Notes:
General
1.
All dimensions shown are in millimeters (mm) unless otherwise noted.
2.
Dimensioning and Tolerancing per ANSI Y14.5M-1994 specification.
3.
This Land Pattern Design is based on the IPC-7351 guidelines.
4.
Connect the center ground pad to a ground plane with no less than five vias to a ground plane that is no more than
20 mils below it. Via drill size should be no smaller than 10 mils. A longer distance to the ground plane is allowed if
more vias are used to keep the inductance from increasing.
Solder Mask Design
5.
All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder mask and the metal pad is
to be 60 m minimum, all the way around the pad.
Stencil Design
6.
A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used to assure good solder
paste release.
7.
The stencil thickness should be 0.125 mm (5 mils).
8.
The ratio of stencil aperture to land pad size should be 1:1 for all perimeter pins.
9.
A 2x2 array of 1.0 mm square openings on 1.25 mm pitch should be used for the center ground pad.
Card Assembly
10.
A No-Clean, Type-3 solder paste is recommended.
11.
The recommended card reflow profile is per the JEDEC/IPC J-STD-020C specification for Small Body Components.
