18.0 Soldering
The LMX9838 bumps are designed to melt as part of the Sur-
face Mount Assembly (SMA) process. In order to ensure
reflow of all solder bumps and maximum solder joint reliability
while minimizing damage to the package, recommended re-
flow profiles should be used.
Table 31
,
Table 32
and
Figure 13
provide the soldering details
required to properly solder the LMX9838 to standard PCBs.
The illustration serves only as a guide and National is not li-
able if a selected profile does not work.
See IPC/JEDEC J-STD-020C, July 2004 for more informa-
tion.
