PCB DESIGN GUIDELINES FOR CHIP SCALE PACKAGE
The lands on the 20-lead LFCSP (CP-20) are rectangular. The
printed circuit board (PCB) pad for these should be 0.1 mm
longer than the package land length and 0.05 mm wider than
the package land width. The land should be centered on the
pad. This ensures that the solder joint size is maximized. The
bottom of the LFCSP has a central thermal pad.
The thermal pad on the PCB should be at least as large as this
exposed pad. On the PCB, there should be a clearance of at least
0.25 mm between the thermal pad and the inner edges of the
pad pattern. This ensures that shorting is avoided.
Thermal vias may be used on the PCB thermal pad to improve
thermal performance of the package. If vias are used, they should
be incorporated in the thermal pad at 1.2 mm pitch grid. The
via diameter should be between 0.3 mm and 0.33 mm, and the
via barrel should be plated with 1 oz. copper to plug the via.
The user should connect the PCB thermal pad to AGND.
