An infrared surface light source generating device includes a substrate layer and a carbon material layer formed on a surface of the substrate layer and having a sheet resistance value ranged between 0.01 and 1000&#x3a9;/&#x25a1;. The carbon material layer is able to emit far infrared rays when it is heated by an amount of external low-power energy to a temperature above 36&#xb0; C. A method of manufacturing the above infrared surface light source generating device is also disclosed. The method includes the steps of (A) providing a substrate layer and (B) forming a carbon material layer that is located on a surface of the substrate layer and has a sheet resistance value ranged between 0.01 and 1000&#x3a9;/&#x25a1;. Since the method involves only a simplified manufacturing process, the infrared surface light source generating device can be manufactured at reduced cost.

A method of manufacturing plastic metallized 3D circuit includes the steps of providing a 3D plastic main body; performing a surface pretreatment on the plastic main body; performing a metallization process on the plastic main body to deposit a thin metal film thereon; performing a photoresist coating process to form a photoresist protective layer on the thin metal film; performing an exposure and development process on the photoresist protective layer to form a patterned photoresist protective layer; performing an etching process on the exposed thin metal film to form a patterned metal circuit layer; stripping the patterned photoresist protective layer; and performing a surface treatment on the patterned metal circuit layer to form a metal protective layer. With the method, a 3D circuit pattern can be directly formed on a 3D plastic main body without providing additional circuit carrier to thereby meet the requirement for miniaturized and compact electronic devices.
