Figure 5-7 Principle of Vapor Phase Soldering
Figure 5-8 Reflow Soldering Profile
During reflow, the surface tension of the liquid solder will draw 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. However, if
the footprints of the pad are not concentrically aligned, the same effect can result in
undesirable shifts as well, hence the importance of using a standard contact pattern
which leaves sufficient room for self-positioning.
After the solder has cooled, connections should be visually inspected and remnants of
the flux removed using a vapor degreaser with an azeotrope solvent or equivalent.
