## **1. Introduction** 

The SGGP.25.2.A.02 is an embedded SMD ceramic GPS/GLONASS/GALILEO passive patch antenna with a low profile of 2mm thickness. It is designed for applications such as 

- navigation 

- infotainment 

- vehicle tracking/fleet management systems 

- UAV 

- telematics devices 

where a high performance solution is needed in a low profile form factor 

The antenna has been tuned to mount centrally a 50*50 mm ground plane, working at 1575.42MHz and 1602MHz, with a 3.34 dBi gain and 3.32 dBi gain, respectively. 70% efficiency is best in class. The ceramic patch is mounted via reflow process from a pick and place machine. The antenna itself is manufactured and tested in a TS16949 first tier automotive approved facility. 

For further optimization to customer specific device environments where ground-plane size or mounting location is different, which can lead to detuning, a custom tuned patch antennas can be supplied, subject to NRE and MOQ. For more details please contact your regional Taoglas facility.

## **8. Recommended Reflow Soldering Profile** 

SGGP.12 can be assembled following Pb-free assembly. According to the Standard IPC/JEDEC J-STD-020C, the temperature profile suggested is as follows: 

|||**Pb-Free Assembly**|
|---|---|---|
|**Phase**|**Profile Features**|**(SnAgCu)**|
|PREHEAT|Temperature Min(Tsmin)|150°C|
||Temperature Max(Tsmax)|200°C|
||Time(ts) from (Tsmin to Tsmax)|60-120 seconds|
|RAMP-UP|Avg. Ramp-up Rate (Tsmax to TP)|3°C/second(max)|
|REFLOW|Temperature(TL)|217°C|
||Total Time above TL (tL)|30-100 seconds|
|PEAK|Temperature(TP)|260°C|
||Time(tp)|2-5 seconds|
|RAMP-DOWN|Rate|3°C/second(max)|
|Time from 25°C to Peak Temperature|Time from 25°C to Peak Temperature|8 minutes max.|
|Composition of solder paste||96.5Sn/3Ag/0.5Cu|
|Solder Paste Model||SHENMAO PF606-P26|



Soldering Iron condition: Soldering iron temperature 270°C±10°C. 

Apply preheating at 120°C for 2-3 minutes. Finish soldering for each terminal within 3 seconds, if soldering iron temperature over 270°C±10°C for 3 seconds, it may cause component surface peeling or damage.
