Editor’s Note: In modern high-speed designs, analyzing signal integrity, power integrity, and EMC separately is not enough; a holistic approach is essential for successful design. Background Issue: When signals cross over segmentation areas between adjacent reference planes on a layer, discussions about signal integrity often arise. Some argue that signals should not cross the segmentation […]

PCB Pad Design Guideline(2)
4.3.9 When designing multilayer boards, attention should be paid to components with metal casings that are in plug-in packages and make contact with the printed circuit board. The top layer pads must not be opened. They must be covered with green oil or silkscreen ink (such as two-pin crystals, three-pin LEDs). 4.3.10 When designing and […]
PCB Pad Design Guideline(1)
Standardize the PCB pad design process, define the relevant parameters of PCB pad design process, ensuring that the PCB design meets technical specification requirements such as manufacturability, testability, safety regulations, EMC, and EMI, and construct the advantages of process, technology, quality, and cost in product design. This specification applies to the PCB process design of […]
