EMI control techniques

What guidelines should be adhered to in PCB stack-up design?

The laminated design of PCBs must follow two key principles: each wiring layer should have an adjacent reference layer, and the distance between power and ground layers must be minimized to enhance coupling capacitance, with various configurations detailed for different board layer counts to address electromagnetic compatibility and signal integrity issues.

What are the types of EMC interference associated with PCB duplication?

To effectively manage electromagnetic interference (EMI) and match the original PCB’s performance, a copied PCB must thoroughly understand EMI technologies and implement strategies such as filtering, shielding, and minimizing energy from radiation sources.
