Aishou APad A816 Disassemble Comparative Review
Tablet PC in the domestic market, competition is the first configuration, followed by the price, especially in the case of configuring the same price war is inevitable, but since the configuration on the surface will appear as why does the price gap ? In fact, in order to save costs, some manufacturers will purchase from the internal components, manufacturing process and other processes on the compression, so the product point of view no difference in the basic configuration, but there are significant differences within, in actual use will be from the subtle there are differences between the two.
Now we will have two Tablet PC configurations similar to but different price for dismantling, were analyzed to see what is the difference between the two place. One love from a Tablet PC master, model A816, Samsung PV210 processor, 512M memory, 8-inch screen, the other from other manufacturers, although the basic parameters and the A816 similar, but the selected materials is to be saved. Two seemingly similar products, but open internal accounting costs, a difference of 7 80 yuan is also not surprising. Quality or consumer in the end is to choose products from the price, that is, eyes of the beholder wise see wisdom.
Aishuo is the first introduction of chip manufacturers use Samsung PV210 one, using the sub-program, is the representative of one of the 8 inch android tablet, the first upgrade to Android2.3 system.
The left is APad A816, the right is the white-8-inch Samsung PV210. Open the back cover, the two products most obvious difference is the love of Master of the A816 circuit board is green, the other is blue, it is understood to distinguish by color printed circuit level, the highest level of green printing, the quality of the blue are more general, there is a yellow version is relatively the worst, the other APad A816 uses a 6-layer, while the other is a 4-layer, the higher layers of the motherboard, the process is more demanding, will be more stable.
Blue on the map marked as WiFi module, APad A816 Samsung Electro-use the WiFi module, integrated Bluetooth capabilities, the cost is about $ 6.8, WIFI module signal that is relatively stable, another product using a common The USB WiFi module.
Finally, the gap is the battery capacity, from the figure it is clear that both the capacity and size differences, love Shuo A816 3000 mAh lithium battery, two series, the other is 2000 mAh, battery shrink the greatest impact is life time, which is the process of using the most irritating.
A816 circuit board close-up, mainly on the printed BENa (the sub) symbol between the parts arranged in neat rows, printing specifications, components and connectors selected materials, the situation does not appear to fly line.
Another product, motherboard diagram, you can see many fly lines, the design layout is also more cluttered, the possible consequences of this is easy to machine failure, repair is more difficult.
WiFi antenna module plus a close-up, the Samsung APad A816 Wifi module, without the use of android Tablet PC network, so wireless connectivity is very important. In some plates, plate appeared less frequently search WIFI signal, which causes great problems is WIFI module.
In addition, post firmware upgrade is the user needs to be considered, APad A816-board encryption IC, can support exclusive firmware upgrade. The public board is not commercially available encryption IC, can not provide the firmware in the update.
