VJ 3505 ASSEMBLY GUIDELINES
1. Mounting of antennas on a printed circuit board should be done by reflow soldering. The reflow soldering profiles are shown
below.
2. In order to provide the adequate strength between the antenna and the PCB the application of a dot of heat cured epoxy glue
in the center of the footprint of the antenna prior to the antenna’s soldering to the board should be done. An example for such
glue could be Heraeus PD 860002 SA. The weight of the dot should be 5 mg to 10 mg.
