Recommended PCB Footprint – PCB Metal & Solder Mask
The PCB footprint below is only for reference.
This footprint is a Non-Solder Mask Defined layout [NSMD]. The dotted-green lines define the solder mask
apertures. The solid-red lines define the metal pad sizes.
The user should modify the design layout in order to meet their specific solder fillet requirements & solder joint
reliability requirements.
All dimensions in the figure below are in mm.

Recommended PCB Footprint – Stencil Apertures Pattern
The stencil apertures design below is only for reference.
It is based on a 6 mil [0.15 mm] stencil thickness with apertures oversized by 1 mil [0.025 mm] on the pad metal.
The user should modify the design layout in order to meet their particular solder fillet & solder joint reliability
requirements.
