Precision PCB Fabrication, High-Frequency PCB, High-Speed PCB, Standard PCB, Multilayer PCB and PCB Assembly.
The most reliable PCB & PCBA custom service factory.
Generally speaking, PCB circuit board design is based on the circuit schematic diagram to achieve the purpose and function required by the circuit designer. Of course, such PCB circuit board design also requires the designer's years of experience accumulation, then the circuit board How does the company manufacture high-quality products? The industry believes that there are the following aspects.
1, the overlap technology of the pads of the circuit board factory
The overlap of the pads represents the overlap of the holes. During the drilling process, the drill bit will be broken due to multiple drilling in the same place, resulting in damage to the hole. Therefore, which circuit board factory has a better product, then the overlap of its holes must be inspected layer by layer.
2, circuit board factory surface mount device pad technology
Surface mount device pad technology is for continuity testing. For very dense surface mount devices, the distance between his feet is very small, and his pads are also exceptionally thin. When installing test pins At the time, the position must be staggered up and down, so as to ensure the high quality of the PCB circuit board to a higher degree, and for the circuit board factory that has passed the quality certification, his surface mount device pads will not be too short.

3, the design of the circuit board factory electrical ground
Generally speaking, a circuit board factory with a good reputation and excellent service will design its electrical ground layer as a power supply in the form of a flower pad. The ground layer is opposite to the image on the actual printed circuit board. All connections will be isolated lines. By the way, when drawing several sets of power supplies or ground isolation lines, you should be very careful not to leave gaps, otherwise it will cause two sets of power supplies to short-circuit, and of course the connected area should not be blocked.
Because the PCB circuit board is a very important electronic product assembly configuration, excellent circuit board companies have strict requirements on the quality of the circuit board factories used. Therefore, it is recommended that when consumers buy circuit boards, they must first choose the PCB circuit boards of the circuit board manufacturers that have passed the quality certification. Desire for good quality PCB circuit board products.
