14. PCB Land Pattern: Si4736/37 SSOP
Figure 17 illustrates the PCB land pattern details for the Si4736/37-C40-GU SSOP. Table 20 lists the values for the
dimensions shown in the illustration.
General:
Solder Mask Design:
Stencil Design:
Card Assembly:
1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. This land pattern design is based on the IPC-7351 guidelines.
3. All metal pads are to be non-solder mask defined (NSMD). Clearance between the
4. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls
5. The stencil thickness should be 0.125 mm (5 mils).
6. The ratio of stencil aperture to land pad size should be 1:1 for all perimeter pads.
7. A No-Clean, Type-3 solder paste is recommended.
8. The recommended card reflow profile is per the JEDEC/IPC J-STD-020
solder mask and the metal pad is to be 60 µm minimum, all the way around the
pad.
