본 발명은 탄탈 전해 콘덴서의 열풍장치를 이용한 솔더링 방법에 관한 것으로, 더욱, 상세하게는 탄탈 전해 콘덴서의 제조시 탄탈소자의 플럭스(flux) 도포후 솔더링(soldering)을 실시하는 공정의 중간에 열풍장치를 사용함으로서 탄탈소자를 건조시키는 공정이 삽입되는 솔더링 방법에 관한 것이다.The present invention relates to a soldering method using a hot air device of a tantalum electrolytic capacitor, and more particularly, to a hot air device in the middle of a process of performing soldering after flux coating of a tantalum element during manufacture of the tantalum electrolytic capacitor. The present invention relates to a soldering method in which a process of drying a tantalum element is inserted.
일반적으로 탄탈 전해 콘덴서를 제조하는데 있어서 반제품인 탄탈소자를 플럭스(flux)에 침적한 후에는 솔더링 공정을 실시한다.In general, in manufacturing a tantalum electrolytic capacitor, after the tantalum element, which is a semi-finished product, is deposited on a flux, a soldering process is performed.
제1도는 종래의 실시예에 따른 탄탈 전해 콘덴서의 솔더링 방법을 도시하는 도면으로, 도면(a)에서 음극리드(12)와 양극리드(14)를 구비하는 탄탈소자(10)는 탄탈 전해 콘덴서의 반제품으로서 플럭스(18)에 침적된다.FIG. 1 is a view illustrating a soldering method of a tantalum electrolytic capacitor according to a conventional embodiment. In the drawing (a), a tantalum element 10 having a cathode lead 12 and an anode lead 14 is formed of a tantalum electrolytic capacitor. It is deposited on the flux 18 as a semifinished product.
상기의 플럭스(18) 도포는 플럭스조(16)의 상하 운동으로 실시하며 제1도의 도면(b), (c)와 같이 납조(20)에 침적하기 전까지 대기 상태로 위치한다.The flux 18 is applied by the vertical movement of the flux tank 16 and is placed in the standby state until it is deposited in the lead bath 20 as shown in FIGS. 1B and 1C.
이후 탄탈소자(10)는 200℃의 온도를 갖는 납조(20)의 이동으로 침적되어 탄탈소자(10)의 외주에 솔더링을 실시한다.Thereafter, the tantalum element 10 is deposited by the movement of the lead bath 20 having a temperature of 200 ° C. to solder the outer periphery of the tantalum element 10.
그러나 전술한 바와같은 종래의 탄탈소자에 대한 솔더링 방법에는 하기와 같은 문제점이 발생한다.However, the following problems occur in the conventional soldering method for the tantalum element as described above.
첫번째로, 플럭스(18)에 침적된 탄탈소자(10)는 액체 상태의 플럭스(18)를 외주에 도포한 후 대기 상태에서 바로 200℃의 고온 납조(20)에 침적되므로 탄탈소자(10)에 대한 상기 플럭스(18)의 불충분한 건조로 고온의 납(22)에 침적시 상기 플럭스(18)가 부분적으로 증발하는 문제점이 생긴다.First, the tantalum element 10 deposited on the flux 18 is applied to the tantalum element 10 because the flux 18 in the liquid state is applied to the outer circumference and then deposited in the high temperature solder bath 20 at 200 ° C. immediately in the atmospheric state. Insufficient drying of the flux 18 results in a partial evaporation of the flux 18 upon deposition on hot lead 22.
또한, 상기의 고온 납조(20)에 대한 탄탈소자(10)의 침적시 고온에서의 솔더링공정의 열충격은 플럭싱(fluxing) 효과를 감소시켜 납땜을 불량하게 하며, 탄탈소자(10)의 표면을 거칠게하여 제조공정을 마친 탄탈 전해 콘덴서의 중요 특성을 저하시키는 문제점이 있다.In addition, the thermal shock of the soldering process at a high temperature when the tantalum element 10 is deposited on the high temperature solder bath 20 decreases the fluxing effect, thereby causing poor soldering, and the surface of the tantalum element 10. There is a problem of reducing the important characteristics of the tantalum electrolytic capacitor which is roughened and finished the manufacturing process.
따라서 본 발명은 전술한 문제점을 해결하기 위해 창출한 것으로, 본 발명의 목적은 급작한 온도변화에 대한 열충격을 감소시키고, 탄탈소자의 플럭스의 증발로 인한 납땜 불량이 발생하지 않도록하는 열풍장치를 공정에 삽입하는 탄탈 전해 콘덴서의 열풍장치를 이용한 솔더링 방법을 제공함이다.Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to reduce the thermal shock against sudden temperature changes, and to process a hot air device to prevent solder failure due to evaporation of the flux of the tantalum element. It provides a soldering method using a hot air device of a tantalum electrolytic capacitor inserted into the.
전술한 목적을 달성하기 위한 본 발명은 탄탈소자를 플럭스에 침적시킨 후 대기상태에서 솔더링을 실시하는 솔더링 방법에 있어서, 상기 플럭스에 침적한 후의 탄탈소자에 블로우 팬 모터가 전기히터의 열을 고르게 분산함으로서 예열시켜주는 한편 이때의 온도는 온도센서와 일정온도 범위를 지정하는 온도제어기에 의해 제어되는 열풍장치를 이용하여 상기 플럭싱된 탄탈소자를 건조 및 예열한 후 솔더링하는 것을 특징으로 하는 탄탈 전해 콘덴서의 열풍장치를 이용한 솔더링 방법을 제공하여 준다.The present invention for achieving the above object is a soldering method in which the tantalum element is deposited on the flux and then soldered in the standby state, wherein a blow fan motor distributes heat of the electric heater evenly to the tantalum element after the flux is deposited. The pre-heating is performed while the tantalum electrolytic capacitor is soldered after drying, preheating and soldering the fluxed tantalum element using a hot air device controlled by a temperature sensor and a temperature controller specifying a predetermined temperature range. It provides a soldering method using the hot air device of.
이하에서는 첨부한 도면을 참조하여 본 발명의 양호한 일실시예에 따른 탄탈 전해 콘덴서의 열풍장치를 이용한 솔더링 방법을 상세히 설명하기로 한다.Hereinafter, a soldering method using a hot air device of a tantalum electrolytic capacitor according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
