2) Refer to the graph above for an example of a recommended profile.
3) Precautions Concerning Heating Method
Since allowing the PWB to stand at a high temperature for an extended period of time may have a detrimental effect on reliability,
it is necessary to perform soldering as quickly as possible to prevent the temperature of the PWB from rising excessively.
In addition, since areas of local temperature rise may occur when using a halogen lamp or infrared heater, avoid irradiating the
surface of the PWB directly.
