ASSEMBLY INSTRUCTIONS
Reflow Soldering
• Set the furnace temperatures for pre-heating and heating
in accordance with the reflow temperature profile as
shown in the diagram. Exercise extreme care to keep the
maximum temperature below 260 °C. The temperature
shown in the profile means the temperature at the device
surface. Since there is a temperature difference between
the component and the circuit board, it should be verified
that the temperature of the device is accurately being
measured
• Handling after reflow should be done only after the work
surface has been cooled off
Manual Soldering
• Use a soldering iron of 25 W or less. Adjust the
temperature of the soldering iron below 300 °C
• Finish soldering within 3 s
• Handle products only after the temperature has cooled
off.
