この発明はフレキシブルプリント板の折曲げ加工方法に

により折曲げ状態を維持す−る。In recent years, so-called flexible printed boards (hereinafter abbreviated as FPC), in which conductor circuits are printed on the surface of a base film made of polyester or polyimide, have been widely used. There may be cases where it is necessary to bend the material. For example, when performing a bending process as shown in Figure 1, the FP
Bend the end of CI to form a bent part 1a, insert a reinforcing plate 2 inside this bent part 1a, and glue the inner surface lc of the bent part 1a on both sides of this reinforcing plate 2 with adhesive 8. The bent state is maintained by gluing.

産性が良好でなく、またコスト高となる欠点があった。By the way, F'PCI generally has a strong repulsive force against bending, and in particular, double-sided FPCs with circuits formed on both sides will peel off within a short period of time when bonded with a room temperature pressure type adhesive. . For this reason, bonding is performed by applying pressure and heating using a thermal crosslinking type adhesive. However, such bonding methods not only require a hot plate press at high temperature and high pressure, but also have the disadvantage that the crosslinking process is long, resulting in poor productivity and high costs.
この発明は上記の事情に鑑み、極めて簡単な加工装置で
短時間の内にＦＰＣの折曲げ加工をすることのできるＦ
ＰＣの折曲げ加工方法を提供するものである。In view of the above-mentioned circumstances, this invention is an FPC that can bend an FPC in a short time using extremely simple processing equipment.
This provides a method for bending a PC.
以下、図面を参照して本発明の詳細な説明する。Hereinafter, the present invention will be described in detail with reference to the drawings.

Ｐ ＣＩの折曲げ加工を行うには次の手順による。In this figure, the wound is a heater. This heating i4 consists of a prismatic heating body 4a, a heater 3b built into the heating body 4a, and a heat insulating material 4c on three sides eM of the heating body 4a. The heating element 4a has a lacrimality on the bale surface of 300°C to 3.
It is kept at 50°C.
4. Li” due to such heater scratches.
The following procedure is used to bend the PCI.
■ ＦＰＣＩを適当な押えｆ５で折曲げ、折曲げ部１ａ
の内面ＩＣと補強板２とを押圧して接着剤８で接着する
。■ Bend the FPCI with a suitable presser foot f5 and press the bent part 1a.
The inner surface IC and the reinforcing plate 2 are pressed and bonded together with an adhesive 8.
■ 次に、＠２図に示すように折曲げ部１ａのわん曲面

３０−．４０秒の回加熱する。■Next, as shown in Figure @2, the heating body 4 of the heater 4 is attached to the curved surface 1d of the bent portion 1a. Apply pressure by pressing a for about 30 minutes. Heat for 40 seconds.
このような処理により、折曲げ部１ａのわん曲面１ｄが
加熱変形され、反撥力が消滅する。これによって折曲げ
部１ａの内面ＩＣと補強板２とは剥離することがなく、
折曲げ部ｌａは長期に渡つて変形することがない。Through such processing, the curved surface 1d of the bent portion 1a is heated and deformed, and the repulsive force is eliminated. As a result, the inner surface IC of the bent portion 1a and the reinforcing plate 2 do not separate, and
The bent portion la does not deform over a long period of time.

It will be done. Furthermore, since expensive equipment is not required, processing costs can be reduced.
