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.
PCB copying board design and manufacturing is from the subtraction method to addition method, this paper mainly describes the PCB subtraction method and addition method related concepts and manufacturing process, for your reference to learn!
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
In the design of PCB board, PCB anti-ESD design can be realized by layering, proper layout and wiring and installation. In the process of circuit board design, most design modifications can be limited to adding or subtracting components through prediction
The arrival of the intelligent age, not only brings convenience to people's lives, but also has a profound impact on all industries, so the PCB copy board, design put forward higher requirements, professional PCB copy board companies should continue to im
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.
