Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, with specific embodiment, the utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, the utility model triode 100 is in order to be electrically connected with external circuit, and described triode 100 includes triode chip 2 that substrate 1 is connected with described substrate 1 and is coated on the packaging body 3 outside described triode chip 2.
Substrate 1 of the present utility model is circuit board.Described substrate 1 includes the first face 16 being oppositely arranged and the second face 17 and turns on blind hole 14, described first face 16 is connected with described triode chip 2 and is provided with the first electrode 11 on the first face 16, described second face 17 is provided with the second electrode 12 in order to be connected with external circuit, and described conducting blind hole 14 is arranged between described first electrode 11 and the second electrode 12.
Conducting blind hole 14 between described first electrode 11 and the second electrode 12 is formed by radium-shine perforation, described conducting blind hole 14 is cylindrical, two or three conducting blind holes 14 it are provided with, it is of course also possible to change the quantity of conducting blind hole 14 as required between each first electrode 11 and the second electrode 12.In described conducting blind hole 14, plating forms the 3rd electrode 13, and described 3rd electrode 13 plays electric connection the first electrode 11 and effect of the second electrode 12.
Described triode chip 2 is in cuboid, and includes bottom surface 22, the length of the bottom surface 22 of described triode chip 2 and the wide length less than described substrate 1 and width.The bottom surface 22 of described triode chip 2 is connected with the first face 16 of described substrate 1, and is provided with the 4th electrode 21 on described bottom surface 22.Being coated with solder 15 on described first electrode 11, described 4th electrode 21 is fixed together so that the first electrode 11 and the 4th electrode 21 are electrically connected with by welding manner with described first electrode 11.
Described bottom surface 22 is formed with three, left, center, right in strip and the 4th electrode 21 of parallel distribution.Triode 100 of the present utility model is NPN type triode, and the right and left is N-type electrode, and centre is P-type electrode.Certainly, in other embodiments, described triode 100 can also be PNP type triode.
The quantity of described first electrode 11 is three, and in strip and parallel distribution, fourth electrode 21 one_to_one corresponding described with three is arranged.The quantity of described second electrode 12 is three, respectively base stage, collector and emitter, and described base stage is electrically connected with the first middle electrode 11, and collector and emitter is the most corresponding with the first electrode 11 of both sides to be electrically connected with.Thus, 11, three described second electrodes 12 of three described first electrodes and three described 4th electrode 21 one_to_one corresponding are arranged.
After described triode chip 2 and described substrate 1 weld together; it is injection molded with packaging body 3 by encapsulating; the length of described packaging body 3 and the wide length equal to described substrate 1 and width; the height of described packaging body 3 is higher than the height of described triode chip 2; therefore; described triode 100 can be coated on described triode chip 2 around, plays the effect of protection triode chip 2.Described packaging body 3 selects insulating materials.
The triode 100 of present embodiment, length and width only has 2.4mm, and height only has 1mm, and can reduce the most further, can meet the needs of existing major part electrical equipment.
Triode 100 of the present utility model, replaces existing conducting wire frame structure by arranging substrate 1, so that the volume-diminished of triode 100, meets the requirement that existing electrical equipment volume is the least；Replace existing triode pin by arranging the second electrode 12 in the bottom of substrate 1, will not rupture, the most perishable, extend the service life of triode 100.
Above example is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent, without deviating from the spirit and scope of technical solutions of the utility model.
