PCB Matrix LP Calculator LE 7.0

PCB Matrix LP Calculator LE is a streamlined utility for creating accurate PCB land patterns and footprints. Developed by PCB Matrix, it helps engineers, librarians, and PCB designers convert component dimensions into manufacturable pad layouts aligned with industry practices such as IPC-7351.

Key capabilities:

• Calculates pad sizes and spacing from component dimensions (lead length/width/pitch, body size)
• Supports density levels (Least, Nominal, Most) to meet different assembly goals
• Generates footprint elements including pads, solder mask and paste openings, silkscreen, assembly outlines, and courtyards
• Works in metric and imperial units
• Offers templates for common SMD packages (e.g., resistors, capacitors, SOIC, QFP/QFN, BGA)

LE edition highlights:

• Access to the core calculation engine and common package templates
• Reduced customization and export options compared to the full version
• Well-suited for learning, quick one-off footprints, and validating vendor-recommended patterns

Benefits:

• Improves footprint consistency and manufacturability
• Reduces library creation time and the risk of rework
• Bridges the gap between datasheets and PCB CAD libraries

For advanced automation, batch processing, and expanded export capabilities, consider upgrading to the full LP Calculator or related tools from PCB Matrix.
