PCBA production process for Tire pressure sensor(TPMS)

[Mitchell_shen]

In our factory, PCBA will go through water clean process.

Does Tire pressure sensor(TPMS) allow this clean process?

Hi shen，

As far as I know, factory water washing requires pure water and nitrogen dehydration. Although the TPMS meets the harsh industrial environment, the sensor package does not support water washing. It is better not to weld the sensor before cleaning. See the specification for details.
