Note: all antenna pads

have (feed point and
mounting pads) have
the same dimensions.

The yellow hole located on the front of the antenna provides a visual cue to mounting the
antenna. It is located above the feed point of the antenna and is included to decrease possible
manufacturing error.

5. 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:

Figure 5 – Pads of the TVNextTM 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:

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.
