PCB LAND PATTERN LAYOUT
The recommended PCB land pattern for the ADMP404 should
be laid out to a 1:1 ratio to the solder pads on the microphone
package, as shown in Figure 9. Care should be taken to avoid
applying solder paste to the sound hole in the PCB. A suggested

solder paste stencil pattern layout is shown in Figure 10. The
diameter of the sound hole in the PCB should be larger than the
diameter of the sound port of the microphone. A minimum
diameter of 0.5 mm is recommended.
