Description
Technical field
The present invention relates to SMD type circuit terminal, particularly relate to SMT encapsulation circuit.
Background technology
Along with electronic product is to the development in portability, miniaturization, networking, high-performance and high density direction, Circuit assembly technology and I/O pin count are had higher requirement.Traditional thick film circuit product uses single row direct insert, dual-in-line two kinds of encapsulation technologies and traditional SMT formula encapsulated circuit, the restriction of circuit miniaturization and efficient SMT assembly technical requirement more and more can not be met owing to being subject to packaging technology, production cost and small product size, and its lead-in wire easily bends, is out of shape or fractures in complete machine assembling, quite strict to the technological requirement of assembling, the large-scale popularization and application of thick film circuit is restricted.Fig. 3-1 and Fig. 3-2 is single-row resistor network product design structural representations, and Fig. 4-1 and Fig. 4-2 is traditional SMT formula encapsulated circuit contour structures schematic diagrames, its major defect is 1, product length and exit quantity proportional, volume is large; 2, packaging density is limited; 3, single-row resistor network products application is difficult to realize automatic assembling, and production efficiency is low; Although tradition SMT formula encapsulated circuit can realize automatic assembling, its lead-out wire is soft, and coplane degree is poor; 4, thick film circuit tow sides pin is not independent.
Summary of the invention
The object of this invention is to provide a kind of two-sided independence many pins band latching circuit terminal, key property designing requirement can not only be met, make the application of thick film circuit mutually compatible with efficient SMT mounting technology simultaneously, and improve integrated level and the reliability of thick film circuit product.
The technical scheme realizing the object of the invention is: a kind of two-sided independence many pins band latching circuit terminal, it is characterized in that being connected to each other together by two circuit terminals by the hole on substrate, each circuit terminal comprises plastic feet, each plastic feet is equipped with lead terminal, each plastic feet is designed with self-locking pillar and self-locking hole, wherein each exit of lead terminal is independently.
Two edge designs of a plastic feet have self-locking pillar wherein, are designed with self-locking hole in the center of plastic feet.
There is self-locking hole in two edge designs of another one plastic feet, be designed with self-locking pillar in the center of plastic feet.
Structurally, double-edged 48 leading-out terminals of this circuit terminal are absolute construction.Go between from general thick film circuit tow sides leading-out terminal cassette interconnect, mutually independent different, time unrelated for ceramic substrate thick film circuit tow sides, the connected mode of conventional lead can not meet instructions for use.Therefore, we devise two-sided independence many pins band latching circuit terminal according to the feature of product.Each exit of circuit terminal is independently, each exit double-edged on thick film circuit independently can be drawn.And the use of circuit terminal is the mode that have employed SMT is welded on thick film circuit.Consider that two circuit terminal bases are working of plastics, length is 42mm, so long and narrow working of plastics, deformation can be produced through high temperature, the reliability of such product is just without guarantee, the coplane degree of same product is also difficult to ensure, we punch on substrate for this reason, and two circuit terminals are connected to each other together by the hole on substrate.Circuit terminal have employed Interference Fit Design, make two circuit terminals have certain pining down each other; Escape to expect mouth in the diverse location increase of working of plastics again, reduce the thermal deformation under high temperature action.
The Application and Development of two-sided independence many pins band latching circuit terminal has obtained the affirmative of user, with its double-sided circuit independent isolating, advantage simple for assembly process, in communications industry, occupied certain status, and application surface is also progressively expanding.Meanwhile, succeeding in developing of two-sided independence many pins band latching circuit terminal, the connected mode for thick film industry exit has started a new developing direction.

Embodiment
As shown in Fig. 1-1 and Fig. 1-2, plastic feet 1 is equipped with 24 lead terminals 3, two edge designs of a plastic feet 1 have self-locking pillar 4 wherein, are designed with self-locking hole 2 in the center of plastic feet; There is self-locking hole 2 in two edge designs of another one plastic feet 1, be designed with self-locking pillar 4 in the center of plastic feet 1.
Integrated circuit terminal overall dimension is that 41.5mm × 3.0mm × 1.8mm(does not comprise self-locking device size).Plastic feet is arranged 24 by the spacing of 1.27mm the hole of lead terminal has been installed, around hole, devised some escape to expect mouth, the stress be used for when discharging high temperature process; Be designed with self-locking pillar or self-locking hole at two edges of plastic feet and center, self-locking pillar and self-locking hole are used for resisting high temperatures and add the distortional stress in man-hour after installing.Circuit terminal is the terminal connecting thick film circuit and application circuit, and 24 lead terminals 3 are installed to after on plastic feet 1, compresses, make the solder side of all lead terminals 3 be in same horizontal plane through unified.
When two-sided independence many pins band latching circuit terminal uses, the two sides pad of thick film circuit all needs Printing Paste, then be placed on special Revolving disc, first the circuit terminal with 2 self-locking pillars is installed on thick film circuit, upset thick film circuit, again the circuit terminal with 1 self-locking pillar is installed on thick film circuit, the thick film circuit installing a whole set of circuit terminal is put on special compression tooling and the self-locking device of circuit terminal is compressed, finally by hot air reflux weldering, circuit terminal is welded on thick film circuit, forms final finished product.
It should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in previous embodiment, or replaces on an equal basis wherein portion of techniques feature.
Within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
