Optimal tuning is adjusted according to PCB layout. For additional mechanical support, it is recommended to add one drop of heat curing epoxy glue.    The glue dot should not overlap with any of the soldering pads. Apply the glue dot at the center of the antenna. The glue dot area secures the chip firmly to the PCB.

Mounting of antennas on a printed circuit board should be done by reflow soldering using the profiles shown (Figures 8, 9, and 10). 2. In order to provide the adequate strength between the antenna and the PCB apply of a dot of heat cured epoxy glue in the center of the footprint of the antenna prior to soldering the antenna to the board. An example for such glue is Heraeus PD 860002 SA. The weight of the dot should be 5 mg to10 mg.
