Reflow soldering profile

The Teseo-LIV3R is a high temperature strength surface mount GNSS module supplied on

a 18-pin, 6-layer PCB. The final assembly recommended reflow profiles are indicated here

below.

Soldering phase has to be executed with care: in order to avoid undesired melting

phenomenon, particular attention has to be taken on the set up of the peak temperature.

Some suggestions for the temperature profile are reported in the following

recommendations.
