Introductory Tutorial for Multilayer PCB DesignBefore designing a multi-layer PCB circuit board, PCB Layout engineers need to determine the circuit board structure used according to the circuit scale, circuit board size and electromagnetic compatibility (
Place pcb components at any Angle:Double-click the component and there is a parameter called Rotation. It's the Angle of rotation. Choose the Angle you want.
PCBS with multiple layers are often used in high-speed, high-performance systems, where the multiple layers are used for direct current (DC) power supplies or ground reference planes.
Reducing electromagnetic interference is an important part of PCB board design, as long as the design to think more about this side, naturally in the product test such as EMC test will be easier to pass.
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
Although the decoupling capacitor can be placed near the through-hole, it is rendered useless at high frequencies due to the lead and through-hole inductance. Such routing will increase the area of signal ring and reduce the current radiation unfavorably.
In the ground plane segmentation and signal routing, the distribution of ground plane and important signal routing should be taken into account to prevent the problems caused by the ground plane slotting.
There is a limit to how many circuits you can fit on a board. PCBS themselves have a size upper limit for manufacturing equipment and standard panel size reasons.
The high floor board uses high TG, high speed, high frequency, thick copper, thin dielectric layer and other special materials, which puts forward high requirements for the inner line fabrication and graphic size control.
Protection measures of multilayer PCB edge radiation: The three elements of EMC problems are: electromagnetic interference source, coupling path, sensitive equipment
The following operations will be carried out in the maintenance technology: 1, inspection of components, 2, welding state analysis, 3, detection of components direction, 4, tool inspection of components, 5, power-on test
