Manual­Assembly
1. Follow ESD precautions while handling packages.
2. Handling should be along the edges with tweezers.
3. Recommended attachment is conductive solder paste.
4. Apply solder paste using a stencil printer or dot
5. Follow solder paste and vendor’s recommendations
6. Packages have been qualified to withstand a peak tem-

dependent on PCB and component layout and should
be controlled to ensure consistent mechanical and
electrical performance.
when developing a solder reflow profile. A standard
profile will have a steady ramp up from room tempera-
ture to the pre-heat temperature to avoid damage due
to thermal shock.

Solder­Reflow­Profile
A commonly used solder reflow method is accomplished
in a belt furnace using convection heat. The suggested
reflow profile Figure 16. This profile will vary among
different solder pastes from different manufacturers and
is shown here for reference only.
