Internal components are soldered with SN96 (melting
temperature 221°C) to prevent damage during reflow. Maximum
reflow temperature for surface mounting the MGH converter is
220°C for a maximum of 30 seconds. SN60, 62, or 63 are the
recommended types of solder.

6. Pre-tin base of converter prior to soldering.
7. If less rotation of case is desired, reduce the width of the large
case pad by 0.020 inches (0.51 mm). Pad length can be
extended 0.010 inches (0.25 mm) towards the case body and an
as-desired dimension away from the case body.

Tolerance±0.005 (0.13) for three decimal places, ±0.01 (0.3) for two
decimal places unless otherwise specified. Please refer to the numerical
dimensions for accuracy.
8. Do not exceed 220°C as measured on the body of the
converter (top or bottom).
CAUTION
9. Attach the body of the case to the board with a thermally
conductive adhesive or SN60, 62, or 63 solder. The adhesive
can be electrically conductive as well. It can be applied as an
underfill post solder or dispensed and cured prior or during
solder.
Maximum reflow temperature is 220°C for a maximum of 30 seconds.
SN60, SN62, or SN63 are the recommended types of solder. See MGH
gull-wing solder pad layout. Hand soldering should not exceed 300°C for
10 seconds per pin.
10. In the presence of vibration, to ensure reliable mechanical
attachment, the body of the case should be attached with
adhesive or solder as noted above (note 7). The leads alone do
not provide sufficient mechanical attachment.
