IR Reflow and Suggested Pad Size Layout
The VCC6 has been qualified to meet the JEDEC standard for Pb-Free assembly. The temperatures and
time intervals listed are based on the Pb-Free small body requirements and maximum parameters are
listed in Table 6, lower temperatures are also acceptable. The VCC6 is hermetically sealed so an
aqueous wash is not an issue. Frequencies >200MHz will need to be reflowed at 220C max.
