본 고안은 인쇄저항구조에 관한 것으로서, 더욱 상세하게는 인쇄저항을 인쇄도체상에 병렬로 디자인하여 인쇄저항 트리밍시 발생되는 저항값 불량을 제거할 수 있도록 한 인쇄저항구조에 관한 것이다.The present invention relates to a printing resistor structure, and more particularly, to a printing resistor structure designed to parallelly print printing resistors on a printed conductor so as to eliminate defects in resistance value generated when trimming the printing resistors.

일반적으로 인쇄기판등이 고집적화 되면서 저항성분을 인쇄저항으로 사용하고 있는바, 이러한 인쇄저항은 제1도(a)와 같이 등가적으로 표기할 수 있으며, (A1),(A2)는 인쇄도체를, (R)은 인쇄저항을 나타낸다.In general, as the printed board is highly integrated, a resistive component is used as a print resistance. Such a print resistance can be marked equivalently as shown in FIG. 1 (a), and (A1) and (A2) denote printed conductors. And (R) represent printing resistance.

제1도(b)는 기판(1)상에 인쇄도체(A1),(A2) 및 패드(P1),(P2)가 형성되고, 상기 인쇄도체(A1),(A2)에 인쇄저항(R)이 형성된 구성을 예시한다.In FIG. 1 (b), printed conductors A1, A2 and pads P1, P2 are formed on the substrate 1, and the print resistance R is formed on the printed conductors A1, A2. Illustrates a configuration in which) is formed.

이러한 인쇄저항(R)에 있어서의 저항값 조정은 원하는 저항치에 근접되도록 구성하고 예를 들어 점선화살표와 같이 일부를 트리밍시켜 저항값을 상승시킴으로써 원하는 저항값을 얻도록 한다. 이때 저항값은 통상식(:저항률, s : 단면적, ℓ : 길이)에 의해 단면적(s)에 반비례하고 길이(ℓ)에 비례하므로 트리밍하면 저항체의 길이가 길어지거나 단면적(s)이 줄어 저항값이 증가되는 이치를 이용한 것이다.The resistance value adjustment in the printing resistor R is configured to be close to the desired resistance value, and the desired resistance value is obtained by trimming a part such as a dotted arrow to increase the resistance value. At this time, the resistance value is expression( : Resistivity, s: Cross-sectional area, ℓ: Length) is inversely proportional to the cross-sectional area (s) and proportional to the length (ℓ). .

따라서 원하는 저항값을 얻기 위하여 상기 인쇄저항(R)을 화살표방향으로 트리밍하여 저항값을 조절하고 있으며, 저항값이 낮게 되었을 경우는 재 트리밍하여 원하는 저항값을 얻을 수 있으나, 저항값이 높게 트리밍되었을 경우는 재 트리밍하여 원하는 저항값을 얻는 것이 불가능하여 불량처리를 하고 있다. 즉, 인쇄저항(R)을 트리밍하여 얻은 저항값이 원하는 저항값보다 낮을 경우는 재 트리밍하여 원하는 저항값을 얻을 수 있지만 높을 경우는 원하는 저항값으로의 복원이 불가능하다는 단점이 있었다.Therefore, in order to obtain the desired resistance value, the printing resistance R is trimmed in the direction of the arrow to adjust the resistance value. When the resistance value is low, the resistance value can be trimmed again to obtain the desired resistance value, but the resistance value is trimmed high. In this case, it is impossible to obtain the desired resistance value by re-triming, which is a bad process. That is, if the resistance value obtained by trimming the print resistance R is lower than the desired resistance value, the desired resistance value can be obtained by re-triming, but when the resistance value is high, the desired resistance value cannot be restored.

본 고안은 이러한 점을 해결하기 위한 것으로, 인쇄저항을 기판상에 인쇄된 인쇄도체상에 병렬로 디자인함으로써 원하는 저항값보다 큰 저항값이 얻어질 경우 인쇄저항의 병렬연결로 저항값을 낮춘 후 재 트리밍하여 원하는 저항값을 얻을 수 있도록 한 인쇄저항구조를 제한함을 특징으로 한다.The present invention has been made to solve this problem. When the resistance is larger than the desired resistance by designing the printing resistance in parallel on the printed conductor printed on the substrate, the resistance is lowered by parallel connection of the printing resistance. It is characterized by limiting the print resistance structure so that the desired resistance value can be obtained by trimming.

즉, 하이브리드 IC등의 인쇄저항을 구성함에 있어서, 기판상의 인쇄도체상에 인쇄저항을 병렬로 배열하고, 상기 저항의 일측은 상기 인쇄도체를 통하여 패드에 공통 연결시키고 타측은 인쇄도체를 통하여 각각의 패드에 분리 연결시켜 저항값 불량시 상기 분리된 패드를 전기적으로 공통 연결시키고 상기 인쇄저항을 트리밍시켜 저항값을 조정하도록 한 것이다.That is, in forming a printed resistor such as a hybrid IC, the printed resistors are arranged in parallel on a printed conductor on a substrate, one side of the resistor connected to the pad through the printed conductor in common, and the other side of the printed resistor to the printed conductor. When the resistance is poor by connecting to the pad, the separated pad is electrically connected to the common, and the printing resistance is trimmed to adjust the resistance.

이하, 본 고안을 도면을 참조로 하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings.

제2도는 본 고안의 인쇄저항구조를 나타낸 것으로, 기판(1)상에 인쇄도체(A1),(A2),(A3) 및 대응패드(P1),(P2),(P3)가 일조를 이루어 분리 인쇄되고, 상기 인쇄도체(A1),(A2)및 인쇄도체(A1),(A3)상에 인쇄저항(R1),(R2)이 병렬로 인쇄되며, 상기 인쇄저항(R1),(R2)의 일측은 상기 인쇄도체(A1)에 연결되며 타측은 상기 인쇄도체(A2),(A3)를 통하여 패드(P2),(P3)에 각각 연결되어 상기 인쇄저항(R1),(R2)이 상호 분리된 구조이다.2 shows the printing resistance structure of the present invention, in which printed conductors A1, A2, A3 and corresponding pads P1, P2, and P3 are formed on the substrate 1; Separately printed, printed resistors R1, R2 are printed in parallel on the printed conductors A1, A2 and the printed conductors A1, A3, and the printed resistors R1, R2. One side is connected to the printed conductor A1 and the other side is connected to the pads P2 and P3 through the printed conductors A2 and A3, respectively, so that the print resistors R1 and R2 are It is a structure separated from each other.

상기와 같이 구성된 본 고안은 상기 인쇄저항(R1)을 트리밍하여 원하는 저항값을 얻었을 경우는 트리밍으로 상기 인쇄저항(R2)을 오픈시킨다. 즉, 상기 인쇄저항(R2)을 제2도의 화살표와 같이 트리밍하여 오픈시킨다.According to the present invention configured as described above, when the desired resistance value is obtained by trimming the print resistor R1, the print resistor R2 is opened by trimming. That is, the print resistor R2 is opened by trimming as shown by the arrow in FIG.

만일, 상기 인쇄저항(R1)을 트리밍하여 원하는 저항값보다 큰 값의 저항값이 되었을 경우에는 상기 패드(P2),(P3)를 트리밍 핀으로 연결시켜 상기 인쇄 저항(R1),(R2)이 전기적으로 병렬연결 되도록 하여 이 인쇄저항(R1),(R2)의 병렬저항연결 저항값()으로 저항값을 낮춘 후 재 트리밍하여 원하는 저항값으로 다시 높인다. 이때, 상기 패드(P2),(P3)는 부품 솔더링시의 솔더링으로 상호 연결된다.When the printing resistor R1 is trimmed to have a resistance value larger than a desired resistance value, the pads P2 and P3 are connected to the trimming pins, so that the printing resistors R1 and R2 are connected. The parallel resistance connection resistance values of the print resistors R1 and R2 After lowering the resistance value with), trimming it again, increase it again to the desired resistance value. At this time, the pads P2 and P3 are interconnected by soldering during component soldering.

이상에서 살펴본 바와 같이 본 고안은 종래에 인쇄저항을 디자인한 후 트리밍을 통하여 저항값을 조절하는 경우 저항값이 원하는 저항값 보다 클 경우 저항값의 복원이 불가능하여 인쇄저항을 불량처리하던 것을 인쇄도체상에 인쇄저항을 병렬로 디자인하여 저항값 불량시 인쇄저항이 전기적으로 병렬연결되도록 함으로써 저항값을 낮춘 후 재 트리밍하여 원하는 저항값을 얻을 수 있도록 한 것이다.As described above, in the present invention, when the resistance value is adjusted through trimming after designing the printing resistance in the related art, if the resistance value is larger than the desired resistance value, the resistance value cannot be restored and the print conductor has been poorly processed. By designing the printing resistance in parallel on the printed circuit, if the resistance is poor, the printing resistance is electrically connected in parallel so that the desired resistance can be obtained by lowering the resistance and then trimming it again.
