Internal components are soldered with SN96 (melting

reflow temperature for surface mounting the MGA converter is

recommended types of solder.

3. Connect "no connection" pins to case ground to reduce EMI.

4. Center pad should not have a solder mask. Solder, copper, or
Au/Ni plate are preferred over solder mask for adhesive attach.

5. Pre-tin base of converter prior to soldering.
Weight: 15 grams max.
6. 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.
Dimensions in inches (mm)
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.
7. Do not exceed 220°C as measured on the body of the
converter (top or bottom).
CAUTION
8. 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 MGA
gull-wing solder pads layout. Hand soldering should not exceed 300°C
for 10 seconds per pin.
9. 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 8). The leads alone do
not provide sufficient mechanical attachment.
