Conformal coating - LIS2DW12TR

[Abishek Devan]

Hi Team

We are currently working on ST PN: LIS2DW12TR in our new project. Thus, I would like to check with ST whether this part is OK to be Conformal coated? The reason is, our PCB will need to be conformal coating after all the components are populated on it. Hence would like to understand if there is any risk for this ST component to go thru this conformal coating process.

Regards,

Hi @Abishek Devan​ ,

There is in principle no issue, if the temperature of conformal coating deposition doesn't exceed the maximum absolute ratings of 125°C for long time. My suggestion is however to calibrate the part in the software after soldering + conformal coating before starting using it.

Thanks for the clarification Eleon.
