 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 12. 

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:

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.
