16 / 20 page INMP621 PCB DESIGN AND LAND PATTERN LAYOUT The response of the INMP621 is not affected by the PCB hole size as long as the hole is not smaller than the sound port of the microphone (0.25 mm, or 0.010 inch, in diameter). A 0.5 mm to 1 mm (0.020 inch to 0.040 inch) diameter for the hole is recommended. Take care to align the hole in the microphone package with the hole in the PCB. The exact degree of the alignment does not affect the microphone performance as long as the holes are not partially or completely blocked. Dimensions shown in millimeters Figure 16.
