   The Min/Max Calculation section was originally inspired by IPC-7351 and subsequently by the superseding IPC-7352 – Generic Guideline for Land Pattern Design. The solder joint goals were derived from the IPC J-STD-001G - Requirements for Soldered Electrical and Electronic Assemblies. For more details, see Appendix I.
