Three key points for drawing high-quality PCB

PCB design is based on circuit schematic diagram to achieve the purpose and function required by circuit designers. Drawing design requires engineers to accumulate years of experience. If you want to draw high-quality circuit boards, you need to pay attention to the following aspects:

1: Overlap technology of pads. Overlap of pads indicates the overlap of holes. During drilling, the drill bit will be broken due to multiple drilling at the same location, thus damaging the holes. Which circuit board manufacturer has better products, you must check the overlap of holes layer by layer.

2: The pad technology of surface mount equipment is used for continuity testing. For very dense surface mount equipment, the distance between its two feet is very small, and its pads are also very thin. When installing test pins, they must be staggered up and down to ensure the high quality of PCB. For circuit board manufacturers who have passed the quality certification, their pads of surface mount equipment are not too short.

3: In general, circuit board factories with good reputation and good service will design the electrical grounding as a power supply in the form of flower pads. The ground plane is opposite to the image on the actual printed circuit board, and all connections are isolation wires. By the way, when drawing multiple groups of power lines or grounding isolation lines, do not leave a gap, otherwise the two groups of power supply will be short circuited, which is impossible to cause, and the connection area will be blocked.

Because PCB is a very important assembly configuration of electronic products, excellent circuit board companies have strict requirements on the quality of the circuit board factories they use. It is recommended that consumers first choose PCB from circuit board manufacturers that have passed the quality certification when purchasing circuit boards. They can ensure that they can purchase circuit boards that meet both national requirements and their own, and are eager to obtain high-quality PCB products.
