Definition of the Sij reference planes

The reference planes are defined from the

footprint

of

the

recommended

characterization board shown here

The reference is the symmetrical axis of

the

package.

The

input

and

output

reference planes are located at 2.65mm

offset

(input

wise

and

output

wise

respectively) from this axis. Then, the

given Sij incorporates this land pattern.

SMD mounting procedure

The SMD leadless package has been designed for high volume surface mount PCB

assembly process. The dimensions and footprint required for the PCB (motherboard) are

given in the drawings above.

For the mounting process standard techniques involving solder paste and a suitable reflow

process can be used. For further details, see application note AN0017.
