Temperature Profile
The range of temperatures we would expect for hand lead-free soldering is between 370
degsC and 450 degsC and we recommend that the soldering iron is applied to the pins for a
max of 10 seconds.
With a 0.8mm tip there is a reasonable amount of thermal resistance so it’s not unreasonable
to increase the temperature to a maximum of 450 degsC due to wear. However, ensure that
the soldering time is not increased.
Note: A reflow process was used in the manufacture of this antenna and the necessary
corrections and tuning of the antenna to optimise performance was performed. It is not
possible to further temperature reflow this product during assembly into devices.
ONLY
hand soldering is recommended with the above mentioned characteristics.
Summary
Utilising a jig ensures correct alignment of the antenna to the PCB and also minimises the
risk of mechanical stresses being applied to the antenna during the soldering process.
