Next, when setting the cutting conditions, as shown in No. 5-, the cutting area of the printed board 1 has lands 6, through holes 5,
Since the through-hole reinforcement lands are made of copper materials, the TS materials made of glass epoxy resin, etc., and the solder 9 that connects the bottles and through-holes, each with different properties is assembled. , the detection of the one-turn torque value becomes decisive. The reason for setting the conditions according to this example is that 1ilaiL was obtained from preliminary experiments, and the rotation speed was 250 rpm.
For M or less, the blade 15 of the bit 14 is likely to wear out, and 1
For 500 r 11M or more, cutting heat will cause the 7th
As shown in the decoy, chip burn-in 22 occurs on the cut surface.

In addition, the cutting time is as follows: The thinner the wall thickness of the bit 14 is, the higher the general torque value must be.
It takes about 20 minutes for a wall thickness of 0.5 and about 10 minutes for a wall thickness of 02.Insulating and fixing the r-O through-hole requires an extra cost due to reliability, but for the insulation of a 1-hole, it takes about 10 minutes for a wall thickness of 02. It is necessary to use adhesive tape 24 and adhesive 25t' and apply it by capillary action to prevent leakage.

As described above, according to the present invention, there is a hollow cylindrical inner layer which is cut by a p-through holener with a cutting blade while storing a connector bin in the hollow part, and a conductor between the connector bin and the inner layer by a cutting bit. By removing the holes (through holes, solder, etc.), it is possible to easily cut the internal parts of the multilayer printed product.
