Patent ID: 8250746

Claim:
A method for making an electronic device having a metallic housing, at least one bonding film and at least one metallic element, wherein the at least one metallic element is fixed to an inner surface of the metallic housing via the bonding film, comprising: providing a hot press machine having a press head; placing the at least one bonding film on the inner surface of the metallic housing; heating the press head to a first predetermined temperature of about 40° C. to about 50° C.; after the first predetermined temperature is reached, driving the press head to press the at least one bonding film to the metallic housing for a first predetermined time, thereby attaching the at least one bonding film on the metallic housing; placing the at least one metallic element on the at least one bonding film of the metallic housing; heating the press head to a second predetermined temperature of about 160° C. to about 170° C.; after the second predetermined temperature is reached, driving the press head to press the at least one metallic element to the metallic housing for second predetermined time, thereby attaching the at least one metallic element on the bonding film.
