Description

  The present invention relates to a panel plating jig, and more particularly to a panel plating jig that can be securely mounted without causing deflection when performing through-hole plating of a sheet-like thin printed wiring board. is there.

  Conventionally, in the through-hole plating of a thin printed wiring board, plating is sometimes performed in a web state, but in the case of a configuration in which two single-sided flexible printed wiring boards are bonded, plating is performed in a sheet state. In recent years, there has been a tendency to reduce the thickness of the product itself, and when plating is performed in a sheet state, the sheet must be mounted on a plating jig.

  The sheet-like thin printed wiring board formed with a small thickness may bend when the jig is mounted. In this case, the bent portion is wrinkled in the wavy state due to the vibration of the plating solution. If wrinkles are formed on a thin printed wiring board, plating may be defective and the inside of the apparatus may be clogged in the circuit forming process. Further, when the mounting to the jig is incomplete, the thin printed wiring board is detached from the panel plating jig due to aeration during plating, and the thin printed wiring board falls into the plating solution.

  A holding jig that can be easily held in a state in which a plane holding force (tension) is applied to a plate material such as a printed wiring board is a jig that suspends a non-processed plate material vertically, and the non-processed plate material The upper and lower frame plates are longer than one side and provided with rotatable clamps in the vicinity of both ends, and the rotatable clamps arranged on the upper and lower frame plates are respectively inclined to the inside. The upper and lower corners of the non-treated plate material are sandwiched in the vicinity of each corner, and the clamps are rotated so that the clamps open to the outside due to the weight of the non-treated plate material and the lower frame plate. There is known a configuration for holding in such a state (see, for example, Patent Document 1).

In addition, the board holding pin is inserted into the board's incoming hooks on the left and right sides of the vertical frame of the board holding frame to lock the board, and the board locking pins that are connected to the power supply and receive power for plating on the board are moved up and down. The board locking pin is formed by curling the elastic wire so that it can be elastic in the direction opposite to the locking direction, and the tip of the board locking pin is locked in the locking direction. A plating substrate holder that has a current-carrying part that protrudes in the opposite direction, a slit that is large enough not to pass through the incoming hole in the board before the current-carrying part, and that has a non-conductive coating except for the current-carrying part Is also known (see, for example, Patent Document 2).

  In the invention described in Patent Document 1, a clamp for fixing a non-processed plate material such as a printed wiring board is movable outward, and a plane holding force (tension) is applied without forming a hole or the like in the plate material. Although the plate material is to be held in a state, there is a problem that the configuration is complicated and the cost is high.

  In the invention described in Patent Document 2, the board locking pin secures energization to the board and also has a function of correcting sagging and wrinkles of the board. However, when the board is thin, the board locking pin is inserted. When pulled up and down, the hole is deformed or cracked, and slack and wrinkles cannot be corrected. In addition, when inserting the locking pin into the hole, the locking pin has to be aligned, and workability is poor.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a panel plating jig capable of correcting a slack or wrinkle of a thin printed wiring board and mounting the thin printed wiring board with a simpler configuration.

  The present invention has been proposed to achieve the above object, and the invention according to claim 1 is a sheet-like thin printed wiring comprising a frame support and a shielding plate that can be opened and closed with respect to the support. In a panel plating jig for vertically sandwiching a plate, the support column and the shielding plate are provided with protrusions made of an elastic body in contact with at least four corners of the thin printed wiring board, and the support column and the shielding plate are printed with a thin object. There is provided a panel plating jig characterized in that when the wiring board is sandwiched, the protrusions are formed so as to press-contact the thin printed wiring boards in the direction of pulling the thin printed wiring boards outward from the four corners.

  According to this configuration, when a thin printed wiring board is mounted on a panel plating jig composed of a support and a shielding plate, the thin printed wiring board is disposed vertically between the support and the shielding plate to close the shielding plate. Then, the protrusions provided on the support column and the shielding plate come into contact with the four corners from both sides of the thin printed wiring board, and the respective protruding parts are pressed in the direction of pulling the four corners of the thin printed wiring board outward.

  As described above, since the thin printed wiring board is pulled toward the outer four corners, even if the thin printed wiring board mounted on the panel plating jig has a slack, the slack is eliminated by the pulling. Therefore, wrinkles can be prevented from occurring on the thin printed wiring board.

  According to a second aspect of the present invention, in the panel plating treatment according to the first aspect, the protrusions are obliquely arranged so that the heights of the respective leading end portions gradually increase in the four corner directions of the thin printed wiring board. Provide ingredients.

  According to this configuration, since the tip portions of the protrusions are obliquely arranged so as to gradually increase in the four corner directions, when the thin printed wiring board comes into contact with the protrusion portions, the respective tip portions bend in the outer four corner directions, Pull the four corners of the thin printed circuit board outward and pinch them from both sides.

  A third aspect of the present invention provides the panel plating jig according to the first aspect, wherein each of the protrusions is provided such that each tip portion is inclined toward the four corners of the thin printed wiring board.

  According to this configuration, since the protrusions are provided so as to incline toward the four corners, when the thin printed wiring board comes into contact with the protrusions, the respective leading ends bend toward the outer four corners, and the thin printed wiring board Pull the four corners outward and pinch them from both sides.

  The panel plating jig of the present invention is provided with protrusions made of an elastic body on the support and the shielding plate, and when the panel plating jig sandwiches the thin printed wiring board, the respective protrusions are from both sides of the thin printed wiring board. Since it is pulled and pinched in the direction of the outer four corners, the slack of the thin printed wiring board is eliminated, and the generation of wrinkles on the thin printed wiring board can be prevented.

  In this way, it is possible to prevent clogging in the apparatus due to defective plating or a circuit formation process. In addition, since the thin printed wiring board is securely attached to the panel plating jig, it does not come off the jig and fall into the plating solution.

  The panel plating jig according to the present invention will be described below with reference to preferred examples. In order to achieve the object of correcting the slack and wrinkles of a thin printed wiring board with a simpler configuration and allowing the thin printed wiring board to be mounted, the present invention provides a frame column and a column. In a panel plating jig for vertically holding a sheet-like thin printed wiring board with a shield plate that can be freely opened and closed, the support and the shielding plate are each in contact with at least four corners of the thin printed wiring board. This is realized by providing a protruding portion made of a body and pressing the thin printed wiring board in the direction of pulling the thin printed wiring board to the outside of the four corners when the support column and the shielding plate sandwich the thin printed wiring board. .

  FIG. 1 is a front view of a panel plating jig 10 of the present invention. The main member of the panel plating jig 10 formed on the frame is a support column 11 made of a pair of left and right conductive members, and the upper and lower sides of the support column 11. The support 11 is immersed in the plating solution while holding the both sides of the thin printed wiring board 13 so as to sandwich the thin printed wiring board 13 and feeds the thin printed wiring board 13 as a cathode. It is formed to do.

  A plate-like shielding plate 14 is attached to each of the support columns 11 so as to be opened and closed in the left-right direction. The shielding plate 14 extends to cover the upper and lower ends of the thin printed wiring board 13 up to the central portion at the upper and lower portions. 14 a and 14 b are formed, and an opening 14 c is provided in the middle of the shielding plate 14. In addition, holes 14d, 14d,... The shielding plates 14 are respectively attached to the front and rear surfaces (the front side and the back side of the drawing) of the panel plating jig 10.

  The support 11 is provided with a contact 15 at a predetermined position, and the shielding plate 14 corresponding to the contact 15 is located at a position facing the contact 15 of the support 11 when the shielding plate 14 is closed to the support 11. A contact 16 is provided. Further, the support column 11 and the shielding plate 14 are provided with protruding portions 20 made of an elastic body that are in contact with at least four corners of the thin printed wiring board 13.

  2 and 3 are side views of the main part showing a cylindrical protrusion 20A as an example of the protrusion. As shown in FIG. 2, a thin printed wiring board is provided between the support 11 and the shielding plate 14. As shown in FIG. 13 are arranged vertically, and the columnar projections 20A are provided on the support column 11 and the shielding plate 14 at four positions respectively in the vicinity of the four corners of the thin printed wiring board 13.

  The protrusions 20A are attached so as to protrude substantially perpendicularly from the surfaces of the support column 11 and the shielding plate 14, and the heights of the respective tip portions 21A gradually increase in the four corner directions (arrow C direction) of the thin printed wiring board 13. The tip portion 21A is an inclined surface. The material of the protrusion 20A is formed of an elastic body having chemical resistance, for example, a synthetic rubber material such as fluorine rubber or acrylic rubber.

  As shown in FIG. 3, when the shielding plate 14 is closed, the distance between the support 11 and the shielding plate 14 is narrowed, and the tip 21A of the protrusion 20A provided on the support 11 and the shielding plate 14 is a thin print. The wiring board 13 comes into contact with the four corners from both sides. Since the tip 21A of each projection 20A is an inclined surface that gradually increases in the four corner directions (arrow C direction), the tip 21A bends in the four corners, and the tip 21A of each projection 20A is a thin printed wiring. While pressing in the vicinity of the four corners of the board 13, the four corners of the thin printed wiring board 13 are pulled outward to sandwich the thin printed wiring board 13 from both sides.

  Thus, since the thin printed wiring board 13 is pulled in the outer four corner directions (arrow C direction), even if there is a slack in the thin printed wiring board 13 attached to the panel plating jig 10, the slack is caused by the pulling. Is resolved. Therefore, wrinkles can be prevented from occurring on the thin printed wiring board 13.

  The protrusions 20B are provided so as to be inclined from the surfaces of the support column 11 and the shielding plate 14 in the four corner directions (arrow C direction), respectively. The material of the protrusion 20B is formed of an elastic body having chemical resistance, for example, a synthetic rubber material such as fluorine rubber and acrylic rubber, similar to the protrusion 20A. In addition, although the shape of the front-end | tip part 21B of this projection part 20B is the circular end surface which cut | disconnected the cylinder to the horizontal direction, other arbitrary shapes may be sufficient.

  As shown in FIG. 5, when the shielding plate 14 is closed, the interval between the support 11 and the shielding plate 14 is narrowed, and the protrusions 20 </ b> B provided on the support 11 and the shielding plate 14 are arranged on both sides of the thin printed wiring board 13. To the vicinity of the four corners. Since each projection 20B is inclined in the four corner directions (arrow C direction), the tip 21B is bent in the four corners, and the tip 21B of each projection 20B is pressed against the vicinity of the four corners of the thin printed wiring board 13. The thin printed wiring board 13 is clamped from both sides by pulling the four corners of the thin printed wiring board 13 outward.

  Thus, since the thin printed wiring board 13 is pulled in the outer four corner directions (arrow C direction), even if there is a slack in the thin printed wiring board 13 attached to the panel plating jig 10, the slack is caused by the pulling. Is resolved. Therefore, wrinkles can be prevented from occurring on the thin printed wiring board 13.
