Automated Assembly
For high-volume assembly, most users will want to auto-place the modules.
The modules have been designed to maintain compatibility with reflow pro-
cessing techniques; however, due to their hybrid nature, certain aspects of
the assembly process are far more critical than for other component types.
Following are brief discussions of the three primary areas where caution
must be observed.
Reflow Temperature Profile
The single most critical stage in the automated assembly process is the
reflow stage. The reflow profile below should not be exceeded, since
excessive temperatures or transport times during reflow will irreparably
damage the modules. Assembly personnel will need to pay careful
attention to the oven’s profile to ensure that it meets the requirements
necessary to successfully reflow all components while still remaining within
the limits mandated by the modules. Figure 31 shows the
recommended reflow oven profile for the modules.

Shock During Reflow Transport
Since some internal module components may reflow along with the
components placed on the board being assembled, it is imperative that
the modules not be subjected to shock or vibration during the time solder
is liquid. Should a shock be applied, some internal components could be
lifted from their pads, causing the module to not function properly.
