Can the gel sealed pressure sensors survive board wash?

[jpmorash]

Can the gel sealed pressure sensors (BMP585 or BMP384) go through a standard board wash procedure?

Thank you

Hi jpmorash,

We do not recommend cleaning without protection on the opening, as chemicals can enter the opening and affect the performance of the sensor.

(1) What is the recommended method of covering the opening?

(2) Are the gel sealed sensors MORE resistant? That is, are they more likely to survive board wash (if covered) than the other sensors in the portfolio?

Hi jpmorash,

The part of the board that is not cleaned during the normal SMT process, unless it is prone to PCB contamination during the SMT process.
We recommend maintaining cleanliness during the SMT process. But if it is indeed necessary to clean the PCB, film protection needs to be applied at the sensor opening.
