The metal back cover of thermal coefficient radiates, and mobile phone sense of touch temperature control is at 40 DEG C or less.Now, in order to import 5G communication and
Wireless charging technology, metal back cover can generate electromagnetic shielding effects signal quality, and each mobile phone vendor starts using glass, ceramics
And plastic or other material is as cell phone back cover.
Glass and plastics, can be outer by the dicoration of mobile phone with more the characteristic of high penetration sense in addition to not influencing signal quality
It sees to be promoted and arrives higher visual quality, therefore driven the flourishing hair of pad pasting factory, DECO membrane material factory, plated film factory and relevant device factory
Exhibition.However, the thermal conductivity coefficient (k) of glass and plastics is lower, respectively 0.75W/(mk) and 0.25W/(mk), in spite of gold
Belong to center thermal contact conductance, but heat transfer efficiency is not as good as almag category back-cover (k=54-100 W/(mk)), and the easy hair in mobile phone
Hot component and battery too tight plate-laying cause centralized heat energy, mobile phone Operating ettectiveness to reduce and have the risk of explosion.
The polychromy of cell phone back cover mostly uses greatly DECO pad pasting at present, and structure is as shown in Figure 1, but because membrane material is thicker
(0.1mm) and material are partially hard, and pad pasting yield is lower on the 3D glass of big curvature, therefore begin with brand quotient and transfer 2.5D/3D to
The direct plated film of glass, structure is as shown in Fig. 2, either pad pasting or direct plated film, the most inner side of back-cover can stick artificial stone at present
Black cooling fin (k=100-200 W/(mk)), it helps the thermal energy of processor via glass, quickly conducts heat to come.Stone
Black fin thickness about 0.03 ~ 0.1mm and material is partially hard, usually topical patch leads to mobile phone at runtime in back-cover
(1hr), rear cover maximum temperature point are 44 DEG C, and the hot and cold temperature difference of rear cap surface is 7 DEG C.It such as wants whole face patch may cause to stick up
Song leads to back-cover installation out-of-flatness, indicates that the radiating mode of this mode still needs to optimize.
