ビンのＩＣと同様の構成となっている。As shown in FIG. 4, a surface mount type network resistor normally has eight resistance elements 2 formed on a substrate (not shown), and each resistance element 2 connected to a lead terminal 5.
It has the same configuration as the bottle IC.

場合内層で接続する方法がとられる。As shown in FIG. 5, there is an IC9 on the printed circuit board 101.
, chip components 7 and 8, and a network resistor 6a shown in FIG. 4 are mounted. Now, when making a pattern connection to connect the chip component 7 and the chip component 8, wiring is performed on the mounting surface using the pattern 15 due to restrictions due to the existing needle pattern connected to the network resistor 6a and IC 9 and the mounting component itself. or through hole 14
In the case of a multilayer printed circuit board, a method is used in which connection is made using the solder surface pattern 13 or an inner layer in the case of a multilayer printed circuit board.

を困難にする。In the former case, when the pattern is routed around the mounting surface, it becomes difficult to form other pattern wiring, and in the latter case, when through holes are used, the wiring space is reduced, making the mounting design difficult.

時にプリント基板製作工程も複雑となり製作日数がかか
るという欠点がある。The conventional network resistor described above is usually used as an electrical pull-up resistor, so pattern wiring from ICs and LSIs mounted on printed circuit boards is concentrated, making it difficult to implement in high-density packaging. This made the design difficult. In particular, the surface mount method has a high rate of wiring only on one side of the printed circuit board because the chip components are adjacent to each other, and compared to the conventional through-hole printed circuit board, the pattern wiring space and pattern path are smaller, and the mounting design time is increased. 2 in a through-hole printed circuit board instead of
What could be designed with layers cannot be designed with anything other than 4 or 6 layers, which has the drawback that the price of the printed circuit board itself increases, and at the same time, the printed circuit board manufacturing process becomes complicated and takes many days to manufacture.
