You ipc-7531a adjust three of these ranges. Solder fillet refers to the shape of the solder joint between the component lead and the PCB pad. The PQFN Silkscreen Dimensions page displays the inferred silkscreen dimensions using the package dimensions previously defined. The maximum heel spacing is calculated by adding the tolerance on the inner distance between the heels of the opposing rows of leads to the minimum heel spacing.

Adequate fillet is required to ensure both the strength and reliability of the solder joints. Enable Use Default Values to accept the displayed values. Making things is awesome.
