6.4 Reminders for users of Unictron’s AA099
ceramic chip antennas
6.4.1. This chip antenna is made of ceramic materials which are relatively
more rigid and brittle compared to printed circuit board materials. Bending of
circuit board at the locations where chip antenna is mounted may cause the
cracking of solder joints or antenna itself.
6.4.2. Punching/cutting of the break-off tab of PCB panel may cause severe
bending of the circuit board which may result in cracking of solder joints or
chip antenna itself. Therefore break-off tab shall be located away from the
installation site of chip antenna.
6.4.3. Be cautious when ultrasonic welding process needs to be used near
the locations where chip antennas are installed. Strong ultrasonic vibration
may cause the cracking of chip antenna solder joints.
