typography of the present invention is applicable to the base material (hand set machine shell or frame) of various material, and the selectable scope of base material is relatively wider, and is not limited to above-mentioned cited range of choice.
preferably, in step (2), the mode of printing is bat printing.
preferably, in step (2), the number of times of printing is 1 ~ 4 time, more preferably 3 times.
preferably, in step (3), put glue to carry out under the pressure of 3 ~ 5kg.
preferably, in step (3), the time of putting glue is 3 ~ 6 seconds.
further, with the gross weight of conductive silver paste for benchmark, conductive silver paste mixes primarily of the component of following percentage composition: modified epoxy, 10 ~ 20%; Silver powder, 50 ~ 70%; Solvent, 10 ~ 30%; Dispersant, 0.5 ~ 2%; Defoamer, 0.5 ~ 2%; Thixotropic agent, 0.5 ~ 1%; Coupling agent, 2 ~ 5%.
more preferably, solvent is one or both in ketone, esters solvent.
again preferably, ketones solvent is one or both in cyclohexanone, your ketone of different fluorine.Esters solvent is one or both in ethylene glycol ether acetate, 1-Methoxy-2-propyl acetate.
preferably, dispersant is the silane alcohol base ammonium salt of the block interpolymers of acidic-group, and defoamer is Polyether Modified Polysiloxanes Defoaming Agent.
preferably, thixotropic agent is aerosil, and coupling agent is silane coupler.
in addition, modified epoxy can be the polyurethane-modified bisphenol A type epoxy resin of thermoplastic hydroxy.
each constituent of above-mentioned conductive silver paste is directly buied from the market by commercial sources.
compared with prior art, the present invention has the following advantages: the present invention at the surperficial bat printing conductive silver paste of base material (mobile phone shell or frame on), and also prints conductive silver paste in the back side same position of mobile phone shell or frame.In addition, the position of the printing conductive silver paste in mobile phone shell or frame of the present invention has aperture, and the aperture inwall made by the mode of a glue also prints upper conductive silver paste, is coupled together by the conductive silver paste of the front and back of mobile phone shell or frame preferably.Like this, effectively can avoid the loose contact caused because of Long-Time Service of the antenna for mobile phone inserting conductive copper pin in traditional handicraft in installing hole or the shortcoming of damage, and decrease the technique of printing-ink again around copper pin.At the tow sides printing conductive inks of mobile phone frame or plastic housing, then by the mode of some glue, double-edged electrically conductive ink being connected is method more more effective than installation PIN needle.The first, reduce operation.PIN needle need not be installed, also just without the need to printing the ink of strong adhesion on PIN, decrease printing process, saving manpower, reducing cost.The second, the ink of tow sides printed antenna and all ink of some glue are all conductive silver paste, can better be connected, ensure that electric conductivity with wiring board.Thus, the typography of antenna for mobile phone of the present invention is simpler, and the stuctures and properties of antenna is more stable, and cost is lower, and efficiency is higher, has a good application prospect.
