sales@unictron.com . 6.4 reminders for users of unictrons aa055a 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/cutti ng 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. introduction electrical characteristics radiation pattern layout tuning packing notes datasheet: aa055a -
