(released 05/2023)
Footprint Expert’s automatic padstack calculations are fundamentally based on IPC-735x formulas and geometry rules. This is the core standard Footprint Expert uses. It defines:
  • Land Pattern Naming Conventions for Surface Mount and Through-hole
  • Mathematical Model formula for pad stack dimensions
  • 3-Tier Density levels for Least, Nominal and Most
  • Courtyard Excess toe, heel, and side goals
  • IPC-compliant footprint generation rules
