Abstract

PURPOSE:To obtain a universal burn-in board, by connecting an input pulse/ power source supply section to a socket for packaging ICs through an input/output pin switching section in such a manner as to make the connection changeable according to the type of IC. CONSTITUTION:Input pulse parts P1-P13 of an input pulse/power source supply section J0 are short-circuited to terminals 1, 2, 4, 5, 9, 10, 12 and 13 by inserting mini jumpers M for short-circuiting each comprising two pipes C and D coupled electrically into rapping pins A and B located at the respective positions. The power source Vcc and the GND are short-circuited to terminals 14 and 7 respectively with the mini jumpers M by the same means. At input/output pin changeover sections J11-Jnm, likewise, an input pin, a power source pin and a GND pin are short-circuited with the mini jumpers M and output pins 3, 6, 8 and 11 are opened to prevent collision between samples.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a burn-in board for mounting ICs, and particularly to a universal burn-in board capable of mounting a wide variety of IC's.

[Technical Background and Problems of the Invention] Dynamic burn-in, in which electronic elements are subjected to a high level of screeching before use in order to stabilize characteristics and reveal defects in order to eliminate initial defects in ICs, has the advantage of having a high screeching effect. It has been widely implemented. However, it is necessary to switch the pulse supplied to the input e and the output pin in response to changes in the product depending on the type of pin connection of the hXL I C.
In the worst case, it had the disadvantage of requiring one dedicated burn-in board for each type. Therefore, this is not a particular problem for IC manufacturers who handle large quantities of one type of IC, but for IC users who handle one type of IC in small quantities, a large amount of equipment costs are required, which has been an obstacle when implementing burn-in.

['R Moe's Purpose The present invention has been made in view of the above-mentioned points, and its purpose is to produce I of the same shape with one burn-in board.
The purpose of this invention is to provide a universal burn-in-bow bottom that can handle various varieties of C.

[Summary of the Invention 1 The present invention connects an input pulse and power supply section to a socket for IC mounting via an input/output pin switching section, so that the connection can be changed depending on the type of the IC. This is how the above object is achieved.

[Embodiment of the Invention] An embodiment of the burn-in board according to the present invention will be described below with reference to the drawings.

An embodiment of the present invention is shown in FIG. 1 and FIG. 2. In FIG. 1, Jo is an input pulse and power supply section, and terminals 1 and 2 correspond to external input pulse sections P1.about.P1≧.

and the corresponding input/output pin switching sections -In to 14 are connected to pins 1 to 14 by wrapping wiring or the like.

As described above, according to this embodiment, the connections between the input pulse and power supply section Jo and the input/output pin switching section Jll--Nya can be changed by attaching and detaching the mini-jumper M to the wrapping pins A and B. Can be used as a burn-in board.

1.0, all types of ICs can be handled with one burn-in board if they have the same shape, ie, the number of pins, etc. Therefore, the number of burn-in boards to be prepared when performing dynamic burn-in is reduced, burn-in can be performed easily, and it is expected that the quality of the IC used will be improved.

In the above embodiment, the case where the number of pins of the IC is 14 was explained, but this number is 17! It is not limited to I pins. In addition, we have explained the case where the mini jumper is short m2, but when the load is required from IC type 1, 41 Fig. 3 - As shown in 2-wood pipe C,
A load mini-jumper N may be used in which a resistor R is provided to the wire A7 that connects the wire D. Furthermore, although dynamic burn-in has been described above, "C" can also be applied as a universal board for static burn-in, commonly known as aging.

[Effects of the Invention] As described above, according to the present invention, the burn-in board is provided with an input/output pin switching section, and the connection between the IC and the input pulse and power supply section can be changed using a mini jumper. Same shape I with one burn-in board
Now we can handle all varieties of C.
Since burn-in can now be carried out easily, the effect is great.
