Notes:
General
1. All dimensions shown are in milllimeters (mm) unless otherwise noted.
2.
Dimensioning and Tolerancing is per the ANSI Y14.5M-1994 specification.
3.
This Land Pattern Design is based on IPC-SM-782 guidelines.
4.
All dimensions shown are at Maximum Material Condition (MMC). Least Material
Condition (LMC) is calculated based on a Fabrication Allowance of 0.05 mm.
Solder Mask Design
1. All 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
1.
A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be
used to assure good solder paste release.
2.
The stencil thickness should be 0.125 mm (5 mils).
3.
The ratio of stencil aperture to land pad size should be 1:1 for the perimeter pads.
4.
A 1.45 x 1.45 mm square aperture should be used for the center pad. This provides
approximately 70% solder paste coverage on the pad, which is optimum to assure
correct component stand-off.
Card Assembly
1. A No-Clean, Type-3 solder paste is recommended.
2.
The recommended card reflow profile is per the JEDEC/IPC J-STD-020C specification
for Small Body Components.
