the growth rate is the passive components and PCB as the representative of the component plate. 5G substrates, such as soft boards, high-end high-speed materials and PCB, are comprehensively distributed, benefiting from the strong flexibility of 5G and th
The shortest and widest printed line permitted by the assembly process shall be used. For high frequency devices, the printed line of the power supply is equivalent to a small inductance, which will worsen the power supply noise and cause undesired coupli
Avoid running digital clock lines and high frequency analog signal lines near the power layer; otherwise, the noise from the power signal will be coupled to the sensitive analog signal.
PCB customization, BOM, material selection and other electronic industry supply chain solutions, one-stop to meet the comprehensive needs of small and medium-sized customers in the electronics industry.
Some customers have designed contour lines for Keep layer, Board layer, Top over layer and so on, and these contour lines do not coincide, which makes it difficult for PCB manufacturers to judge which contour line shall prevail.
Correct PCB pad design, if there is a small amount of skew during patch processing, can be corrected during reflow welding due to the action of surface tension of the molten solder.
The PCB of digital circuit can be composed of a wide ground wire circuit, that is, to form a ground network to use (the ground of analog circuit can not be used in this way) with a large area of copper layer as ground, in the printed board is not used to
From the point of view of function, the hole can be divided into two categories: one is used as an electrical connection between the layers; The second is used for fixing or positioning devices. In terms of technological process, through holes are general
Vertical refers to the component body perpendicular to the circuit board installation, welding, its advantage is to save space, horizontal refers to the component body parallel and close to the circuit board installation, welding, its advantage is that th
There is no through hole between the welding pads of components without external pins (such as chip resistance, capacitor, adjustable potentiometer, adjustable capacitor,
They not only play a conductive role in the design, but also play the role of heat conduction, its thermal conductivity and heat transfer area are relatively large circuit board is an indispensable part of the electronic circuit, its structure is composed
General simulation software cannot take into account some impedance discontinuity wiring conditions due to the line model or the mathematical algorithm used. In this case, only some Temninators, such as series resistors, can be reserved on the schematic d
