BMP280 Soldering

[YongkunLiu]

Hello,

I have a PCB design waiting to be manufactured, which uses BMP280 sensor.

According to the datasheet, a vapor process during reflow soldering may damage the sensor, in this case, how can the sensor be soldered onto the PCB?

(Obviously it is impossible to do this by hand because the sensor is too small)

Thanks for any suggestion or solution.

The BMP280 features an open cavity design (i.e. there is a small hole in the top lid), which has to be protected against all kinds of liquids. Therefore if you cannot protect the sensor as suggested above during your assembly process, vapor phase soldering may damage the sensor and we cannot guarantee its proper operation anymore. Would you be able to consider reflow convection ovens with your PCB manufacturer?
