Embodiment
The utility model provides a kind of inductive transformer surface plug-in mounting pin Welding Structure, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The inductive transformer surface plug-in mounting pin Welding Structure that the utility model provides, as Figure 3-Figure 4, comprise the binding post 2 be positioned on inductive transformer body 1, this binding post 2 one end is connected with the lead-in wire of inductive transformer body 1 inside, and the other end stretches along inductive transformer body 1 side surface to bottom direction (direction of pad to be welded).
Further, inductive transformer body 1 adopts ceramic material to be formed by LTCC technology sintering, ceramic body inside embeds inductance element, and back panel wiring is drawn outside ceramic body 1, one deck conductive metal film is printed at the body 1 side covering internal lead-out wire of ceramic material, this metallic film has certain thickness and width, then is prepared into binding post 2 through processing.Binding post 2 is solder joint 4 one_to_one corresponding in the arrangement and pad 3 on inductive transformer body 1 surface, that is, the distance between two adjacent pins 5 is identical with corresponding solder joint 4.As shown in figures 3 to 6, before body 1 soldered circuit board, pin 5 end is inserted in jack corresponding with solder joint 4 on pad 3 in advance, then inductive transformer body 1 is placed in correspondence position on pad 3, make the root of pin 5 be attached to the surface of binding post 2 one to one.The end of pin 5 and welding of solder joint 4 is being realized through Reflow Soldering, and the welding of pin 5 root and binding post 5.
Adopt such structural design, by inductive transformer body 1 with pad 3 welding process, due to that pin 5 is relative fixing one to one with solder joint 4 in advance, with regard to not needing, the bending adjustment waiting physics mode is carried out to pin 5, thus the firm of pin 5 root and inductive transformer body 1 internal wiring can not be destroyed, also reduce welding difficulty simultaneously, be that the welding at pin 5 two ends is carried out simultaneously, be very easy to the flexibility of welding operation.
Further, composition graphs 3-Fig. 6, this binding post 2 is that the metallic film having certain thickness and a width in the printing of inductive transformer body 1 side surface forms through sintering, and this metallic film adopts the good metal material of electric conductivity to make, and the present embodiment preferably adopts Ag films.Its preparation process is that half-finished inductive transformer body 1 is implanted to implantation plate, then applies the silver with certain thickness and width in the position of the inner lead-out wire of body 1 by being coated with silver-colored machine, and is covered by lead-out wire, forms binding post 2 after silver ink firing.In welding process, at pad 3 and the binding post 2 surface printing tin cream of circuit board, pin 5 end is inserted in the jack of corresponding solder joint 4 on pad 3, inductive transformer body 1 is placed on position corresponding to pad 3 surface, through Reflow Soldering, pin 5 end and solder joint 4 and pin 5 root and binding post 2 are welded together respectively.
