Notes:
1. All dimensions are in millimeters
2. Dimensioning and tolerancing according to ASME Y14.5M-1994
3. Unless specified, dimensions are symmetrical about center lines.
4. Via hole recommendations: 0.025 mm Cu via wall plating (minimum),
soldermask on the far side should tent or plug via holes.
5. Stencil recommendations: 0.10 mm stencil thickness, laser cut
apertures, trapezoidal walls and rounded corners offer better paste release.
6. Solder mask recommendations: contact board fabricator for recommended
solder mask offset and tolerance.
