Description

Transplantable microcomputer chip plate

Technical field

The utility model relates to a kind of microcomputer chip plate, relates in particular to a kind of microcomputer chip plate that easily is connected to plug with the micro computer mainboard.

Background technology

Progress along with the microcomputer chip production technology, it encapsulates more and more miniaturization, generally all be QFP, LQFP, encapsulated types such as TQFP, volume and cost all have reduction than the DIP encapsulation, but, in a single day these IC are welded on the mainboard, just are difficult to dismounting, in case the program burn writing mistake, perhaps program need be changed, then can only carry out programming, perhaps simply change IC or mainboard, will certainly increase like this to return and be bundled into this by jtag port default on the mainboard, and the mainboard of going out for sale, then can't carry out field modification program or change chip during the discovery procedure mistake, can only change mainboard and just can deal with problems, maintenance cost increases.

If the chip of DIP encapsulation then also can use the IC seat to solve, though for the chip of SMD encapsulation the IC seat is arranged also, but its price is very high and unreliable, therefore, uses that it must return bag to production, after-sales service has brought difficulty.

We know, the port of each chip all has definition and function separately, when the chip place in circuit, in order to make this chip operate as normal better, all will be according to the definition and the function of each port, necessary some resistance or electric capacity or crystal oscillator or other elements of inserting, we claim that at this these elements are the subsidiary component of chip.

The utility model content

Technical problem to be solved in the utility model provides a kind of microcomputer chip plate, its can be easily plug ground connect the micro computer mainboard supporting with it, the programming program is carried out to chip in the scene of realizing, and portable, easy replacing, easy recycling.

For solving the problems of the technologies described above, the utility model provides following technical scheme:

A kind of transplantable microcomputer chip plate, comprise chip that contains the paster encapsulation type and the subsidiary component that is connected with described chip, described microcomputer chip plate also comprises the printed circuit board (PCB) that is used to install described chip and described subsidiary component, is contained at least one socket that is connected with the port of described chip on the described printed circuit board (PCB), and socket is provided with the socket that combines with row's pin of mainboard.

By above scheme as seen, the transplantable microcomputer chip plate that the utility model provides is connected with row's pin on the micro computer mainboard by socket, wrong or when needing upgrading when the program of microcomputer chip, can pull up the microcomputer chip plate easily, by the programming program port of chip, chip is carried out on-the-spot programming program or changes the microcomputer chip plate; Realize being equipped with the easy plug of the microcomputer chip plate of paster encapsulation type chip, portable, easy replacing, easily recycling, reduced production, maintenance cost.

A kind of preferred version of the present utility model is, the wherein socket on the printed circuit board (PCB) tightly is with an outer framework, and described outer framework is identical with the profile of this socket, and the edge thickness of outer framework is greater than the distance between two adjacent row's pins on the mainboard.By this scheme as can be known, can prevent that the part on the mainboard from arranging the outer of cushion to socket, thereby the row's of making pin is connected correctly with corresponding socket.

Fig. 3 is the part synoptic diagram of relevant micro computer mainboard of the present utility model;

Fig. 4 is a kind of structural representation of outer framework of the present utility model.

Embodiment

As depicted in figs. 1 and 2, the utility model comprises chip 1, subsidiary component 2, outer framework 3, first socket 41, second socket 42, printed circuit board (PCB) 5.The one side that chip 1 wherein is housed on the printed circuit board (PCB) 5 is for positive, and the one side opposing with the front is reverse side; First socket 41 and second socket 42 are provided with socket 8.

The utility model has its micro computer mainboard 6 that is suitable for, and the row-

needle receptacle

71,72 with first socket 41, the 42 corresponding combinations of second socket is set on (in conjunction with Fig. 3) this micro computer mainboard 6, and the row's pin 73 on the row-

needle receptacle

71,72 is corresponding one by one with the port of chip 1.

Concrete structure of the present utility model is as follows: a printed circuit board is equipped with chip 1 on 5 fronts, its reverse side parallel alignment ground is provided with first socket 41 that is connected with some ports of chip 1, second socket 42 that is connected with other ports of chip 1, wherein, framework 3 outside on first socket 41, being provided with, outer framework 3 is identical with first socket, 41 profiles, (in conjunction with Fig. 4) outer framework 3 is the rectangular parallelepiped of hollow, outer framework 3 has two short edge 31 and two long frame edges 32, the thickness L of long frame edge 32 is greater than the distance R between two horizontal adjacent row's pins 73 on the mainboard, the thickness D of short edge 31 greater than on the mainboard between two vertical adjacent row's pins 73 apart from T, outer framework 3 and first socket, 41 wringing fits; According to the function of chip port, the subsidiary component 2 of chip 1 is properly installed on first socket 41, second socket 42 connects on some circuits of chip port.

When the utility model installs to described micro computer mainboard 6, because the thickness L of long frame edge 32 is greater than the distance R between two horizontal adjacent row's pins 73 on the mainboard, the thickness D of short edge 31 greater than on the mainboard between two vertical adjacent row's pins 73 apart from T, and first socket 41 and the 42 parallel alignment settings of second socket, the outer that can the row's of preventing pin 73 be inserted into first socket 41 and second socket 42, thus the row's of making pin 73 correctly with first socket 41, second socket 42 on socket 8 join.
