Notes:
General
Solder mask design
Stencil Design
Card Assembly
1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. Dimensioning and Tolerancing is per the ANSI Y14.5M-1994 specification.
3. This Land Pattern Design is based on the IPC-7351 guidelines.
1. All metal pads are to be non-solder mask defined (NSMD). Clearance
1. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls
2. The stencil thickness should be 0.125mm (5 mils).
3. The ratio of stencil aperture to land pad size should be 1:1 for all perimeter
4. A 2 x 2 array of 0.90 mm square openings on 1.20 mm pitch should be used
1. A No-Clean, Type-3 solder paste is recommended.
2. The recommended card reflow profile is per the JEDEC/IPC J-STD-020
