DVIULC6-2x6 Recommendation on PCB assembly
11/17
4 Recommendation on PCB assembly
4.1 Stencil opening design
1. General recommendation on stencil opening design
a) Stencil opening dimensions: L (Length), W (Width), T (Thickness)
Figure 26. Stencil opening dimensions.
b) General Design Rule
Stencil thickness (T) = 75 ~ 125 µm
2. Reference design
a) Stencil opening thickness: 100 µm
b) Stencil opening for leads: Opening to footprint ratio is 90%.
