Inverting the PCB
mechanical strength of the components will decrease
because a sudden temperature change causes
deformation inside the components. In order to prevent
mechanical damage to the components, 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 solder and
the components surface ( T) as small as possible.
deteriorated when a low temperature soldering profile
where the peak solder temperature is below the melting
point of Tin is used. Please confirm the Solderability of Tin
plated termination chips before use.
be sure to maintain the temperature difference ( T)
between the component and the solvent within the range
shown in the table 1.
