LED switching power supply PCB board design seven stepsIn the design of switching power supply, if the PCB board is not properly designed, it will radiate too much electromagnetic interference. The PCB board design with stable power supply is now summariz
Impedance Controlled PCB Design1 IntroductionWith the development of science and technology, especially in the progress of integrated circuit materials, the calculation speed has been significantly improved, and the integrated circuit has been promoted to
Gold finger design and processing of PCBThis article comes from Jeddahshare1. The definition of gold finger (Gold Finger or Edge Connector) Insert one end of the PCB board into the connector card slot, use the pins of the connector as the outlet for the
Rigid Flex PCB Design1. PCB compositionPCB contains two important components: Core and PP (Prepreg, semi-solid sheet).Both surfaces of Core are covered with copper foil, which is used as a conductive layer, and the solid material is filled between the two
High speed PCB design is a very complex system engineering, only with the help of those who can not only calculate the physical and electrical characteristics of each component used in the design of the impact and interaction, but also must be able to aut
Generally, the parameters of PCB board layer, the distance between signal lines, the electrical characteristics of the driver end and the receiver end, and the terminating mode of signal lines all have certain influence on the crosstalk.
The second step to complete the PCB production. The first step of making a PCB, determining the physical size of the board frame, the size of the wiring and the various board layers required, can be completed through the wizard.
The exchange of PCB design/manufacturing data is the key to the information integration of electronic design and manufacturing. Therefore, it is urgent to establish a new format standard of PCB data exchange.
For small power digital integrated circuit, choose 0.2-0.5mm line width. In the same PCB, the ground and power cables should be wider than the signal cables.
Therefore, the interference source and propagation path of electromagnetic interference must be analyzed. Common electromagnetic interference in PCB design includes conduction interference, crosstalk interference and radiation interference.
Once the design data is transmitted to the PCB workshop in the form of ASCⅡ, the processor can smoothly implement process operations such as etching compensation, panel imaging, output drilling, wiring and photography.
PCB design/fabrication data was generated by electronic designers using EDA tools, including fabrication of PCBS such as light painting, assembly and test. PCB data format standard is a descriptive language to standardize PCB layout design, which is used
