Modern ultra-thin laptops have reached such proportions that further progress in the battle to reduce the thickness measured in fractions of a millimeter. Intel Company , in particular, has developed a list of guidelines for manufacturers who intend to produce ultrabooks with case thickness of 15 mm.
Inhe following year, the thickness of keyboard backlight module for MacBook Air and MacBook Pro will be reduced from 0.4 mm to 0.25 mm. Current technology does not allow manufacturing backlight module with thickness less than 0.4 mm, so in the future Apple will switch to the modules, made by extrusion technology.
This year, Apple will sell about 15 million laptops in the next year, the company can increase the rate by 15-20%.
