Over-molding of LSM9DS1

Hi, This question is regarding the e-packaging of the LSM9DS1 sensor PCBA

Instead of packaging it in the plastic casing, We are planning to cover the PCBA with the overmolding material to cover the whole PCB including the sensor to protect it from moisture and environment.

Is overmolding advisable over the LSM9DS1 sensor given that it is a MEMS? If yes, do you suggest any specific material and process?

This has been floating for some time now, Does anyone has a view on this? It will be really helpful.

Potting or conformal coating?

Hi Clive, We are currently putting Void/Mask region over the sensor while we do a conformal coat.

This question is rather related to the Potting/Overmolding over the Sensor and its PCBA.

Coating or overmolding is OK for the sensor.

Please be aware of the maximum temperature which the sensor can withstand.
