mechanical strength of the components will decrease
because a sudden temperature change causes
deformation inside the components. In order to prevent
mechanical damage in the components, preheating
should be required for both of the components and the
PCB board.
Preheating conditions are shown in table 2. It is required
to keep temperature differential between the solder and
the components surface ( T) as small as possible.
temperature can result in leaching of the outer electrodes,
causing poor adhesion or a reduction in capacitance
value due to loss of contact between electrodes and end
termination.

( T) between the component and solvent within the range
shown in the table 2.

excessive, the risk of cracking is higher during board
bending or any other stressful condition.
