Abstract

The invention discloses a preparation method of the thin-type backlight notebook computer key, which is characterized in that: including following steps: step1, one side matte PC thin film three-dimensional printing; step2, molding the one side matte PC thin film three-dimensional printing semi-finished product by using extra-high tension gas molding machine; step3, cutting for shape the semi-finished product molded by using extra-high tension gas molding machine; step5, assembling the thin type backlight notebook computer. The advantages of the invention are that: a notebook computer volume is light and thin; the keys are backlight and characters on the keys have a three-dimensional visual effect. In the structure design, a part quantity is small and an assembly process is simple. A spray paint technology can be completely replaced. Product cost is low and a production period is short.

Description

technical field [0001] The invention relates to a notebook computer, in particular to a preparation method of a thin backlight notebook computer key. Background technique [0002] At present, notebook computers of various brands in the domestic and international markets all have a common problem, that is, the notebook computer cannot be effectively operated in an environment with insufficient light. Under the trend of notebook computers pursuing lightness and thinness, how to take into account the backlighting of notebook computer buttons and thinner and thinner shapes is an important development direction for major notebook computer manufacturers. [0003] In addition, the painting process of the exterior parts of plastic products is likely to cause environmental pollution, which has been listed as an environmental protection requirement in advanced countries. Contents of the invention [0004] The object of the present invention is to overcome the defects of the prior a...
