PCB design is a 'slow work leads to meticulous work' job, where everyone has their own set of solutions. Now let the engineer introduce to you what are the precautions for PCB design?
1. PCB design should have a reasonable direction
For example, input/output, AC/
DC, strong/weak signal, high/low frequency, high/low voltage, etc. Their directions should be linear (or separate) and cannot merge with each other. Its purpose is to prevent mutual interference.
2. Choosing a Good Contact Position in PCB Design
Usually, some commonality is required, such as the multiple grounding wires of the forward amplifier should converge and then be connected to the main line. In fact, due to various limitations, it is difficult to fully achieve this, but this principle should be followed as much as possible.
3. PCB design should correctly arrange capacitors
Usually only a few Line filter/Decoupling capacitor are drawn, but it is not indicated where they should be placed. In fact, these capacitors are designed for switchgear or other components that require filtering/decoupling, and they should be placed as close to these components as possible.
4. Appropriate size of buried holes and through-holes with required PCB design wire diameter requirements
The high-voltage and high-frequency lines should be slippery, without sharp corners or chamfers, and elbows should not be used at right angles; The ground should be as wide as possible, preferably using a large area of copper; The size of the pad or upper hole is too small, or the pad size does not match the drilling size correctly. The former is not suitable for manual drilling, while the latter is not suitable for CNC drilling, etc.
5. PCB design shall minimize the number of welding points and Linear density of each via
Some problems in the early stages of circuit board production are not easy to detect and often occur in the later stages, such as excessive wire holes and careless copper sinking process, which can lead to hidden dangers. Therefore, PCB design should minimize the number of upper scoring holes as much as possible.
