In the design of high-speed DSP application system, how to transform perfect design from theory to reality depends on high quality PCB board, DSP circuit working frequency is getting higher and higher, pin more and more dense, interference increase, how t
Adjacent to these connection points, a pad or mounting hole for mounting is placed between the case ground and the circuit ground. These ground connections can be cut open with a blade to keep the circuit open, or a jump with a magnetic bead/high frequenc

In the design of PCB routing, the input and output wires should avoid crossing as far as possible, and the feedback coupling can be avoided by adding capacitance between the wires.
All kinds of reliability design in digital circuit application is related to the reliability requirements of the circuit in practical application and product engineering requirements, so it is not possible to add various kinds of high-cost "guarantee...
The basic concept of microstrip theory and the concept of microwave RF circuit and PCB design is actually an application aspect of microwave double transmission line theory.
Power part and control part separate layout, power circuit is generally large voltage, large current, high power circuit, relatively large interference. And the control circuit is low voltage, if the control part to the power part, the control part is ver
In addition, whether the need for special treatment, such as copper foil, shielding, etc., also need to be considered in the PCB design stage.
When the PCB wiring width changes, it should be carefully analyzed according to the actual situation to determine whether it will cause any impact. There are three parameters to be concerned about: how much impedance change, how much signal rise time, and
Test purpose: As PCB may be used in sea or seaside areas with high salinity in the air, its function will be affected due to poor salinity resistance, and serious accidents will be caused.
For RF-PCB wiring, each adjacent signal line (including adjacent planes) is formed to follow the basic principle of double line features (this will be explained later).
a simple and applicable method is to first lay the ground wire, then place key signals such as high speed clock signals or sensitive circuits near their ground loops, and finally route other circuits. The layout of the signal line is best arranged accordi
