Dimension
1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. Dimensioning and Tolerancing per ASME Y14.5M-1994.
3. This Land Pattern Design is based on IPC-7351 pattern SOIC127P600X175-17N.
1. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder
1. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used
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 pads.
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
