Breakdown
Still in progress...
The tablet consists of a main PCB, two auxiliary PCBs, and the display sandwich.
Height
The tablet thickness is roughly 12.8mm in the middle. The height stackup is:
| Cover Glass: 1.9mm | |
| Air Gap: 0.8mm | |
| Display: 3.7mm | |
| Swell gap: 0.4mm | Main PCB: 4.8mm |
| Battery: 4.7mm | |
| Back cover: 1.3mm | |
The touchscreen is a multitouch projected capacitance screen, built with two layers of ITO on the same glass, with a insulating material between the two layers when they cross (known as single glass). The insulating material can be seen as a grid of dots when held at the right angle in sunlight.
The air gap is created by a rim of black foam, 0.8mm in height, placed right outside the active area of the display (mostly on the bezel).
The back cover has a cheap cast metal heat spreader, bonded to the outer plastic shell.
Weight
The tablet weight is roughly 580 grams. This breaks down as:
| Cover Glass/Bezel: | 147g |
| Display: | 179g |
| Main PCB: | 45g |
| Battery: | 116g |
| Back cover and side PCBs: | 94g |
| Total: | 581g |
