installation and fixing, improper layout and wiring of components, etc. may cause the PCB to fail to work reliably. From the perspective of reliability, the simpler the structure, the smaller the use surface, the fewer the number of board layers, and the higher the reliability.

3. Reasonable

  This is a deeper layer in PCB design, and it is not easy to reach. A printed board assembly, from printed board manufacturing, inspection, assembly, debugging to complete machine assembly, debugging, until use and maintenance, are all closely related to the reasonableness of the printed board. Every difficulty may lead to increased costs and extended working hours. There is no absolutely reasonable design, only the process of continuous rationalization.

4. Economy

  This is a goal that is not difficult to achieve, but not easy to achieve, but must be achieved. Say "not difficult", choose low-priced plates, keep the size as small as possible, use direct-welded wires for connection, and choose the lowest-priced processing plant, etc., and the printed board manufacturing price will drop. However, these choices may result in poor workmanship and reliability, increase manufacturing costs and maintenance costs, and the overall economy may not be reasonable, so it is said "not easy". Saying "must" is the principle of market competition. A product with advanced principles and high technology may die due to economic reasons.

The above are the basic requirements of printed circuit board design, I hope it will help you.
