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,

 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:

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.

Mounting  Pads  (2,  3,  4)

:  solder  the  antenna  mounting  pads  to  the 

soldering pads on the PCB. These pads must NOT be grounded.

 

Feed Pad (1)

: the black circle on the top of the antenna indicates the position of the feed pad 

in the bottom. Align the feed point with the feeding line on the PCB. See Figure 1.
