Figure 1: Suggested Board Layout of Soldered Pads for BGA Packages
Notes:
1. Table 2a through Table 6 on page 11 contain the recommended guidelines for board layout
soldered pad dimensions for the following Microsemi packages (including pad dimension for
prototyping socket accordingly): CS (Chip Scale BGA, 0.8 mm pitch), FG (Fine Pitch BGA, 1.00
mm pitch), BG (Plastic Ball Grid Array, 1.27 mm pitch, CG (Ceramic Column Grid Array, 1.27 mm
pitch), CG adapter socket, and QN (Quad Fine Pitch No-Lead QFN, 0.5 mm pitch).
2. For E-tec prototyping socket soldering, Microsemi recommends using non-silver type solder paste
with 6 mils thickness.
