Routing Examples
Outline of Substrate
8 Bit , 3 x 3 Array
(10X)
1.27 mm pitch land
patterns are shown.
5 mil line widths shown.
Blind via to Vtt

Lines
Open via’s on top of
land pads are not
recommended due to
solder wicking.
32 Bit , 3 x 12 Array
(5X)
1.00mm Pitch (B7) = 0.51mm/.020 inch (minimum)
1.27mm pitch (B6) = 0.64mm/.025 inch (minimum)
For .006" Thick Solder Paste Stencil, Aperture Opening Should
be Equal to the PCB Pad Diameter.
