For example, a strip made of a conductive material is molded, a predetermined number of groups of terminal strips are sequentially formed on the strip at equal pitches in the longitudinal direction, and integrated circuit elements are sequentially connected and fixed to each group of terminal strips. There is a way to install it in such a way. The integrated circuit element with the terminal piece attached in this way is cut and separated from the strip at the base of the terminal and sent to the next inspection process, where a functional test is performed to determine whether it operates normally. was.

In this inspection process, defective products are removed, and the remaining normal integrated circuit elements are collectively managed.

(Problems to be Solved by the Invention) However, when testing separated integrated circuit elements in this way, the integrated circuit elements must be fed to the testing equipment in a predetermined posture, and the feeding equipment is complicated and It was expensive and not very desirable. Moreover, when integrated circuit elements are managed separately in this way, there is a problem that component management is not easy.

In addition, although there have been conventional electronic component automatic assembly equipment that assembles integrated circuit elements whose components have been managed in this way onto printed circuit boards, when supplying integrated circuit elements to an electronic component automatic assembly equipment, integrated circuit elements Since it is necessary to line up the materials in a predetermined posture and supply them, the device for supplying them is also complicated and expensive, which is not desirable.

Therefore, the present invention provides a method for manufacturing a hoop material with integrated circuit elements, which allows easy component management of integrated circuit elements and facilitates the supply of integrated circuit elements to inspection equipment and automatic electronic component assembly equipment. The purpose is to provide

(Means for Solving the Problems) In order to achieve this object, the present invention provides a method in which a predetermined number of terminal strip groups are integrally formed at equal pitches in the longitudinal direction, and are integrated into each terminal strip group. After providing a band-shaped body made of a conductive material to which circuit elements are connected and fixed to each other, and cutting and separating the functional terminals other than the ground terminal or idle terminal from the base of the band-shaped body side among the terminal piece groups, each of the terminals is separated. A method for manufacturing a hoop material with an integrated circuit element is characterized in that a functional test is sequentially performed on each of the integrated circuit elements using a group of pieces, and integrated circuit elements determined to be defective by the test are removed from the strip. That is.

(Function) By supplying the hoop material with integrated circuit elements formed by this method to the electronic component supply apparatus, the integrated circuit elements are sequentially supplied to the electronic component supply apparatus in a predetermined posture. A device for placing the element in a predetermined posture is not required. In addition, since the hoop material with integrated circuit elements is formed by attaching only non-defective integrated circuit elements to the strip, it is easy to manage the large number of integrated circuit elements.

(Example) Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, a portion (not shown) of a strip 1 made of a conductive material that is continuous to the left side of the drawing is attached in a rolled state to a material supply device (not shown).

This rolled strip 1 is first intermittently supplied to a press punching device 2 from a material supply device.

This press punching device 2 sequentially forms a predetermined number of terminal pieces 3 on one side of the strip 1 at equal pitches in the longitudinal direction.

As shown in FIG. 2, this terminal piece group 3 is composed of left and right ground terminal pieces 4, 5 and a central functional terminal piece 6, 7, 8.9.

The terminal strip group 3 of the strip-shaped body 1 formed in this way is sent to a terminal connecting device 10, and this terminal connecting device 10 connects the ground terminal strips 4, 5 and the functional terminal strips 6, 7, 8, 9 to an integrated circuit. It is crimped and soldered to a predetermined portion of the element 11.

This integrated circuit element 11 and the terminal strip group 3 to which it is attached are supplied to a terminal cutting/separating device 12, and this terminal cutting/separating device 12 is configured to operate the functional terminal strips 6, 7 of the terminal strip group 3 as shown in FIG. , 8.9 are cut and separated from the strip 1 at the base portion. In this state, the integrated circuit element 11 is supported by the strip 1 by the left and right ground terminal pieces 4 and 5, so that twisting of the strip 1 is less likely to occur.

=4= The terminal strip group 3 and the integrated circuit element 11 from which the functional terminal strips 6, 7, 8.9 have been cut in this manner are supplied to the inspection device 13. After this inspection bag [13 has brought the contacts 14, 15, 16, 17, 18 into contact with the strip 1 and the functional terminal pieces 6, 7, 8.9, the central processing unit 19 and the input/output bag W2
0, it is checked whether the integrated circuit element 11 is operating normally.

The central processing unit 19 of this inspection device 13 is
It is determined whether the integrated circuit element 11 is a good product or a defective product, and the result is displayed on a display 21. Here, integrated circuit element 1
1 is determined to be a defective product, the central processing unit 19 sends an operation signal to the device removal device 22 that is activated when the defective integrated circuit device 11 is supplied to the device removal device 22. As a result, the defective integrated circuit element 11 is removed from the element removal device 22.
, the device removing device 22 removes the uncut ground terminal pieces 4 and 5 of the integrated circuit device 11 from the strip 1.
The integrated circuit element 11 is removed from the strip 1 by cutting. Therefore, only good products among the large number of integrated circuit elements 11 are left on the strip 1, so by winding the band 1 into a hoop shape, a large number of integrated circuit elements 11 are left on the strip 1.
can be easily managed. In the figure, reference numeral 18 denotes feed holes formed at equal pitches in the longitudinal direction of the strip 1.

By supplying the hoop material with integrated circuit elements formed by this method to the electronic component supply apparatus, the integrated circuit elements are sequentially supplied to the electronic component supply apparatus in a predetermined posture. There is no need for any equipment to do this.

In the embodiments described above, the ground terminals 4 and 5 are integrally provided on the strip 1 without being cut, but the present invention is not necessarily limited to this. For example, an idle terminal used only for stably supporting the printed circuit board may be provided on the integrated circuit element, and the idle terminal may be provided integrally with the strip 1 instead of being cut into the ground terminals 4 and 5. It's okay.

In addition, in the examples described above, the manufacturing method of the present invention is described as “
An example was shown in which it was applied to the manufacture of a hoop material with an integrated circuit element in which a group of terminal strips were connected only on the negative side, but it was applied to the manufacturing of a hoop material for an integrated circuit device with a group of terminal strips connected on both sides. ”
Of course, the manufacturing method of the present invention may be applied to.

(Effects of the Invention) As explained above, the present invention provides a method in which a predetermined number of terminal strip groups are integrally formed at equal pitches in the longitudinal direction, and an integrated circuit element is integrally formed in each of the terminal strip groups.
