6.3 Re-flow Temperature-Time Profile
The data here is given only for guidance on solder and has to be adapted to your process and
other re-flow parameters for example the used solder paste. The paste manufacturer provides a re-
flow profile recommendation for his product.

Opposite side re-flow is prohibited due to module weight.
Devices will withstand the specified profile and will withstand up to 1 re-flows to a maximum
temperature of 260°C. The reflow soldering profile may only be applied if the BlueMod+SR resides
on the PCB side looking up. Heat above the solder eutectic point while the BlueMod+SR is
mounted facing down may damage the module permanently.
