Abstract
The utility model relates to the manufacturing field of ceramic capacitors, in particular to a welding framework for manufacturing the ceramic capacitors, which comprises a plurality of framework units. Each framework unit comprises a framework unit body, two ends of each framework unit body are connected with one pin respectively, roots of the two pins are bent towards the same side and lead out a welding rib strip respectively, and the two welding rib strips form a pit type pad. Compared with the prior art, the roots of the two pins are bent towards the same side and lead out one welding rib strip respectively, the two welding rib strips form a pit type pad, and the ends of chips are contacted with the welding rib strips in welded mode when the chips are welded onto the welding rib strips. Therefore, the welding framework for manufacturing ceramic capacitors greatly improves welding reliability of the chips and guarantees stable quality of final products.
Description
Technical field
The utility model relates to the manufacturing field of ceramic capacitor, is meant a kind of lead frame that is used to make ceramic capacitor especially.
Background technology
Ceramic capacitor particularly multicore group ceramic capacitor is widely used at military project, civil area because capacity is big; Its manufacture process is to adopt a lead frame; Be provided with exit and welding rib in the lead frame; Chips welding on the welding rib, is made ceramic capacitor with Chip Packaging and after removing frame waste then.When welding chips welding on the rib, soldering reliability is very crucial.Lead frame of the prior art is welded rib and exit all at grade, and chip has only a face to be connected with the welding rib, and soldering reliability can not well be guaranteed sometimes.
The utility model content
The main purpose of the utility model is to overcome the shortcoming of prior art, and a kind of lead frame that is used to make ceramic capacitor is provided, and can improve chip and the soldering reliability that welds rib greatly.
The utility model adopts following technical scheme:
A kind of lead frame that is used to make ceramic capacitor; Comprise some frame units; Each frame unit includes a frame unit body; The two ends of this frame unit body are connected with a pin respectively, and these two pin roots are to also respectively drawing a welding rib with lateral buckling, and these two welding ribs form the pads of pit types.
The first reversed dip certain distance in the horizontal direction of said two pin roots is again to draw described welding rib with lateral buckling.
Can know by above-mentioned description the utility model; Compared with prior art; The utility model a kind of be used to make ceramic capacitor lead frame since two pin roots to lateral buckling and respectively draw a welding rib, two welding ribs form the pads of pit types, with chips welding to the welding rib the time chip termination also contact with the welding rib; Thereby improve the soldering reliability of chip greatly, guarantee that end product quality is stable.
In addition, two first reversed dip certain distances in the horizontal direction of pin root make pin and pad can keep certain spacing again to draw the welding rib with lateral buckling, not only are convenient to chips welding, also are beneficial to finished product and install.
Description of drawings
Fig. 1 is used to make the plan structure sketch map of the lead frame embodiment of ceramic capacitor for the utility model is a kind of;
Fig. 2 is used to make the side-looking structural representation of the lead frame embodiment of ceramic capacitor for the utility model is a kind of.
Embodiment
Below the utility model is done further to describe through embodiment.
See figures.1.and.2; A kind of lead frame 100 that is used to make ceramic capacitor of the utility model; Comprise some frame units 10, each frame unit 10 includes a frame unit body 11, and the two ends of frame unit body 11 are connected with a pin 21,22 respectively; Two first reversed dip certain distances in the horizontal direction of pin 21,22 roots are again to the pad 25 of drawing 23,24, two welding of welding rib rib, 23,24 formation pit types with lateral buckling.Two pin 21,22 roots part of reversed dip in the horizontal direction are rake 231,241; Two pins 21,22 are kink 232,242 to the part with lateral buckling.
See figures.1.and.2; When making ceramic capacitor; Chip is put into two of pad 25 welding ribs 23,24 because pad 25 is for pit type design, with chips welding on welding rib the time chip termination also with weld rib and contact; Thereby improve the soldering reliability of chip greatly, guarantee that end product quality is stable.
An above-mentioned embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection range.
Claims (2)
1. lead frame that is used to make ceramic capacitor; Comprise some frame units; Each frame unit includes a frame unit body; The two ends of this frame unit body are connected with a pin respectively, it is characterized in that: these two pin roots are to also respectively drawing a welding rib with lateral buckling, these two welding ribs form the pads of pit types.
2. a kind of lead frame that is used to make ceramic capacitor as claimed in claim 1 is characterized in that: the first reversed dip certain distance in the horizontal direction of said two pin roots is again to draw described welding rib with lateral buckling.
