본 고안은 인쇄저항구조체에 관한 것으로, 특히, 인쇄저항용 인쇄도체사이에 쇼트부를 일체로 형성하여 세라믹기판에 인쇄하고, 쇼트부 부위에 인쇄저항을 프린트함으로써, 인쇄도체의 크기를 소형화함과 동시에 인쇄저항과 쇼트된 인쇄도체 부위를 트리밍하여 원하는 저하값의 조절이 가능한 인쇄저항구조체에 관한 것이다.The present invention relates to a printed resistance structure, and in particular, by forming a short portion integrally between printed conductors for printing resistance, printing it on a ceramic substrate, and printing a print resistance on the short portion, thereby minimizing the size of the printed conductor and The present invention relates to a print resistance structure in which a desired reduction value can be adjusted by trimming print resistance and a shorted printed conductor portion.

일반적으로 인쇄저항은 제1도 (a)와 같이 약식 표기할 수 있으며, (A,B)는 인쇄도체를, (R)은 인쇄저항을 나타낸다.In general, print resistance can be abbreviated as shown in FIG. 1 (a), (A, B) denotes a printed conductor, and (R) denotes a print resistance.

제1도 (b)는 세라믹기판(11)에 인쇄도체(A,B)가 각각 인쇄되고, L자형 인쇄도체(A,B)의 수직부에 인쇄저항(R)이 인쇄된 구성으로, 화살표와 같은 방향으로 트리밍시킴을 나타낸 것이다. 또한, 제1도 (c)는 T형 인쇄도체(A,B)의 단부에 인쇄저항(R)이 인쇄된 구성으로 화살표와 같은 방향으로 트리밍시킴을 나타낸다.FIG. 1 (b) shows a structure in which the printed conductors A and B are printed on the ceramic substrate 11, and the print resistance R is printed on the vertical portions of the L-shaped printed conductors A and B. It shows trimming in the same direction. Also, FIG. 1 (c) shows trimming in the same direction as the arrow with the configuration in which the printing resistor R is printed at the ends of the T-type printed conductors A and B. FIG.

상기와 같은 경우, 인쇄저항(R)의 양단과 각각 접속되는 인쇄도체(A,B)는 인쇄저항(R)이 인쇄될 양단부에 대향하여 인쇄되도록 하는 구조를 가지며, 인쇄되는 인쇄저항(R)은 중간의 임의 개소에서 트리밍시켜 저항값을 조정한다.In this case, the printed conductors A and B respectively connected to both ends of the print resistor R have a structure such that the print resistor R is printed opposite to both ends to be printed, and the print resistor R to be printed. Is trimmed at an arbitrary position in the middle to adjust the resistance value.

일반적으로 트리밍에 있어서의 저항값 조정은 원하는 저항치에 근접되도록 구성하고 이를 트리밍시켜 저항값을 상승시킴으로써 원하는 저항을 조정한다. 이때의 저항값 조정은 제1도 (b) 및 (c)의 경우와 같은 저항값을 통상로 표기할 수 있기에 트리밍하면 저항체의 길이(ℓ성분)가 길어지므로(커지므로), 저항값이 증가되는 이치를 이용한 것이다.In general, the resistance value adjustment in trimming is configured to be close to the desired resistance value, and the desired resistance value is adjusted by trimming the resistance value. Adjusting the resistance value at this time usually uses the same resistance value as in the case of FIGS. 1 (b) and (c). Since the trimming increases the length (l component) of the resistor (larger), it uses the value that the resistance value increases.

그러나 상기와 같은 종래의 인쇄저항구조는, 인쇄저항의 크기에 따라 인쇄도체(A,B)의 간격이 설정되어 세라믹기판에 각각 프린트됨으로써, 인쇄도체(A,B)의 크기가 커지게 되어 세라믹기판의 면적이 커지게 되고, 또한, 인쇄도체(A,B)의 프린팅이 복잡해지는 문제점이 있었다.However, in the conventional print resistance structure as described above, the gap between the print conductors A and B is set according to the size of the print resistors and printed on the ceramic substrate, thereby increasing the size of the print conductors A and B. There is a problem that the area of the substrate becomes large and the printing of the printed conductors A and B becomes complicated.

본 고안의 목적은, 상기와 같은 종래의 문제점을 해소하기 위한 것으로, 특히, 인쇄도체 사이에 쇼트부를 일체로 형성하고, 인쇄도체와 일체로 형성된 쇼트부에 인쇄저항을 프린트한후, 상기 쇼트부 및 인쇄저항을 레이저를 이용하여 절삭가공하여 트리밍시킴으로써, 원하는 저항값을 조정하고 프린트기판의 면적을 줄이게 되는 인쇄저항구조체를 제공하는데 있다.An object of the present invention is to solve the above-mentioned conventional problems, and in particular, after forming a short part integrally between printed conductors and printing a printing resistance on the short part formed integrally with the printed conductor, the short part And trimming the printed resistor by using a laser to adjust the desired resistance value and to reduce the area of the printed board.

상기와 같은 목적을 달성하기 위한 본 고안 인쇄저항구조체는, 세라믹기판(11)의 표면에 프린트된 A'부분과, 상기 A'부분의 일측에 일체로 형성된 쇼트부(10)와, 상기 쇼트부(10)의 다른 일측에 일체로 형성된 B'부분을 구비하는 인쇄도체와, 상기 A'부분과 B'부분의 사이에 일체로 형성된 쇼트부(10)의 임의의 위치에 프린트되며, 레이저를 사용하여 상기 쇼트부(10)와 함께 동시에 상하방향으로 절삭가공하여 1회 이상에 걸친 트리밍에 의해 원하는 저항값을 가지게 되는 인쇄저항(R)을 구비하여 하이브리드 IC의 인쇄저항을 구성함을 포함하여 구성됨을 그 기술적 구성상의 특징으로 한다.The present invention print resistance structure for achieving the above object, A 'portion printed on the surface of the ceramic substrate 11, the short portion 10 formed integrally on one side of the A' portion, and the short portion A printed conductor having a portion B 'formed integrally on the other side of the part 10, and printed at an arbitrary position of the shot portion 10 formed integrally between the portion A' and the portion B ', using a laser And a printing resistor (R) having a desired resistance value by trimming over one or more times by simultaneously cutting in the vertical direction together with the short portion (10), and configuring the printing resistance of the hybrid IC. It is characterized by the technical configuration.

이하 본 고안의 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the drawings of the present invention.

제2도 (a)-(d)는 본 고안의 여러 예시드를 도시한 것으로, 인쇄도체(A',B') 사이에 쇼트부(10)를 인쇄도체(A',B')와 일체로 형성하고, 쇼트부(10)의 임의 개소에 인쇄저항(R)을 인쇄시키며, 상기 인쇄저항(R)과 쇼트부(10)를 레이저를 이용하여 동시에 절삭가공하여 트리밍시켜 저항값을 조정토록 한다.2 (a)-(d) show various examples of the present invention, in which the short portion 10 is integrated with the printed conductors A 'and B' between the printed conductors A 'and B'. And print the print resistance R at any position of the short portion 10, and simultaneously trim and cut the print resistance R and the short portion 10 using a laser to adjust the resistance value. do.

이 경우 인쇄저항(R)은 제2도 (a)-(c)와 같이 단일 인쇄저항으로 구성할 수도 있고, 제2도 (d)와 같은 복수로 구성할 수도 있다.In this case, the printing resistor R may be composed of a single printing resistor as shown in Figs. 2 (a) to 2 (c), or may be formed of plural as shown in Figs.

물론 저항값을 조정할 경우에는 역시식에 따라 트리밍시킴에 의해저항값이 증가하게 동시에 인쇄도체(A',B')의 사이에 일체로 형성된 쇼트부(10)와 인쇄저항(R)을 레이저를 이용하여 동시에 절삭가공하여 트리밍시킴에 따라 상호도통되어 있던 인쇄도체(A',B')가 분리되게 된다.Of course, when adjusting the resistance value In accordance with the formula, the resistance value increases by trimming, and simultaneously, the short part 10 and the printing resistance R formed integrally between the printed conductors A 'and B' are simultaneously cut and trimmed using a laser. In accordance with this, the printed conductors A 'and B' which are electrically connected to each other are separated.

특히, 제2도 (d)의 경우는 쇼트부(10)의 중앙 부위가 새로운 인쇄도체(A',B')를 이루며 두 개의 인쇄저항(R)이 이루어질 수 있게 된다. 즉, 여러개의 저항을 필요로 할 경우에는 본 고안의 구조를 이용하여 여러 저항을 단순한 트리밍으로 제조 가능하여 공정이 간단해진다.In particular, in the case of FIG. 2 (d), the center portion of the short part 10 forms new printed conductors A ′ and B ′ and two printing resistors R may be formed. In other words, when a plurality of resistors are required, the process can be simplified by simply trimming the various resistors using the structure of the present invention.

이상에서 살펴본 바와 같이 본 고안은, 특히, 인쇄도체 사이에 쇼트부를 인쇄도체와 일체로 형성하여 세라믹기판에 인쇄하고, 이에 인쇄저항을 인쇄시킨 다음 인쇄저항과 쇼트부를 동시에 트리밍하여 전기적으로 인쇄도체를 분리시킴으로써, 인쇄도체의 인쇄가 용이하고, 세라믹기판의 공간이 절약되는 효과가 있는 것이다.As described above, the present invention, in particular, the short portion between the printed conductors are formed integrally with the printed conductors to be printed on the ceramic substrate, and the printed resistances are printed on them, and then the printed resistors and the short portions are simultaneously trimmed to electrically print the printed conductors. By separating, the printing of the printed conductor is easy, and the space of the ceramic substrate is saved.
