Inverting the PCB
When components are exposed to sudden heat, their
mechanical strength can be decreased due to the
extreme temperature changes which can cause flexing
and result in internal mechanical damage, which will
cause the parts to fail. In order to prevent mechanical
damage, preheating is required for both the components
and the PCB board. Preheating conditions are shown in
Table 1. It is required to keep the temperature differential
between the soldering and the components surface ( T)
as small as possible.

point is used. Please confirm the solderability of Tin
plating termination chips before use.
