来ている。Background of the Technology Multilayer printed circuit boards have traditionally been used in electronic devices such as communication devices and electronic computing devices to rationalize wiring and component mounting. This multilayer printed board has through-holes that are plated on the inner surface of the hole that penetrates the printed board to connect conductors between each layer. As the technology becomes more sophisticated, the number of through holes increases, and one printed board can now have thousands to tens of thousands of through holes.

On the other hand, the diameter of the pilot hole of the through hole is as narrow as 0.3 to 0.5 mm, and the required accuracy of the hole position is, therefore, a certain probability that the hole position will shift when machining a large number of holes. Conventionally, the only way to inspect this hole position shift was to apply a hole position inspection film to the hole after machining all the holes, but it took a lot of man-hours to inspect a large number of holes. There was a problem.

By providing a method for drilling holes in a printed board, which comprises placing a drill-destroying plate made of a metal plate or an insulating plate with holes on top of a printed board to be processed, and drilling the holes with a drill. achieved.
発明の実施例 以下、本発明実施例を図面によつて詳述する。Examples of the invention Embodiments of the present invention will be described in detail below with reference to the drawings.

を行なうのである。 In this embodiment, first, a drill breaking plate 2 is prepared. This drill breaking plate 2 is a metal plate or an insulating plate with holes drilled at positions corresponding to the hole positions of the printed board to be processed, and the hole 2a has a diameter D.
is defined as the predetermined hole diameter d (that is, the drill diameter) plus the tolerance for positional deviation, and the hole is drilled by etching, drilling, or the like. Next, this drill breaking plate 2 is aligned and placed on the printed board 4 to be processed. At this time, in order to prevent damage to the printed board 4 to be processed, it is preferable to insert an insulator or an entry metal 3 between the drill breaking plate 2 and the drill breaking plate 2.
Next, in this state, the hole is drilled using the drill 1.

えた孔は明けられないことになる。 When drilling this hole, if the drill 1 is within the allowable positional deviation range, the drill 1 passes through the hole 2a of the drill breaking plate 2 and drills the printed board 4 to be processed. If the drill 1 is misaligned beyond the permissible misalignment range, the tip of the drill 1 will come into contact with the hole 2a of the drill breaking plate 2 and break the drill itself, causing the hole in the printed board 4 to be processed. It will not be held in the morning. Therefore, holes exceeding the allowable range of positional deviation cannot be drilled.

とするといつた効果大なるものである。Effects of the Invention As explained in detail above, the printed board drilling method of the present invention uses a drill breaking plate that destroys a drill that is misaligned beyond the allowable positional deviation range. This has a great effect in that it is possible to prevent the drilling of holes that are misaligned by more than the allowable value.
