With the popularity of SMT lead-free process technology, the demand for PCB substrate is getting higher and higher. The performance of PCB can be improved from the design of PCB.
In concept, wireless transmitter and receiver can be divided into two parts: fundamental frequency and radio frequency. Includes the frequency scale of the input signal of the transmitter and the frequency scale of the output signal of the receiver.
The first step to enter the PCB circuit board system is to set the PCB preset background, including setting the grid volume and type, cursor type, version layer reference, wiring reference, etc.
For you to introduce the circuit board design precautions and operation skills :1, the processing level definition to be clear, 2, the distance from the copper foil frame can not be too close, 3, can not use the filler block picture welding pad, 4, electr
PCB design is based on the circuit schematic diagram to achieve the function required by the circuit designer. Excellent design can save production cost, achieve good circuit performance and heat dissipation performance.
With the 3D capabilities of the layout tool, designers can interactively handle their component placement in real time and correct all clearance errors in the design's mechanical features.
The following introduces common circuit board analysis methods: 1, AC equivalent circuit analysis method, 2, frequency characteristics analysis method, 3, DC equivalent circuit analysis method, 4, time constant analysis
China's pcb circuit board design and manufacturing industry is a highly competitive "field of cultivation"
From the current situation, only our country has recovered the supply of products in a short time, accelerating the trend of domestic replacement of PCB industry.
Signal integrity circuit board design criteria include SI problems, pre-design preparation, cascade, crosstalk and impedance control, high-speed nodes, technology selection, pre-wiring stage, post-wiring SI simulation, post-manufacturing stage, model sele
PCB technology is very complex, involving many aspects of the problem, whether in the design stage or the production stage, there are a lot of problems need to be answered.
Understand PCB design, PCB assembly and PCB layout in PCB related industries, and Interconnect for impedance circuit board design
The PCB processing factory explains the PCB material properties, PCB substrate, conductor and component material properties that should be considered when designing the circuit board.
