Lead-Free Desktop Board

This desktop board is lead free although certain discrete components used on the board contain a small amount of lead which is necessary for component performance and/or reliability. This desktop board is referred to as “Lead-free second level interconnect.” The board substrate and the solder connections from the board to the components (second-level connections) are all lead free. Table 13 shows the various forms of the “Lead-Free 2nd Level Interconnect” mark as it appears on the board and accompanying collateral.
