Abstract

The utility model provides a stack type socket, which can be used on the BIOS of a motherboard. The stack type socket mainly comprises a lower socket and an upper socket, a chip select pin of the lower socket and a ground connecting pin are connected electrically; the upper socket is fixed on the lower socket, a chip select pin of the upper socket and a main power supply pin are connected electrically, in addition, the upper socket corresponds with other pins of the lower socket one to one and is connected with other pins of the lower socket electronically except the chip select pin, the ground connecting pin and the main power supply pin, and the upper socket and the lower socket are sealed with PLCC. The stack type socket of the utility model utilizes the BIOS in the upper socket of the stack type socket to replace the BIOS of the motherboard for verifying the codes, thus flash storage damages are reduced, and the time for debugging can be reduced.

Description

The stacking-type socket

Technical field

The utility model relates to a kind of socket, relates in particular to a kind of stacking-type socket.

Background technology

Although technology is constantly ripe, in test process, the problem that mistake hardware and programming code can't be carried out often causes mainboard to start shooting, this just need restart BIOS or more fresh code with testing host, until the code that rights a wrong.Thus, will cause the rate of decay of BIOS to be quickened, thereby cause relevant issues, and the transportation of delay product.

And in test process, also can analyze sometimes to being that BIOS is bad by mistake and cause system's guiding failure, and when changing BIOS, damage mainboard easily.

Summary of the invention

In view of the above problems, the utility model provides a kind of stacking-type socket.

In order to achieve the above object, the utility model has adopted following technical scheme: a kind of stacking-type socket, and it is applied on the BIOS of mainboard, and described stacking-type socket mainly comprises lower floor's socket, and the chip select pin of this lower floor's socket and grounding leg electrically connect; An and upper strata socket, it is fixed on this lower floor's socket, a this upper strata socket and a BIOS chip electrically connect, and the chip select pin of this upper strata socket electrically connects with main power supply pin, in addition, this upper strata socket and other pin one by one corresponding and electric connection of this lower floor's socket except that chip select pin, grounding leg, main power supply pin, so, the BIOS of this upper strata socket is activated, and has replaced the BIOS on the mainboard.

Preferable, the utility model provides a kind of stacking-type socket, and wherein, the chip select pin of described upper strata socket and lower floor's socket is the 24th pin; The grounding leg of described upper strata socket and lower floor's socket is the 16th, 26,28 pin; The main power supply pin of described upper strata socket and lower floor's socket is the 25th, 27,32 pin.

Preferable, the utility model provides a kind of stacking-type socket, and wherein, described upper strata socket and lower floor's socket are the PLCC encapsulation.

Compared to prior art, stacking-type socket described in the utility model utilizes BIOS in the upper strata socket of stacking-type socket to replace the BIOS of mainboard in test process, to examine code, has reduced the damage of flash memory, has saved the time of debugging.

Embodiment

Please refer to Figure 1 and Figure 2.Stacking-type socket described in the utility model, it mainly is applicable in the test process of HW/SW.In present embodiment, described stacking-type socket applications is in an electronic installation, and this electronic installation is a computer.And this stacking-type socket mainly comprises a upper strata socket and lower floor's socket, and this upper strata socket and this lower floor's socket are the PLCC encapsulation.

The BIOS chip of described upper strata socket and the good content of a burning electrically connects, and the fool proof angle under excision upper strata socket and the lower floor's socket base plate, with the yellow glue of solid it is cemented, to make stacking-type socket described in the utility model.

Wherein, the chip select pin (INIT#) of this upper strata socket and lower floor's socket is the 24th pin, and main power supply pin (VCC) is the 25th, 27 and 32 pin, and grounding leg (GND) is the 16th, 26 and 28 pin, and above-mentioned chip select pin is that high level is effective, and BIOS started working when promptly this chip select pin was high level.

Please refer to shown in Figure 1ly, be the fundamental diagram of upper strata socket.As shown in the figure, the chip select pin of upper strata socket and the corresponding welding of main power supply pin.

Please refer to shown in Figure 2ly again, be the fundamental diagram of lower floor's socket.As shown in the figure, the corresponding connection of the chip select pin of lower floor's socket with grounding leg.

In addition, the corresponding one by one and welding of other pin except that chip select pin, grounding leg, main power supply pin with this upper strata socket and this lower floor's socket.

The BIOS that the lower floor socket of this stacking-type socket is embedded aforementioned calculation machine mainboard goes up and starts computer, because the corresponding connection with grounding leg of chip select pin of lower floor's socket, then the chip select pin of this lower floor's socket is always low level, so, the BIOS conductively-closed on this mainboard; And because the chip select pin of upper strata socket and the corresponding welding of main power supply pin, then this chip select pin is always high level, and this upper strata socket and this lower floor's socket corresponding one by one and welding of other pin except that chip select pin, grounding leg, main power supply pin, then the BIOS on this upper strata socket is activated, therefore, the BIOS on the alternative original mainboard of the BIOS on this upper strata socket carries out system's guiding to computer.
