Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes a socket (hereinafter referred to as 11: socket) L that fully supports an integrated circuit device (hereinafter 1., and nQ-d), and features the above-mentioned 1. 01, e, i Printed board, etc. (one of the means for mounting is a printed board, etc. (C, 1, C, socket all soldered) .

Part 1. c, How to insert into socket (C1, C, below 1.(,:.

Conventionally, the socket mounting method (referred to as the socket mounting method) has been widely used. Special rc1. c. Yozogoku delinquent 1. C. High temperature bias screening for the purpose of total removal, i, t,:.

In the high temperature operation pre-bending test, which is one of the reliability tests, +rJ, 1. above. C. Socket dressing method is commonly used. Also, for circuit reasons, 1. There are many cases in which the external connection terminal of C. and the power supply circuit or the ground circuit are connected by a 4-resistance element, and since then, the previous Re1. A resistor element that connects the external terminal of U, and the power supply circuit (hereinafter referred to as a pull-up resistor element), or a resistor element that connects the external terminal of Il, C, and the ground circuit (hereinafter referred to as a pull-down resistor). Motoko and Ki T
) μ was attached to the printed board. Especially in high-temperature bias screening, high-temperature operation life test, etc., pull-up resistor element or pull-down resistor element sound 1. (,
: Several to tens of pieces are used per piece, which increases the number of rcix circuits, and the number of parts increases, which reduces the reliability of the printed board and vice versa. (Production costs had to rise.

The object of the present invention is to eliminate the above-mentioned drawbacks (7. 1. L: which contributes to the mounting density of the printed circuit board and the same reliability).

The purpose is to serve the socket.

The feature of the present invention is that it is a resistor element that can be used as a pull-up resistor element or an RTX pull-down resistor element.
．． C, socket rc built-in resistor element and 1. e. Integrating the socket (C) The present invention will be described in detail using an embodiment.

Figure 1 shows the conventional 1. C. Socket external view 11/11
FIG. 2 is an electrical circuit diagram of FIG. 1. In Figure 1, the printed board mounting terminals i, e, insertion ports 1a, 2a, . . . , 6a, b, 2b, . It is expressed as shown in the rJ,m2 diagram.

FIG. 3 is an example of an external view of a socket with a resistive element according to a ninth embodiment of the present invention, and is an electrical circuit diagram of FIGS. In FIG. 3, the conventional 1. e. Fig. 1 is a sketch of the socket, and the only external feature is the printed board mounting end f7b (31), but there are six resistance elements IL1゜R2, ...R6(
(toKΩ for each resistance value)? One terminal of each resistor element Rt, l12) has one terminal of 1. C, is connected to insertion ports 1a, 2a and 3a, and other terminals a
It is connected to the printed board mounting terminal 8b through the terminal. Resistance element Jt4. The same goes for R5 and R6 [one terminal μ1. C
, Insertion ports 4a and 5a are connected to 6arn, and are connected to other terminals together with printed board mounting terminal 7b. ○ Resistor bare hand socket i printed board v due to non-embodiment.
'c When implementing conventional 1. e. Compared to the case where the socket is mounted on a printed board, the mounting capacity increases by two terminals, but the area for mounting one pull-down resistor or pull-down resistor becomes unnecessary, and the mounting density of the printed board remains the same. Furthermore, since there is no need to solder the pull-up resistor or pull-down resistor to the gold printed plate, the reliability is improved and the manufacturing cost of the glint plate is reduced.

In this embodiment, there are 6 terminals, 1. C. This is an example of a socket.

For example, multiple terminals such as 40 terminals ♀1. (In the case of sockets, the effect of the present invention is more pronounced.)
