ASSEMBLY PROCESS Figure 5 shows the back and front view of the TVNextTM VHF antenna, and indicates the location of the feeding point and the mounting pads: Mounting Pads (2, 3, 4): solder the antenna mounting pads to the soldering pads on the PCB. These pads must NOT be grounded. 4 3 2 1 Feed Pad (1): align the feed point with the feeding line on the PCB. Figure 5 - Pads of the TVNext TM VHF chip antenna. As a surface mount device (SMD), this antenna is compatible with industry standard soldering processes. The basic assembly procedure for this antenna is as follows: 1. Apply a solder paste to the pads of the PCB. Place the antenna on the board. 2. Perform a reflow process according to the temperature profile detailed in Table 3, Figure 7 on page 11. 3. After soldering the antenna to the circuit board, perform a cleaning process to remove any residual flux. Fractus Antennas recommends conducting a visual inspection after the cleaning process to verify that all reflux has been removed. The drawing below shows the soldering details obtained after a correct assembly process: Antenna Antenna Solder Paste ~ 0.1* mm PCB PCB Figure 6 - Soldering Details. NOTE(*): Solder paste thickness after the assembly process will depend on the thickness of the soldering stencil mask. A stencil thickness equal to or larger than 127 microns (5 mils) is required. Last updated on November 2017 (c) 2017 FRACTUS ANTENNAS, S.L. - 10 USER MANUAL TVNextTM (FR01-B3-V-0-054) The TVNextTM VHF antenna should be assembled following either Sn-Pb or Pb-free assembly processes.
