STENCIL DESIGN
 The stencil apertures for the lead lands should be approximately 80% of the area of the lead lands.
 The stencil lead land apertures should therefore be shortened in length by 80% and centered on the
 The land pad aperture should be striped with 0.25mm wide openings and spaces to deposit
 The maximum length and width of the land pad stencil aperture should be equal to the solder resist
Reducing the amount of solder deposited will minimize the occurrence of lead shorts. Since for
0.5mm pitch devices the leads are only 0.25mm wide, the stencil apertures should not be made
narrower; openings in stencils < 0.25mm wide are difficult to maintain repeatable solder release.

approximately 50% area of solder on the center pad. If too much solder is deposited on the center
pad the part will float and the lead lands will be open.
opening minus an annular 0.2mm pull back to decrease the incidence of shorting the center land to
