Abstract

PURPOSE:To facilitate work with tweezers to fit an element-mounted pedestal into the groove of a fixation jig by making second grooves in the side walls of the first groove of the fixation jig to fit the element-mounted pedestal. CONSTITUTION:A fixation jig 42 to fix an element-mounted pedestal is for example a 2cm X 2cm X approx. 1cm gold-plated copper plate. A first groove 41 to fix the pedestal to the fixation jig 42 is made therein and semicylindrical second grooves 41 are made in the side walls of the groove 41 with a drill.

Description

[Detailed Description of the Invention] Industrial Application Field of the Invention An element for attaching a pedestal on which microscopic optical components such as lenses and elements such as optical semiconductor elements are mounted to measurement equipment such as optical measurement or electrical measurement. This relates to a mounting jig.

Conventional technology Conventionally, in order to attach a pedestal on which an optical semiconductor element is mounted to a measuring device, it is necessary to use the arrangement shown in Figs. 4 to 6, for example.
A mounting jig 42 with a rectangular groove 41 for mounting the pedestal 52! ,−
Figure 4 shows a perspective view of a holder with several mounting jigs. 41 is a rectangular groove in which the pedestal is mounted, and 42 (a mounting jig with a friend groove 41) be.

The attachment jig 42 is attached to the heat sink 43 and serves as a terminal for the electrode 45. The other electrode is needle 4
4, and is pressed by a fixing plate 46 of the needle 44 having a spring so that the needle 44 comes into contact with the electrode on the base when the entire holder is closed. In Fig. 4, it is equipped with eight mounting jigs 42 and a heat sink 43, which serves as a terminal for one electrode, is electrically separated from each other so that a large number of optical semiconductor devices can be measured instantly. How much force does such a holder require with normal measuring equipment?
It is installed in a predetermined location of the device and under computer control, a large number of optical measurements, electrical measurements, etc. are performed instantly. , is a perspective view of a pedestal on which an optical semiconductor element is mounted.

In FIG. 5(b), 55 is a semiconductor laser f, 53 is a ball lens installed to condense the light of the semiconductor laser, 5
4 is a heat sink. The electrode 57 should be installed to avoid applying pressure from the needle 44 of the holder to the semiconductor laser 55. electrode 57
Figure 6 shows how the pedestal 52 is fitted into the groove 41 with a pin set. The groove 41 is cut straight and vertically according to the size of the pedestal 52 so that the pedestal 52 is fixed.

Problems to be Solved by the Invention However, with conventional device mounting jigs (the upper grooves are carved vertically in a straight line to match the pedestal, there is not enough space for the bin set operation when fitting the pedestal into the groove). Because there is no such thing, in order to install the pedestal in the groove, it takes a lot of time and requires careful tweezers operation, such as sandwiching only the top of the pedestal with a pin set, aligning the bottom of the pedestal with the groove, and opening the pin set. In view of the above-mentioned problems, it is an object of the present invention to provide an element mounting jig that facilitates the tweezers operation of inserting the pedestal on which the element is mounted into the groove of the mounting jig. Means for Solving the Problems The present invention solves the above-mentioned problems.8 The present invention has a structure in which a second groove is carved in the side surface of the first groove of the mounting jig into which the pedestal on which the element is mounted is inserted. According to the present invention, a second groove is carved between the side surfaces of the first groove of the mounting jig into which the pedestal on which the element is mounted is inserted, and the tip of the bottle set holding the pedestal is inserted into the second groove. Accordingly, opening the bottle set in the space of the second groove facilitates the ÷cross operation of fitting the pedestal into the first groove.

Embodiment (Example 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIG. Pedestal C on which elements are mounted in the first embodiment
t It has a structure as shown in Fig. 5(b), and the pedestal 52 has minute dimensions of 4 mm x 4 I[1[1] and a thickness of about 1 mm. It is a mounting jig for fixing the pedestal 52, and is 2 cm x 2 cm in size and has a thickness of C, which is easy to operate.
A gold-plated copper plate with a thickness of about 1.5 m in thickness is fixed to a larger heat sink using screws, etc., and multiple mounting jigs are fixed to the holder to attach it to the measuring device. 4
1 is a groove for fixing the pedestal 52 to the mounting jig 42, and is sized so that the pedestal 52 is just fitted into it. 11 is a second groove carved for operating the bottle set of the present invention. In this embodiment, the pedestal 52 can be easily fitted into the groove 41 by opening the tip of the bottle set with the pedestal 52 sandwiched in the second groove 11. (Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIG. , except that the shape of the second groove is different (
Yo, they have the same configuration. The base 52 can be opened by inserting the tip of the bottle set into the wide second groove 21, and the base can be easily fitted into the groove 41 (Example 3) The third embodiment of the present invention and its manufacturing method will be described below with reference to the third embodiment.In FIG. 3(C), 41 is a groove for fixing the base 52,
The pig 32 is the third wide groove. When machining a square groove with a milling machine (the shape of the milling machine blade remains on the corner of the corner, it is difficult to obtain a sharp corner, so it is difficult to create a rounded corner.) The only processing that can be performed is to carve a corner into a columnar shape centered on a point (-the third embodiment of the present invention). This embodiment has both the cylindrical second groove of the first embodiment and the wide second groove of the second embodiment, making the tweezers operation easier. Groove 41 as shown in steps (a) and (b)
At the same time, carve the cylindrical corner groove 33 that must be carved when machining the pedestal so that it matches the pedestal, and at the same time carve the second groove 31 as shown in Figure 3 (a). groove 41
If the wide third groove 32 shown in Fig. 3 is carved, the groove machining can be performed efficiently.

Effects of the Invention As is clear from the above explanation, the present invention! The pedestal equipped with the melon element can be easily installed, reducing the time required to operate the bin set to less than half of the conventional time.
Conventional tweezers have a few percent of cases of accidentally dropping the pedestal while operating them.
This allows the installation of such a pedestal to be made very efficient.
