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

7:
b) General design rule
Stencil thickness (T) = 75 ~ 125 µm
Aspect Ratio = ^W-T---- ≥ 1.5
Aspect Area = _2----T---L-(---L-^×----+-W----W------₎ ≥ 0.66
2. Recommended stencil window
a) Stencil opening thickness: 80 µm
b) Other dimensions: see Figure 14
