The global sales of the Galaxy S II have not only made Samsung fully complacent, but Samsung has also become a hot spot and launched multiple versions of the aircraft. Following the previous Galaxy Z (GT-i9103), a new version of the Galaxy S II today, the GT-i9100G, has also appeared on the website of the Telecommunications Equipment Certification Center of the Ministry of Industry and Information Technology. The GT-i9100G and the original version of the Galaxy S II did not change in appearance, but unfortunately, although the aircraft has appeared on the website of the Telecommunications Equipment Certification Center of the Ministry of Industry and Information Technology, the hardware configuration of the aircraft is nothing. This is relatively rare in previous models that received network access licenses.
It is widely believed that the different versions of the Samsung i9100G are based on the 1GHz dual-core Texas Instruments TI OMAP4430 processor chip. It is unclear whether the Samsung i9100G will change the material of the 4.2-inch touchscreen as the i9103 does. Super Clear LCD.
In addition, this i9100G is also equipped with Android 2.3 system and Touchwiz 4.0 interface, has 8 million pixel camera that can shoot 1080P full HD video, and built-in 1GB of RAM and 16GB of storage space, and provides such as three-axis gyroscope, accelerometer, Digital compass, GPS navigation, Bluetooth and WiFi.
SMA means surface mount assembly. It is a new generation of electronic assembly technology, which compresses traditional electronic components into a device with a volume of only a few tenths.
Surface mounting is not a new concept, it is derived from earlier processes, such as flat mounting and mixed mounting.
For the assembly of electronic circuits, a point-to-point wiring method was initially adopted, and there was no substrate at all. The packaging of the first semiconductor device uses radial pins, which are inserted into the through holes of the monolithic circuit boards that have been used for the packaging of resistors and capacitors. Active components have been widely used in the past ten years.
