Consider using blind or buried vias for complex multilayer designs to reduce signal transmission losses and improve PCB density. Optimize via sizes and aspect ratios to balance electrical performance and manufacturability.
6. Component Placement: Carefully position components on the PCB to minimize signal interference, optimize signal paths, and facilitate efficient thermal management. Consider the placement of high-power components and heat-generating devices to prevent localized heating and thermal stress on the substrate.
7. Grounding and Shielding: Implement robust grounding techniques to minimize ground loops and reduce electromagnetic interference (EMI). Utilize ground planes and shielding techniques to isolate sensitive circuitry from external noise sources and enhance EMC (Electromagnetic Compatibility) performance.
8. Manufacturability and Reliability: Design the PCB layout with manufacturability and reliability in mind. Avoid sharp corners, excessive via densities, and tight component spacings that may pose challenges during fabrication and assembly. Perform design reviews and simulations to identify potential issues early in the design process and ensure the final PCB meets performance and reliability requirements.
