Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As Figure 1-3, the handheld device of present embodiment is a mobile phone, and the handset shell injection moulding process may further comprise the steps:
At first, making one thickness is the first base layer 2 of 0.5mm polypropylene material in a molding tool 1, has a cylindrical rod piece on the mould 1, by this cylindrical rod piece, can form a columniform through hole 5 at the first base layer 2 of making; Secondly, pasting a thickness at this first base layer 2 is the antenna 3 of the stainless steel of 0.2mm, and so that the current feed department 31 of this antenna 3 is positioned at this through hole 5 in the view field of this first base layer and this second base layer contact-making surface, so that the current feed department 31 of this antenna 3 is exposed in the zone of this through hole 5, to make things convenient for this antenna 3 to be electrically connected with outside, coat simultaneously one 1.5 micron ring epoxy resins ink laies; At last, on this first base layer the second base layer 4 of injection moulding 0.3mm, and cool off.In the actual fabrication process, the method that this antenna 3 is set can also be electron beam evaporation or magnetron sputtering, and electron beam evaporation or magnetron sputtering are for existing technology and can produce the antenna that thickness only has the 1-1.8 micron.
