Description

The circuit board combination

[technical field]

The utility model is about a kind of circuit board combination, refers in particular to a kind of circuit board and is provided with terminal, and chip module directly compresses the circuit board combination of contact terminal.

[background technology]

Utilizing electric connector fixed chip module and connecting on printed circuit board (PCB) is the technology that the industry is familiar with.The prior art electric connector comprises pedestal, cover plate up and down, terminal, and rocking bar.Wherein pedestal is provided with the plurality of terminals hole that is arranged, and upper cover plate and rocking bar are hubbed at the lower cover both sides, and upper cover plate is pushed down chip module by the compacting of rocking bar, and chip module is connected with conducting terminal.Prior art needs an insulating body to accommodate terminal, need rocking bar to fix upper cover plate simultaneously, therefore, in manufacture process,, use rocking bar fixing owing to suppress bad or operate miss causes terminal impaired because the too much use of material has caused unnecessary waste.

In addition, the variation of the whole configuration of electric connector directly affects the variation of size, along with the CPU technical field continuous development and renewal, more and more obvious to the trend of micro-scale technology field development.Therefore require connector between CPU and circuit board to more microminiaturized development, certainly will require electric connector on whole configuration with bigger improvement and renewal were arranged in the past.

In addition, reducing and can causing the difficulty of making and assembling of electric connector size also can produce the high problem of manufacturability difference and fraction defective, therefore will cause lower reliability and economy.This low reliability also can cause bad influence to system combination and motherboard factories when being installed on electric connector on the circuit board.

Therefore, be necessary to provide a kind of circuit board combination structure that can overcome above problem and can effectively improve economic technology and improve quality and be easy to produce.

[utility model content]

The purpose of this utility model provides a kind of circuit board combination structure of saving material, to improve business efficiency.

For achieving the above object, this circuit board combination comprises circuit board and the chip module that is mounted thereon, and this circuit board combination comprises that also a location structure is with locating circuit board and chip module.

Compared with prior art, the utility model circuit board combination need not used electric connector, thereby can save material, reduces cost, and in addition, this utility model also comprises a location structure, thereby guarantees that excellent electrical property is connected between chip module and the circuit board.

[embodiment]

Cooperation further specifies to the utility model circuit board group below in conjunction with the drawings and specific embodiments.

See also Fig. 1 to shown in Figure 3, the combination of the utility model circuit board, it comprises circuit board 1 and the chip module 2 that is mounted thereon.On chip module 2, be provided with radiator 3 in addition, this radiator 3 comprises and chip module substrate contacted 30 and the radiating fin 31 that is positioned on the pedestal, can this radiator be matched with backboard 32, chip module is fixed on the circuit board 1, and can be the chip module heat radiation.

Circuit board 1 is provided with the conducting terminal 10 that can directly compress contact for chip module, conducting terminal 10 is installed on the circuit board 1, it comprises and protrudes in the contact site 100 of circuit board 1 surface contact with chip module 2 compression, and this contact site 100 is to be arranged on the circuit board 1 towards opposite two groups.Around conducting terminal 10, respectively be provided with a location hole 11 that is used for fixing chip module 2 in addition.

Chip module 2 mid portions slightly protrude in the marginal portion, respectively be provided with and location hole 11 corresponding reference columns 20 around its lower end, reference column 20 comprises that the horizontal location portion 200 that inserts location hole on the circuit board 1 is (certain with the vertical location division 201 that is attached thereto and can be connected on the circuit board 1, described horizontal location portion and vertical location division also can lay respectively at the diverse location of chip module, and not necessarily be positioned at simultaneously on the reference column, or also can be horizontal location portion or vertical location division are only arranged.), reference column 20 is corresponding one by one with location hole on the circuit board 1, and both cooperations can be positioned on the circuit board 1 chip module 2 exactly, and are fixing for radiator 3.The vertical location division 201 of reference column is provided with suitable height, make chip module 2 with process that conducting terminal 10 contacts in effective protection terminal, it is impaired that terminal is difficult for.Above-mentioned reference column 20 and location hole 11 be common to constitute location structures, is used for the positioning chip module, realizes that chip module contacts with the conducting terminal excellent electrical property.

See also shown in Figure 4ly, be second embodiment of the present utility model, itself and the foregoing description difference are that its location hole is positioned on the chip module, and correspondingly, its reference column is positioned on the circuit board, also can reach the effect of accurate location.See also Fig. 5 to shown in Figure 7, be the 3rd embodiment of the present utility model, itself and the foregoing description difference are, location hole or reference column are not set on the chip module, but on circuit board 1 conducting terminal 10 around respectively be provided with an insulator 12, this insulator 12 comprises body 120 and the reference column 121 that is extended by body downwards, in order to the guide vane end stop 122 of butt chip module 2.Reference column 121 matches with location hole 11 on the circuit board, but guide vane end stop 122 butt chip modules 2, chip module 2 outer rims near body 120 inboards to realize the effect of location.And the height A of guide vane end stop is a little less than the terminal height B, make chip module 2 with process that conducting terminal 10 contacts in effective protection terminal, it is impaired that terminal is difficult for.
