Defects in the PCB board design process will bring huge hidden dangers to the finished product.
Copper Clad Laminate, referred to as CCL, is a common base material, usually used in the manufacture of printed circuit boards (Printed Circuit Board, referred to as PCB).
As cars become more intelligent and electrified, automakers are increasing their demand for the quantity and precision of electronic components.
24 tips to reduce noise and electromagnetic interference in PCB design,
Signal interference is the most important factor to consider in PCB layout design. Here are some basic ideas for reference.
Designers using this approach can focus on masking the microstrip length of the copper foil in order to obtain good performance for signal integrity. For systems that use dense connectors in the communication structure, the designer can use a PCB as the t
In the high-frequency circuit, the noise of the power supply has an obvious effect on the high-frequency signal. Therefore, the first requirement is that the power supply is low noise.
The significance of copper coating is to reduce the ground impedance and improve the anti-interference ability. Reduce voltage drop, improve power efficiency.
PCB board is composed of copper foil, resin, glass cloth and other materials. Each material has different physical and chemical properties. there will inevitably be residual thermal stress, which leads to deformation.
Review according to PCB checklist, including design rules, layer definition, line width, spacing, pad and hole Settings, focusing on the rationality of device layout.
The first layer in the middle is laid with multiple GND, several lines can be laid, but do not divide each layer of copper; The second layer of VCC copper in the middle has multiple power supplies laid separately. A small number of lines can be laid, but
In order to prevent deformation of many electronic products, the thickness of the board is left at 1.0mm, 0.8mm, or even 0.6mm.
