Description
Technical field
The invention relates to the packaging technology of double-interface card, particularly relate to a kind of method for packing and take-up clip thereof of double-interface card.
Background technology
At present, along with the development of science and technology, smart card has been applied in every field, and smart card mainly comprises contact intelligent card, contact type intelligent card and double-interface card.Double-interface card refers to the smart card simultaneously possessing contact intelligent card and contact type intelligent card two kinds of functions; Double-interface card is with the feature of its complete function, and the green grass or young crops being more and more subject to people narrows.
The encapsulation of double-interface card is connected with intelligent card chip by the antenna on card base, to form double-interface card finished product.The packaging technology of existing double-interface card mainly contains following three kinds:
The first is the method for packing that two interface module and card base antenna directly adopt soldering.The method is milling water jacket on card base first, to spill antenna the end of a thread of double-interface card; Then, by manually adopting knife to be chosen by the two interfaces antenna spilt, and with the antenna pull-up that tweezers will be provoked; The card base of pull-up antenna mills out inner layer groove, carries out empty avoiding for later stage package module and prepare; By butt-joint or laser tin presetting on module soldering pads point fusing formed with the antenna of pull-up and weld; Whole line spot welding, put into groove by module and tentatively fix; Carry out hot weld encapsulation and electric performance test afterwards, form final products.The method is the most rational double-interface card packaging technology, and only have two pads during encapsulation, the reliable product quality after encapsulation, and the cost of raw material is minimum, process flow is the shortest.But, can not robotization in take-up process links, during take-up, rejection rate is high, and often occur choosing not initial line, choose the phenomenon of broken string, production efficiency is lower; A skilled operative employee is no more than at most 200 cards for one hour.
To be two interface module with card base antenna adopt the second that tin sheet transfers that the mode of welding encapsulates.First the method implants (pre-buried) two tin sheets while antenna implanted by double-interface card base, and two tin sheets carry out welding with two interfaces antenna the double-interface card base being formed and improve; Card base directly mills out the slot of expectation, in the middle of interior water jacket, mills out two pre-buried tin sheets of double-interface card base; Two tin sheets weld a copper cash respectively, to replace artificial take-up in first method and two of pull-up antennas; By butt-joint or laser tin presetting on module soldering pads point fusing formed with two copper cash (replacement antenna) and weld; Step afterwards and first method are substantially identical.This method solve the problem that in first method, take-up operation easily breaks, rejection rate is high.But the method increases to six means of spot welds by original two means of spot welds, improve difficulty and the weld interval of welding antenna, there is the increased risk of rosin joint and hidden danger of quality in product; Increase the cost of raw material of two tin sheets simultaneously in producing and implant the artificial of tin sheet and equipment cost.
The third is that two interface module encapsulates with the mode that card base antenna adopts conducting resinl to be connected.The method adopts high molecular conductive material that module is formed with antenna to be connected; Although its production efficiency is high, equipment realizes simple, there will be in the later stage uses because of the conductive characteristic decay of conducting resinl own, cause product life cycle short, the problem that product quality requires cannot be met; Moreover because conducting resinl is just with solder joint contact, very not firm connection, if card bends, conducting resinl will be caused to follow solder joint loose contact, and in addition, along with the increase of card service time, the aging rear contact effect of conducting resinl will be poorer.
By the comparison to above-mentioned three kinds of method for packing, two interface module and card base antenna directly adopt the method for packing of soldering to remain the most rational double-interface card packaging technology by the first, and it has reliable product quality, packaging cost is low, process flow is short advantage; But take-up operation is its important step in the method, the effect of take-up directly has influence on the production of subsequent handling, at present, easily breaks in take-up process, problem that rejection rate is high annoyings domestic and international producer always.Learn by analyzing, when take-up because antenna is embedded in card base, there is between antenna and card base larger attachment force (or bonding force), operator is when with knife or tweezers take-up, directly antenna is extracted, because antenna is comparatively thin and attachment force is comparatively large, therefore, very easily antenna is dragged disconnected.
