Soldering conditions: Typical Soldering Profile for Lead-free Process VIII. Reminders for use of Unictron’s ceramic chip antennas: a) This chip antenna is made of ceramic materials which is relatively more rigid and brittle compared to circuit board materials. Furthermore, the length of this antenna is quite long. Bending of circuit board at the locations where chip antenna is mounted may cause the cracking of solder joints or antenna itself. b) 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. c) 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. 5F., No. 83, Kewang Rd., Longtan Dist., Taoyuan City 32556, Taiwan (R.O.C.)
