PCB Layout Recommendations
Lattice Semiconductor
for BGA Packages
pogo pin type probes are extremely small and can handle GHz range DC frequency. Zero ohm resistors are also
commonly used in first-run boards as a way to gain access to a pad or pin.
After assembly, BGA solder point quality and integrity is visually inspected with X-ray technology as part of the fab-
rication process. A special X-ray machine can look through the plastic package, substrate and silicon to directly
view the BGA solder balls, vias, traces and pads.
Figure 14-15. Example of How Defects May Appear in an X-Ray Image
The X-ray image in Figure 14-16 shows proper alignment; no voids or defects are noted. Balls, vias and traces are
visible.
