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.
Failure to provide sufficient time and effort for the PCB layout and wiring phase of the design can lead to problems in the manufacturing phase or functional deficiencies as the design moves from the digital domain to the physical reality.
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
When PCB is assembled, do not apply any solder to the top or bottom pad. Use screws with built-in washers to achieve tight contact between the PCB and the metal case/shield or ground surface bracket.
Printed circuit boards using Bluetooth technology may experience interference, data loss, and poor signal integrity if certain precautions are not taken.
What are the features of SMT processing BGA assembly: 1, the BGA pin (welding ball) is located under the package body, 2, before mounting must confirm whether it meets the process requirements, 3, in the PCB design should be as far as possible to lay it a
In the high frequency circuit, the noise of the power supply has an obvious influence on the high frequency signal. Therefore, the first requirement is that the power supply be low noise. Clean land is just as important here as clean power.
The more the number of signal networks, the higher the density of the device, the higher the PIN density, the higher the frequency of the signal design should be adopted as far as possible.
which is equivalent to reviewing the schematic diagram, modifying the scheme for design, and si simulation at the same time. There are many types of power supply with small voltage and large current on the board.
The most important material for printed circuit boards is copper, from which most boards are made.
How to design PCB for SMT patch processing: 1. First determine the function of electronic products, performance indicators, cost and overall size of the overall goal, 2. Electrical principle and mechanical structure design, according to the structure of t
