Abstract

PURPOSE:To make a substrate common, reduce a manufacturing period of it, make it commonly usable by modification, and reduce a manufacturing cost of it by using components in common by a method wherein the substrate is formed into such a structure that a packaging section and electrodes of a common signal input wiring section are separated from each other. CONSTITUTION:An electrode 11 of a common signal input wiring section, an electrode 10 of a socket section, a signal input wiring 20, a jumper wire which connects the electrode 11 with the signal input wiring 20, and a packaging socket section 40 are provided onto a board. When the board is practically used, a shot-circuit wiring S, a capacitor C, and a resistor R are optionally connected between the electrode 10 of the socket section and the electrode 11 of the common signal input wiring section, so that the board can be adapted to many products if these components are re-connected for each product.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a board used when inputting signals to a number of products at the same time, such as a burn-in board for an IC.

[Conventional technology]

Figure 3 is a diagram showing an example of the use of a conventional board, where QO is the electrode for the lead of the mounting socket, Z is the signal input line for the input signal, and ■ is the jumper wiring that connects the electrode αO and the signal line. , ■ is the mounting socket part.

Signals 81 to 514 are applied to each product inserted into the mounting socket (2) through the signal input line (2), so that the products can be operated simultaneously.

[Problem to be solved by the invention]

With conventional boards, the mounting sockets and signal input lines are wired categorically for each product, so a board must be manufactured for each product, making it impossible to cope with sudden changes in demand for boards. In addition, when manufacturing the board, components such as mounting sockets must be purchased for each product, which increases the cost of manufacturing the board.

This invention was made to solve the above-mentioned problems, and aims to provide a board structure that can easily cope with fluctuations in board demand for products that use a common mounting socket, and that can reduce board production costs. shall be.

[Means to solve the problem]

The substrate according to the present invention separates the electrode of the mounting socket portion from the electrode connecting the wiring for common signal input.

[Effect]

The separated electrode structure of the present invention can be used freely to be short-circuited, disconnected, or inserted with parts depending on the purpose of use.

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

FIG. 1 is a diagram showing an embodiment of the present invention, and in the figure,
0υ is the electrode of the common signal input wiring part, QO is the electrode of the socket part, (1) is the signal input wiring, ■ is the jumper wire that connects the electrode αυ and the signal input wiring (E), - is the mounting socket part .

FIG. 2 is a diagram showing an example in which a board having the structure shown in FIG. 1 is actually used. In the figure, (S) indicates a short-circuit wiring, (R) a resistor, and (C) a capacitance.

As shown in Fig. 2, between the socket electrode Ql) and the input signal electrode east, there is a short-circuit wiring S, a capacitor C2, a resistor R
Since connections can be made arbitrarily, the board with the structure shown in Figure 1 can be applied to a large number of products by reconnecting each product.

In the above embodiment, the number of socket parts and the number of common parts may not be the same in the drawings. Further, the layout of the common signal input wiring may be on the same surface of the substrate, on the back surface, or in an intermediate layer of the substrate.

Further, the socket portion and a part of the common signal input wiring may be directly connected.

〔Effect of the invention〕

As described above, according to the present invention, the board structure is such that the electrodes of the mounting part and the common signal input wiring part are separated, so that the board can be used in common, which shortens the construction period of the board, allows for common use through modification, and allows parts to be used interchangeably. Sharing has the effect of reducing board production costs.
