Insiders believe that Apple launched the WiFi version of the iPad in China on September 17. However, due to the fact that there are fewer Internet access points for WiFi in the mainland, iPad does not reflect the advantages of mobile devices. Coupled with the mini-SIM card has begun to promote with the iPhone4 licensed sales, 3G version of iPad licensed to China has reached a more appropriate point in time.

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.
