Description

[Detailed description of the invention] (a) Technical field of the invention This invention relates to a positioning mechanism for inserting a plastic lead-backed chip carrier (hereinafter referred to as PLCC) into a test socket.

PLCC is an LSI whose external form has been changed from the conventional pin insertion type to a surface-mounted package for high-density mounting, and has a structure in which leads are pulled out from all sides of the package.

(b) Purpose of the invention PLCC has many leads with a width of 0.4 mm.
When testing a PLCC, the PLCC must be positioned so that it makes accurate contact with the contacts of the test socket.

This invention provides a component positioning mechanism that transports and inserts a PLCC into a testing socket and accurately brings the PLCC into contact with the contacts of the socket.

(c) Example of the invention First, a configuration diagram of an example of this invention is shown in Fig. 1. In Figure 1, 1 is the rail, 2 is the stopper,
3 is a socket, 4 is a component, and 5 and 6 are guides.

The rail 1 is made, for example, an inclined surface so that the component 4 can move on the rail 1.

The stopper 2 is for the purpose of stopping the component 4 moving on the rail 1 at the position of the socket 3.

Use guide 5 and guide 6 to route part 4 to rail 1.
Form on top. The guides 5 and 6 can be moved in the direction of the arrow in FIG. 1 by a drive mechanism (not shown), and the width of the passage formed by the guides 5 and 6 can be changed.

The guide 5 has a stepped portion 5A, and the stepped portion 5A is configured to make surface contact with the side surface 3A of the socket 3. Similarly, the guide 6 has a stepped portion 6A, and the stepped portion 6A is configured to make surface contact with the side surface 3B of the socket 3.

The side surface 3B is the side surface opposite to the side surface 3A, and when the stepped portion 5A of the guide 5 is brought into surface contact with the side surface 3A of the socket 3, and the stepped portion 6A of the guide 6 is brought into surface contact with the side surface 3B of the socket 3, the guide Both side surfaces of the component 4 are sandwiched between the end 5B of the guide 5 and the end 6B of the guide 6, and the component 4 is configured so that the orientation of the component 4 between the guide 5 and the guide 6 matches the orientation of the socket 3.

Next, the plan view of FIG. 1 is shown in FIG. 2.

FIG. 2 shows a state in which the guides 5 and 6 are moved in the direction of the arrow in FIG. 2 until they hit the stoppers 7A to 7D, and the path formed by the guides 5 and 6 is widened.

In the state shown in FIG. 2, the component 4 can freely move on the rail 1.

Next, FIG. 3 shows a side view of the guide 5 and guide 6 brought close to each other.

In FIG. 3, the stepped portion 5A of the guide 5 is connected to the socket 3.
The stepped portion 6A of the guide 6 is in surface contact with the side surface 3B of the socket 3.

Next, a plan view of FIG. 3 is shown in FIG. 4.

As is clear from FIG. 4, part 4 is the guide 5.
The direction is forcibly corrected by the end 5B of the guide 6 and the end 6B of the guide 6, and when the part 4 hits the stopper 2 as shown in FIG. 4, the position of the part 4 is exactly above the socket 3. is set and parts 4 are placed in socket 3.
can be inserted into.

As shown in FIGS. 1 to 4, this invention controls the movement of the guides 5 and 6 in the direction of the arrow, and creates a passage that allows the part 4 to pass through easily until it hits the stopper 2. 4 is stopper 2
When it hits, the step 5A of the guide 5 hits the side surface 3A of the socket 3, and the step 6A of the guide 6 hits the side surface 3B of the socket 3, forcing the orientation of the component 4 between the ends 5B and 6B. This modification allows the component 4 to be inserted into the socket 3.

Component 4 is a PLCC, and component 4 is tested by inserting component 4 into socket 3 and bringing the contacts of socket 3 into contact with the leads of component 4.

(d) Effects of the invention According to this invention, the orientation and position of the component 4 are determined by applying the stepped portions 5A and 6A to the side surfaces 3A and 3B of the socket 3, so that the component 4 can be accurately placed in the socket 3. can be inserted into.
