Description
Technical field
The utility model relates to a kind of lead frame of chip-type solid electrolyte Ta capacitor, belongs to tantalum capacitor applied technical field.
Background technology
In tantalum capacitor manufacture process, soak tantalum core liner that tantalum fuse after graphite, silver slurry need to improve the two poles of the earth and overcome the unstable situation of bonding middle appearance, to effectively reduce the series equivalent resistance of product like this, improve the quality of tantalum electrolytic capacitor product, ensure its reliability.As shown in Figure 1, its bonding adhesive force is poor for the lead frame of traditional chip-type solid electrolytic condenser, and moisture-proof ability is poor, can not effectively reduce series equivalent resistance (ESR), and its resistance to ripple current ability is poor.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model object is to provide the lead frame of a kind of resistance to ripple current ability and the good chip-type solid electrolyte Ta capacitor of high frequency performance.
To achieve these goals, the utility model is by the following technical solutions:
A kind of lead frame of chip-type solid electrolyte Ta capacitor, comprise body, described body upper punch is pressed with anode location hole, negative electrode location hole, anode weld tabs, negative electrode weld tabs, the front end that the front end of described anode weld tabs is provided with anode liner, described negative electrode weld tabs is provided with cathode pads, and the rear end that the rear end of described anode weld tabs is provided with anode pillow, described negative electrode weld tabs is provided with negative electrode pillow.
Described body is nickel strap or copper strips body.
Compared with prior art, the beneficial effects of the utility model are:
The utility model utilizes this lead frame to manufacture the chip-type solid electrolytic condenser that bottom-side electrodes is drawn, and has realized low series equivalent resistance (ESR), moisture-proof is good, reliability is high chip-type solid electrolytic condenser manufacturing technology; Use this lead frame structure, make chip-type solid electrolytic condenser fuse have better contacting with lead frame in bonding process, effectively reduce series equivalent resistance (ESR), resistance to ripple current ability strengthens.
