FIG. 2 is an explanatory diagram for explaining the structure of the matrix board.

As shown in FIG. 2(a), MB2 is composed of conductor layers of four printed wiring boards, each having multiple conductor layers in the X direction and Y direction from the first layer X (A) to the fourth layer Y (B). Through-holes are provided for each through-hole. The holes are provided at the same location in the vertical direction. 1st layer X (A) and 3rd layer X
In (B), through holes in the X direction are connected in a pattern, and in the second layer Y (A) and the fourth layer Y (B), through holes in the Y direction are connected in a pattern. These through holes are gold plated on the walls of each conductor layer, with an insulating layer separating the conductor layers, as shown in FIG. 2(b). When a connecting pin is inserted into this through hole as shown in FIG. 2(C), the two contact parts provided on the connecting pin connect the first layer

) and the fourth layer Y (B) are connected, allowing arbitrary connection from the X direction to the Y direction.

Normally, the first layer X (A) and the second layer Y (A) are used as the A line side of the communication line, and the third layer Use as a side.

Further, the X direction is used as an input level, and the Y direction is used as an output level.

By installing multiple stages of such MB2 and linking them, it is possible to create a distribution board with a multi-stage link structure, and furthermore, by automatically inserting the connecting pins using a robot, a wiring board with good workability and efficiency can be obtained. .
