Soldering guidelines

The moisture sensitivity level of the BMP280 sensors corresponds to JEDEC Level 1, see also:

•

IPC/JEDEC J-STD-020C “Joint Industry Standard: Moisture/Reflow Sensitivity Classification for non-

hermetic Solid State Surface Mount Devices”

•

IPC/JEDEC J-STD-033A “Joint Industry Standard: Handling, Packing, Shipping and Use of Moisture/Reflow

Sensitive Surface Mount Devices”.

The sensor fulfils the lead-free soldering requirements of the above-mentioned IPC/JEDEC standard,

i.e. reflow soldering with a peak temperature up to 260°C. The minimum height of the solder after

reflow shall be at least 50µm. This is required for good mechanical decoupling between the sensor

device and the printed circuit board (PCB).
