STENCIL DESIGN
* Contact International Rectifier to receive an electronic PCB Library file in your preferred format.
The Stencil apertures for the lead lands should be
approximately 80% of the area of the lead pads.
Reducing the amount of solder deposited will
minimize the occurrences of lead shorts. If too
much solder is deposited on the three power
land pads the part will float and the lead pads will
be open.

Synchronous Buck Regulator
The maximum length and width of the power land
pads stencil aperture should be equal to the solder
resist opening minus an annular 0.2mm pull back to
decrease the incidence of opens to the lead lands or
use the recommended stencil design below.
