How does Shenzhen PCB Factory make high-quality products
Generally speaking, PCB circuit board production is based on the circuit schematic diagram as the basis for design, which is used to realize 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, so Shenzhen How does the circuit board factory produce high-quality products? The editor of this circuit board factory believes that there are the following aspects.
1. Design of electric strata
Generally speaking, Shenzhen circuit board factory with good reputation and excellent service will design its electric ground layer as a power supply in the form of flower pads. The ground layer is opposite to the image on the actual printed board. All connections will be isolated lines. By the way, when drawing several sets of power or ground isolation lines, you should be 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.
Second, 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 Shenzhen PCB Factory will break the drill bit due to multiple drilling in the same place, resulting in damage to the hole. Therefore, which product from Shenzhen PCB Factory is better, the overlap of its holes must have been inspected layer by layer.
Three, 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 circuit board to a higher degree, and for the circuit board company that has passed the quality certification, his surface mount device pads are not too short.
As a professional PCB circuit board supplier, our company specializes in the production of high-precision double-sided/multilayer circuit boards, HDI boards, thick copper boards, blind buried vias, high-frequency circuit boards, PCB proofing and small and medium batch boards.
