Is it OK to wash pressure transducers?

[jacobq]

Our PCB assembler needs to know whether or not the following pressure transducers can be washed (e.g. to remove residue after soldering), but I could not find this information in NXP's datasheets. Could someone from NXP please provide this information? (If you need more information about the particular washing process let me know, but I am hoping that it does not make a significant difference. Assume something typical & RoHS compliant.)

Hi Jacob,

Care should be taken to prevent any cleaner from entering the port. The port side of the device is coated with a protective gel coating. The gel coating protects the active surface of the die and if the gel gets wet, device reliability can be compromised. Also, the characteristics of the gel change when wet and the device may not perform as specified. The port/hole should be covered during the wash process.

Best regards,

Tomas
