Stencil opening design

1. General recommendation on stencil opening design

a) Stencil Opening Dimensions: L (Length), W (Width), T (Thickness).

roduc b) General Design Rule

P Stencil thickness (T) = 75 ~ 125 µm

lete Aspect Ratio = W-T---- ≥ 1.5

bso Aspect Area = 2----T---L-(---L-×---+--W---W-------) ≥ 0.66

O 2. Reference design

) - a) Stencil opening thickness: 100 µm

t(s b) Stencil opening for leads: Opening to footprint ratio is 90%.
