본 고안은 탄탈콘덴서에 관한 것으로, 더욱 상세하게는 콘덴서의 기판을 납조에 침적시킬 때 납조의 열에 의한 영향을 받지 않도록 하는 돌출턱을 구비한 탄탈콘덴서에 관한 것이다.The present invention relates to a tantalum capacitor, and more particularly, to a tantalum capacitor having a protruding jaw so as not to be affected by the heat of the lead bath when the substrate of the capacitor is deposited in the lead bath.
제1도는 종래의 실시예에 따른 탄탈콘덴서의 사용상태를 나타내는 도면이다.1 is a view showing a state of use of the tantalum capacitor according to a conventional embodiment.
동도면에서, 탄탈콘덴서(0)는 내부에 소자(12)를 구비하며, 전술한 소자(12)는 하측부에 양극과 음극에 연결되는 리드(20)를 구비한다.In the same figure, the tantalum capacitor (0) has an element (12) therein, and the element (12) described above has a lead (20) connected to the anode and the cathode at the lower side.
또한, 전술한 소자(12)의 외주연은 절연체 역할과 소자의 지지체 역할을 하는 에폭시수지(14)가 둘러싸고 있고, 전술한 구성을 갖는 콘덴서(10)가 기판(16)에 장착이 될 때 기판(16)에 삽입되어 하측으로 돌출되는 리드(20)는 납조에 침적시 납이 묻어 솔더부(18)가 형성됨으로서 기판(16)에 고정된다.In addition, the outer periphery of the aforementioned element 12 is surrounded by an epoxy resin 14 serving as an insulator and a supporter of the element, and when the capacitor 10 having the above-described configuration is mounted on the substrate 16, the substrate The lead 20 inserted into the protrusion 16 and protruded downward is fixed to the substrate 16 by forming a solder 18 by depositing lead when the lead bath is deposited.
그러나, 진술한 구조에서는 다음과 같은 문제점이 발생한다.However, the following problem arises in the stated structure.
기판(16)에 콘덴서(10)를 장착한 후, 납조에 침적하여 콘덴서(10)의 리드(20)를 납땜하는데, 전술한 납조의 온도는 220℃ - 240℃의 고온으로 전술한 납조에의 침적시 고온이 리드 등을 통해 콘덴서(10)의 내부에 직접 전달되지만, 탄탈 콘덴서(10)는 절연체 역할을 하는 애폭시수지(14)가 둘러싸고 있어 열의 방출이 용이하지 않으므로 콘덴서(10)의 오픈(open)불량이 발생하여 콘덴서의 신뢰성이 저하되는 문제점이 있다.After attaching the condenser 10 to the substrate 16, the lead 20 of the condenser 10 is soldered by immersing it in a lead bath. The temperature of the above-described lead bath is at a high temperature of 220 ° C-240 ° C. While the high temperature is directly transferred to the inside of the capacitor 10 through the lead during deposition, the tantalum capacitor 10 is surrounded by the epoxy resin 14, which serves as an insulator, is not easy to release heat, so the opening of the capacitor 10 There is a problem in that an open defect occurs and the reliability of the capacitor is lowered.
따라서 본 고안은 전술한 문제점을 해결하기 위해 안출된 것으로, 기판에의 콘덴서의 장착시 납조로부터 전해지는 열에 의한 영향을 받지 않는 돌출턱을 구비한 탄탈콘덴서를 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a tantalum capacitor having a protruding jaw that is not affected by heat transmitted from a solder bath when the capacitor is mounted on a substrate.
상기 목적을 달성하기 위한 본 고안은 내부에 소자를 구비하고, 하면부에 리드를 형성한 탄탈콘덴서에 있어서, 상기 탄탈콘덴서의 기판과의 접촉 부위인 콘덴서의 하면부에 돌출턱을 형성하여 구성됨을 특징으로 한다.The present invention for achieving the above object is provided in the tantalum capacitor having a device therein, and the lead is formed in the lower surface, it is configured by forming a protruding jaw in the lower surface of the capacitor which is a contact portion of the tantalum capacitor. It features.
이하에서는 첨부한 도면을 참조하여 본 고안의 양호한 일실시예에 따른 돌출턱을 구비하는 탄탈콘덴서를 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described a tantalum capacitor having a protruding jaw according to a preferred embodiment of the present invention.
제2도는 본 고안의 양호한 일실시예에 따른 돌출턱을 구비한 탄탈콘덴서의 사용상태를 도시하는 도면으로서, 내부에 소자를 구비하고, 하면부에 양극리드(20)을 구비한 콘덴서(22)는 기판(16)과 접하는 콘덴서(22)의 하면부에 돌출턱(24)을 형성하여 구성되어 있음을 알 수 있다.2 is a view showing a state of use of a tantalum capacitor having a protruding jaw according to a preferred embodiment of the present invention, which includes an element inside and a cathode 22 having an anode lead 20 at a lower surface thereof. It can be seen that the projecting jaw 24 is formed at the lower surface portion of the capacitor 22 in contact with the substrate 16.
전술한 돌출턱(24)은 1-2mm의 길이로 형성하는 것이 바람직하며, 양극리드(20)의 중간부위에 위치한다.The above-described protruding jaw 24 is preferably formed to have a length of 1-2 mm, and is located in the middle of the anode lead 20.
전술한 구성을 갖는 본 고안에 따른 탄탈 콘덴서(22)는 기판(16)에 장착시 제2도에 도시되어 있는바와 같이 돌출턱(24)이 기판(16)에 접할수 있도록 장착을 하며, 기판(16)에 장착된 콘덴서(22)는 기판(16)의 하측부에 돌출한 리드(20)를 납조에 침적하여 솔더부(ㅂ18)를 형성함으로 기판(16)에 콘덴서(22)의 장착을 실시한다.Tantalum capacitor 22 according to the present invention having the above-described configuration is mounted so that the projection jaw 24 is in contact with the substrate 16 as shown in FIG. The capacitor 22 mounted on the substrate 16 deposits the lead portion 20 protruding from the lower portion of the substrate 16 in a solder bath to form a solder portion 18 to thereby mount the capacitor 22 on the substrate 16. Conduct.
납조에 침적시, 콘덴서(22)의 하면부에 형성한 돌출턱(24)에 의해 콘덴서(22)와 기판(16)은 일정한 간격을 가지고 있어, 220℃ - 240℃ 의 고온을 유지하는 납조의 열은 콘덴서(22)에 직접적인 영향을 주지 않게되고, 리드(18)를 통해 콘덴서(22)에 전해진 열은 돌출턱(24)에 의해 기판(16)으로 전해지게 되어 콘덴서(22)는 열에 의한 영향을 받지않게 된다.When immersed in the lead bath, the condenser 22 and the substrate 16 are spaced apart by the protrusions 24 formed on the lower surface of the capacitor 22, and the lead bath maintains a high temperature of 220 deg. C-240 deg. The heat does not directly affect the condenser 22, and the heat transmitted to the condenser 22 through the lead 18 is transmitted to the substrate 16 by the protruding jaw 24 so that the condenser 22 Will not be affected.
또한 침적이 끝난 후 콘덴서(22)에 남아 있는 열은 돌출턱(24)에 의해 급속히 방출된다.In addition, the heat remaining in the condenser 22 after the deposition is rapidly discharged by the projection jaw (24).
그러므로 전술한 바와 같은 본 고안의 돌출턱을 구비한 콘덴서는 기판(16)에 콘덴서(22)를 장착할 때 납조의 열이 콘덴서에 직접적으로 전달되지 않으므로 콘덴서의 오픈(open)불량을 방지하는 효과가 있다.Therefore, the condenser having the protruding jaw of the present invention as described above has an effect of preventing the open defect of the condenser because the heat of the lead bath is not directly transmitted to the condenser when the condenser 22 is mounted on the substrate 16. There is.
