Description

[Detailed Description of the Invention] The present invention relates to the structure of a carrier on which a flat package containing a semiconductor element is mounted.

FIG. 1 shows a plan view of a conventional carrier, and FIG. 2 shows a sectional view of its main parts.

As shown in the figure, this carrier has a carrier frame 10 whose center part is punched out, and a plurality of band-shaped protrusions 11 are provided thereon, and furthermore, support arms 13 are provided at the ends of opposing inner sides 12, respectively.

Figure 3 is a plan view showing an example of a flat package.
is the main body, and 21 is an external terminal, which is provided horizontally with respect to the main body 20.

In order to mount such a flat package on the above-mentioned carrier, the two support arms 13 are spread outward, and the external terminals 21
is inserted into the groove 14 between the band-like convex portions 11, and the flat package main body 20 is held and supported using the elastic force of the tip of the support arm 13.

The support arm 13 is provided with a support claw 15 and a support shelf 16, which support the main body 20.

The state is shown in the main part sectional view of FIG.

By mounting the flat package on the carrier in this manner, the external terminals 21 are protected and the semiconductor element in the flat package can be easily attached to and detached from the test equipment when performing the final test.

Note that the three cut sections provided in the carrier frame 10 are for facilitating the positioning of the flat package during the above test.

Since the carrier described above uses the elastic force of the two support arms 13 to sandwich the flat package main body 20, the two support arms 13 must be spread apart using tweezers or the like when attaching or detaching the flat package.

However, the process is actually very complicated, which is one of the drawbacks of conventional carriers.

The present invention aims to eliminate the above-mentioned drawbacks and provide a carrier structure that allows flat packages to be easily attached to and detached from the carrier.

The purpose of this is to provide a plurality of strip-like protrusions in parallel on at least one side of a carrier frame with a punched center part, and to insert the external terminals of the flat package between them so that the flat package can be mounted thereon. and a flat package, wherein support arms are provided at the ends of two opposing inner sides of the carrier frame, and the main body of the flat package is sandwiched and supported by the elastic force of the tips of the two support arms. In the carrier, the support arm is provided with an attachment/detachment claw for expanding the support arm outward when the flat package is attached or detached so as to protrude from a punched portion of the carrier frame to the back side of the carrier frame. This is achieved by providing a flat package carrier featuring:

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 5 shows a plan view of the carrier of this embodiment, and FIG. 6 shows a sectional view of its main parts.

In this embodiment, as shown in the figure, a detachable claw 18 is provided for expanding the support arm 14 outward.

The attachment/detachment claw 18 has a half-moon-shaped shelf 19 as shown in FIG.

In this way, the attachment/detachment claw 18 protruding from the punched part of the carrier frame 10 to the back side of the carrier frame 10 is used to spread the support arm 13 outward, but the method is as follows:
For example, as shown in FIG. 7, the carrier is placed on two parallel rails 30, and the two rails 30 are inserted inside the attachment/detachment claw 18 as shown in the sectional view of the main part in FIG. By moving the carrier laterally along the rail 30 and moving the carrier onto the attachment/detachment section 31 where the rail 30 has partially expanded as shown in 31 in the figure, the support arm 13 can be moved in accordance with the expansion of the rail 30. Easily expanded.

In addition, since the attachment/detachment claw 18 has a structure having a half-moon-shaped shelf,
The rail 30 can be smoothly moved to the attachment/detachment part 31.

As described above, according to the present invention, the flat package can be attached to and detached from the carrier very easily.

Claims (1)

[Claim for Utility Model Registration] A plurality of strip-like protrusions are provided in parallel on at least one side of a carrier frame whose center is punched out, and external terminals of the flat package are inserted between them to mount the flat package. Support arms are provided at the ends of two opposing inner sides of the carrier frame, and the main body of the flat package is sandwiched and supported by the elastic force of the tips of the two support arms. In the carrier for a flat package, the support arm is provided with an attachment/detachment claw for expanding the support arm outwardly when attaching or detaching the flat package so as to protrude from a punched portion of the carrier frame to the back side of the carrier frame. A flat package carrier with the following features:
