The document outlines critical considerations for high-density chip design, specifically focusing on high-pin count components. Key points include: verifying pin numbering and markings (including 510 pin tick marks), examining pin shape (square pins), ensuring adequate hole sizes and footprint accuracy (cross-referencing with datasheets, verifying top vs. bottom view footprints), inspecting edge connector design (interleaved zig-zag fingers), managing digital ground planes and high-speed signal routing, minimizing signal stubs, adhering to impedance matching for transmission lines, shortening crystal connections, utilizing guard rings around crystals, employing filters at AD pins, strategically placing drivers and receivers near connectors, mitigating EMI/RFI, avoiding trace placement under sensitive/noisy components, minimizing vias under resistors, utilizing appropriate via spacing for RF transmission lines (120 lambda rule), considering shielding cans for sensitive circuitry, utilizing close-coupled bypass capacitors near power pins, and employing low-inductance mounting techniques. |
