Description
Technical field
The utility model relates to a kind of semi-conductor discrete device manufacturing technology field, specifically refers to the small-power paster lead frame part of small-power integrated circuit fields application.
Background technology
Along with scientific and technical fast development, semi-conductor discrete device product is widely used in cell phone type consumer electronics, computer and peripheral hardware, network service, a plurality of fields such as Electronic Special Equipment and instrument and meter, automotive electronics, LED display and electrical lighting; Certainly, semi-conductor discrete device profile and performance requirement in different field application are also different, take lead frame of triode as example, in the lead frame of triode of the product such as network service, instrument and meter, LED display, mobile phone application, require that profile is relatively little, thinner thickness; Simultaneously, because the base material thickness of this type of lead frame is thin, size is little, when being applied to such as automotive electronics, chemical industry, the contour vibration of food, high temperature difference and moist bad border, easily because the bond strength of plastic packaging material and lead frame occurs not, plastic packaging material is heaved at lead frame matrix surface, the phenomenon of layering, the coplanarity of its product, firmness and moisture resistant seal decline greatly, have a strong impact on useful life and the job stability of triode product.
Utility model content
The technical problems to be solved in the utility model is, after a kind of encapsulation is provided, plastic packaging material is combined firmly with lead frame cell cube, the small-power paster lead frame part that lead frame part coplanarity is good and simple in structure, small and exquisite, is applicable to the electronic devices and components field that the products such as network service, instrument and meter, LED display, mobile phone are applied.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of small-power paster lead frame part, comprise that the sideband on upper and lower both sides and several are the lead frame cell cube that matrix is arranged, between every line lead frame unit body, be provided with the company's muscle connecting for laterally, described lead frame cell cube comprises Chip Area, a positive pin, two the first side pins and two the second side pins; Described the first side pin is positioned at the same side of Chip Area, positive pin is positioned at the centre of the first side pin and is connected with middle part, Chip Area, the second side pin is positioned at the opposite side of Chip Area and symmetrical with the first side pin, and middle part, two ends, left and right, described Chip Area is provided with connection bump bar.
Compared with prior art, the utility model has the advantage of: the utility model small-power paster lead frame part, in each lead frame cell cube, there are five pins, during use, can select arbitrarily as required three pins for connecing lead-in wire, two other pin is for fixing Chip Area, this structural strengthening the stationarity of Chip Area, increased the coplanarity of lead frame part; Middle part, two ends, left and right, Chip Area is provided with connection bump bar, increased the bonded area between plastic packaging material and lead frame cell cube, greatly increased the adhesion of plastic packaging material and lead frame cell cube, can effectively prevent that plastic packaging material from producing slippage with respect to Chip Area, pin, prevent that plastic packaging material from heaving layering at front or the reverse side of Chip Area, the anti-mechanical shock of finished product and heat-resistant anti-fatigue intensity are obviously improved; This product structure is simple, small and exquisite, is widely used in the electronic devices and components field of the product application such as network service, instrument and meter, LED display, mobile phone.
Described lead frame cell cube length is 4～5 millimeters, and wide is 2～3 millimeters; This product structure is simple, small and exquisite.
Between every two row lead frame cell cubes, by longitudinal bond strip, be connected; This structure facilitates cutting.
