250 °C. (Figure 5.8)
Figure 5.7 Principle of Vapor Phase Soldering
Figure 5.8 Reflow Soldering Profile
During reflow, the surface tension of the liquid solder draws the leads of the device towards
the center of the soldering area, correcting any misalignment that may have occurred
during placement and allowing the device to set flush on the pad. If the footprints of the pad
are not concentrically aligned, the same effect can result in undesirable shifts as well.
Therefore, it is important to use a standard contact pattern which leaves sufficient room for
self-positioning.
After the solder cools, connections should be visually inspected and remnants of the flux
removed using a vapor degreaser with an azeotrope solvent or equivalent.
