Abstract

PROBLEM TO BE SOLVED: To prevent the contact with the front side end of a metallic core printed circuit board of a flat cable. SOLUTION: This turn table drive unit has the iron core printed circuit board 3 which is printed with the conductor patterns of the rotation control circuit of a motor 2 for driving the turn table 1 on its surface and a flat cable FC of which the terminal array 5 stripped of a coating at one end is connected and fixed to a terminal pad array 4 near the end edge of this circuit board 30 and of which the other end 6 is drawn around curvilinearly to the backside of a lifting base 7 placing the circuit board 3 and lifting this circuit board and is connected to a connector 8a. A double coated adhesive tape 40 is adhered to the region inner than the pad array 4 of the surface of the circuit board 30. The one end side of the cable FC is cambered and the curvilinear part 5a is adhered to the double coated adhesive and the terminal array 5 is fixed outward to the pad array 4 of the circuit board 30 by solder 9. The leading-out cable FC itself is elastically energized in the direction parting from the circuit board 30 as a result of the spring back by the curvilinear part 5a of the cable FC and, therefore, the cable hardly comes into contact with the sharp front side edge of the circuit board 30. The disconnection of the cable FC is thus prevented.

The elevating base 7 is adapted to perform an elevating operation by an actuator (not shown) along the guide column 7a. In order to minimize the tilt (surface inclination) of the disk surface, it is strongly required to control the flatness of the mounting surface (back surface) of the iron-core printed circuit board 3. Incidentally, the iron-core printed circuit board 3 is an iron-core printed wiring board in which an insulating layer 3b such as a resin or an enamel is applied on an iron-based core plate (base plate) 3a and a predetermined conductor pattern 4 is formed by printing. The iron core printed wiring board is a stamping press (punch) from the back side of a multi-core metal core printed wiring board in which a conductor pattern is repeatedly formed in a one-dimensional or two-dimensional direction and printed on the surface.
And obtained by shearing. Therefore, the back surface of the iron core printed circuit board 3 is the sag surface side. Note that a resist ink 11 is applied on the conductor pattern 4.

[0005] However, if the back surface of the iron-core printed circuit board 3 is a sagging surface, the front surface side necessarily has a fractured surface. This causes the curved portion R of the flat cable FC to easily come into contact with the burr X due to the vertical movement of the iron-core printed circuit board 3, and the flat cable FC may be disconnected.

When the elevating member moves up and down, the curved portion (bent portion) of the flat cable approaches and separates from the front edge of the metal-core printed circuit board, but one end of the flat cable is bent back. Since the flat cable is pulled out by the spring back by this part and is elastically urged in a direction away from the metal core printed circuit board, it is difficult to contact the front side edge of the metal core printed circuit board. Also, since one end side of the flat cable is bonded to the area inside the terminal pad row with a double-sided tape, the terminal displacement does not occur due to the temporary fixing state at the time of soldering the coating stripped terminal row to the terminal pad row, Connection failure and the like can be eliminated. Further, even after soldering, the flat cable is hardly peeled off due to the adhesive force of the double-sided adhesive tape.

Here, when the cable wound body inserted into the inner peripheral side of the fold at one end of the flat cable is fixed to the metal-core printed circuit board, the flat cable is bent at the fold. In addition to this, since the cable wound body blocks the spread of the tension, the peeling of the adhesive portion of the double-sided adhesive tape and the soldering portion can be prevented.

Then, in order to solve the second problem,
In the third means of the present invention, a predetermined number of conductive patterns are repeatedly separated in a one-dimensional direction or a two-dimensional direction by a punching press to separate a large number of sheets from the back surface of a multi-core metal core printed wiring board printed and formed on the front surface. In the method of manufacturing a metal core printed wiring board for obtaining the metal core printed wiring board of the above, before performing the punching press from the back surface of the multi-chamfered iron-based printed wiring board, the metal core printed wiring board is preliminarily adjusted to the perimeter of the single-chamfered punch. The method includes a step of performing a counterbore press on the surface of the chamfered metal-core printed wiring board. When the counterbore press is performed on the front surface, the surface edge is a sagged surface. Therefore, even if a punching press is performed from the back surface thereafter, the burrs and the like of the fractured surface fall within the plate thickness and do not protrude from the surface. The use of the metal core printed wiring board manufactured in this manner can prevent the flat cable from being disconnected.

Further, since one end side of the flat cable is adhered to the region inside the terminal pad row with a double-sided tape, when the stripped terminal row is soldered to the terminal pad row, a terminal displacement occurs due to the temporary fixing state. Without this, connection failures and the like can be eliminated. Further, even after soldering, the flat cable is hardly peeled off due to the adhesive force of the double-sided tape.
