PCB DESIGN AND LAND PATTERN LAYOUT
The recommended PCB land pattern for the ICS-40300 should be laid out to a 1:1 ratio to the solder pads on the microphone
package, as shown in Figure 14. Take care to avoid applying solder paste to the sound hole in the PCB. A suggested solder paste
stencil pattern layout is shown in Figure 15. 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.

PCB MATERIAL AND THICKNESS
The performance of the ICS-40300 is not affected by PCB thickness. The ICS-40300 can be mounted on either a rigid or flexible PCB.
A flexible PCB with the microphone can be attached directly to the device housing with an adhesive layer. This mounting method
offers a reliable seal around the sound port while providing the shortest acoustic path for good sound quality.
