Embodiment
Following with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is done further explain.
The circuit board combination with thick film circuit that preferred embodiment of the present invention is described comprises a circuit board and is located at the thick film circuit on this circuit board.
See also Fig. 4, thick film circuit 10 comprises a thick film matrix 11 and a plurality of pin 13.These thick film matrix 11 inside are provided with circuit, and its top is provided with user's paste card cap 12, and the bottom is provided with a plurality of pads 14 that link to each other with the I/O interface.This user's paste card cap 12 is used to make things convenient for the subscriber set paster.These a plurality of pins 13 are welded on the pad 14, and staggered this thick film matrix 11 both sides that are arranged in, therefore the just corresponding I/O interface of pin 13.Said staggered arranging is meant that when a side had pin to draw on the pad 14 of thick film matrix 11, the corresponding position of its opposite side just can be vacated in the embodiment of the invention, and the like.More than be merely the preferred embodiments of pin 13 arrangement modes, it is interlaced that the staggered rule of arranging of the pin of thick film circuit is not limited to single pin, also can be that a plurality of pins are interlaced.As shown in Figure 5, be a plurality of thick film circuits parallel second embodiment that arranges on circuit board: the pin staggered rows mode for cloth of thick film circuit is staggered in twos.And for example shown in Figure 6, be a plurality of thick film circuits parallel the 3rd embodiment that arrange on circuit board: to be that single pin is staggered, two pins of three pin alternation sums are staggered be arranged in order the pin arrangement mode of thick film circuit.It is thus clear that but the staggered rows mode for cloth of the pin of thick film circuit is very flexible vary.
See also Fig. 7,, be used for comprising a junction 20 and a plurality of pin 13 with the nead frame of thick film matrix 11 assemblings for realizing thick film circuit 10 pins 13 staggered arranging.This connecting portion 20 comprises one first cantilever 21 and one second cantilever 23, be connected through intercell connector 22 between this first cantilever 21 and second cantilever 23, and its junction is equipped with cut groove (indicating).These a plurality of pin 13 staggered being arranged on this first cantilever 21 and second cantilever 23, the one of which end is unsettled, and the other end links to each other with first cantilever 21 or second cantilever 23.For the ease of separating with this connecting portion 20 by a plurality of pins 13; The junction of this connecting portion 20 and these a plurality of pins 13 can be provided with cut groove (like the V-type groove etc.); Perhaps will these a plurality of pins 13 with this connecting portion between be arranged to be connected (a kind of syndeton of similar stamp hole), perhaps other separated structures of being convenient to well known in the prior art.。Distance between these a plurality of pins that are crisscross arranged 13 is corresponding with the pad 14 of thick film matrix 11.A unsettled end of this pin 13 is provided with two columns 130, and the spacing of this two column 130 is corresponding with the thickness of thick film matrix 11.The column 130 of the free end of these a plurality of pins 13 is arranged and is formed a draw-in groove, cooperates with thick film matrix 11.
When the thick film matrix 11 of thick film circuit 10 is assembled with nead frame; Only need thick film matrix 11 is put into draw-in groove; Make each column 130 of pad 14 and pin 13 corresponding and weld together; Then intercell connector 22, first cantilever 21 and second cantilever 23 are removed along cut groove, just can be accomplished the assembling of thick film matrix 11 and pin 13.
Please continue to consult Fig. 8, nead frame also can only comprise one first cantilever 21, and promptly first cantilever 21 and second cantilever 23 are separate structures.The pad 14 of corresponding thick film matrix 11 reserves the vacant locations of the pin 13 of staggered thick film matrix 11 opposite sides of installing with it between the pin 13 on this first cantilever 21 at this moment.During assembling, only need 21 staggered the cooperating with thick film matrix 11 of two first cantilevers just can.
The present invention also provides a kind of circuit board that uses above-mentioned thick film circuit.
In order to use thick film circuit 10 provided by the invention; Reach the purpose of effective raising thick film circuit board circuit 10 density; The present invention also provides a kind of circuit board that can be used with this thick film circuit 10, and this circuit board can be a printed circuit board (PCB), also can be the circuit board of other types.
See also Fig. 9, be the local pad sketch map of circuit board.This circuit board 20 is provided with a plurality of parallel first pad 021 and second pads 022 of arranging; This first pad 021 comprises the first row welding assembly 210 and secondary series welding assembly 211; Every row welding assembly has a plurality of pads 212, and the pad of this first row welding assembly 210 and secondary series welding assembly 211 212 is staggered arranges and corresponding with the pin 13 of thick film matrix 11 both sides of thick film circuit 10.This second pad, 022 structure is identical with this first pad 021; Also comprise the first row welding assembly 220 and secondary series welding assembly 221; The secondary series welding assembly 211 of its first row welding assembly 220 and first pad 021 is adjacent; Pad 222 on it is inserted into the vacancy of secondary series welding assembly 211 pads 212 of first pad 021 successively, forms the layout that interleave is arranged with it.
See also Figure 10, be a plurality of thick film circuits parallel first embodiment that arranges on circuit board.After the welding of thick film circuit and circuit board, thick film circuit 10 is gone up parallel arranging at circuit board (figure does not show), and adjacent thick film circuit 10,10 ' sides adjacent pin 13,13 ' interleave are arranged on the circuit board.The pin 13 of thick film circuit 10 is inserted into the vacancy between thick film circuit 10 ' the sides adjacent pin 13 ' successively, thereby the spacing between the thick film matrix 11 of thick film circuit 10 ' and thick film circuit 10 ' is dwindled, and has practiced thrift wiring space.
Can find out by preferred embodiment of the present invention; The pin of thick film circuit of the present invention adopts staggered mode of arranging; As a plurality of thick film circuits are parallel when being installed on the circuit, the pin that two thick film circuits are adjacent inserts the vacancy of the other side's pin because of interlocking and arranging and form successively, has shortened the distance between two thick film circuits; Strengthened the density of the thick film circuit on the circuit board, helped circuit board simultaneously and develop to microminiaturization.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All any modifications of within spirit of the present invention and principle, being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
