Whatever the cleaning process is or will be, after cleaning make sure you check on X-Ray for any solder balls/debris in microphones. This is a friendly reminder to check, unless you want to receive customer complaints. Been there, seen that - we went

First check the datasheet to see if it says do not Xray. I have seen tiny microphones with a do not Xray warning.

Can you install the part post-smt with no clean flux?

Hi there! I'm an engineering student from Toronto, ON looking for someone to mount a MEMS microphone for me for a school design project. Trouble is, I need a reflow oven for the proper surface mount and my university doesn't have access to one. K

Hi, I am facing high fall out of microphone low sensitivity issues. This microphone is soldering thru SMT soldering with low peak temperature profile which peak at 232 DegC to 240 DegC and have skipped X-Ray inspection but still seeing fall out espec

Check the microphone data sheet to find out what the max temperature is...if it's not listed, call the manufacturer. Are you water-washing the board after assembly? Could be water intrusion/entrapment in the microphone. Again, check the data she

Hey folks, I have a few designs that I'm using a MEMS I2S microphone on, and the PCBs have to be cleaned as I use water based SAC305 - but the supplier states to NOT ultrasonically clean their microphones. Has anyone here been through the process of

Thanks for the suggestion. Unfortunately, there are 2 issues with adding them after: - The first is that doesn't scale to 1000's of board - The second is that half (or more) of the boards are double sided, complete PCB coverage on both sides and nee

I agree with everyone here that says microphones are meant for no clean processes. Nothing will protect the device from an inline or batch wash. The mic should have been mounted on a different board if it must be washed. The one suggestion I have is
