First question asked Welcome!

Hello,

I want to use a IM72D128 device in a product that will have IP56 rating. The datasheet for IM72D128 says that it has a rating of IP57 at a device level, but how does that work when the component is mounted? Is there any requirements on the solder used, or the substrate that the component is mounted on?

 

Kind regards,

Markus Grawé

Hi @MarkusG,

Yes, you are right. IM72D128 has IP57 rating. The recommended Reflow soldering and board assembly of the microphone is given in section 7 (page: 14-15) of the datasheet.

Please also refer to the application note: MEMS microphone mechanical & acoustical implementation

Thanks and regards,

George
