Stencil opening design
1. General recommendation on stencil opening design
a) Stencil opening dimensions: L (Length), W (Width), T (Thickness).

b) General design rule
Stencil thickness (T) = 75 ~ 125 µm
Aspect Ratio

Aspect Area = _2----T---L-(---L-^×----+-W----W------₎ ≥ 0.66
2. Reference design
a) Stencil opening thickness: 100 µm
b) Stencil opening for leads: Opening to footprint ratio is 90%.
