Description

Telecommunication connects contact device

Technical field

The utility model relates to a kind of telecommunication and connects contact device, and is particularly a kind of for planting an integrated circuit component and by the structure of a kind of telecommunication connection contact device that is connected do telecommunication on a telecommunication contact site and the circuit board.

Background technology

For a long time, tradition is with integrated circuit potted element (Integrated Circuit Package; Being called for short ICPackage) mode that is installed on circuit board (Circuit Board or claim Main Board) has two kinds, and a kind of is the dead and mode that can not plug of directly weldering, and another kind is replaceable and pluggable mode.The composite set that this pluggable telecommunication connects contact device and circuit board is applicable to usually needs upgrading, upgrade integrated circuit component, or on the integrated circuit (IC) apparatus of higher unit price, when circuit board or one of them fault of integrated circuit component maybe need be upgraded, then another element still can keep the continuation use, and for example be used to the plant socket of central processing unit (CPU) (Central Processing Unit: be called for short CPU) and the composite set of circuit board are typical examples.

See also Fig. 1 and Fig. 2, be the visible composite set that typically can plug integrated circuit component and electric connector thereof and circuit board in the market.Traditionally, for double asking can plug and good electrically purpose of connecting, the general practice is on integrated circuit component 11 (IC Package) contact pin 111 (Pins) to be set, and has the electric connector 13 (Socket) of most jacks 131 (PinHoles) for this integrated circuit component 11 of planting in the last setting of circuit board 12 (Circuit Board or title Main Board).Known integrated circuit component 11 packaged types have lead frame (Lead Frame) and two kinds of tin nodule number group encapsulation (Ball Grid Array: be called for short BGA).In recent years, for pursuing high-effect (being high-cooling property) integrated circuit component, often use crystal covering type tin nodule number group encapsulation (Flip Chip BGA Packaging) with high pin number.Its basic composition element generally includes as shown in Figure 1: an integrated circuit (IC) chip 112 (IC Chin) is with on the side surface that covers crystal type and be installed on a substrate 113 (Substrate), substrate 113 opposite side surfaces then be provided with some tin balls 114 (Solders) its by the circuit design of substrate 113 and electrical couplings in chip 112, the non-start face of chip 112 opposite sides then is pasted with a heat dissipation element 115 (Heat Sink).Because contact pin 111 and non-rigid high object, damaged by distortion, and be not easy and tin ball 114 firm engagement, therefore, present technology is soldered to it tin ball 114 after all needing earlier most contact pins 111 to be fixed on the intermediate plate 116 (Interposer) again.

As for, for the contact pin 111 for aforementioned public integrated circuit component 11 is planted, and must take into account the function of choosing again, all public contact pin type electric connectors 13 include following member now: a socket 132 with most jacks 131 is welded on the circuit board 12, a sliding panel 133 covers on socket 132 end faces with mode device that can linear slippage and one pull stock 134 devices and carry out micro-slippage at socket 132 sides for driving this sliding panel 133.Be equipped with conductive clip gripping member 137 in each jack 131 of socket 132 and be formed with weld pad 135 in jack 131 bottoms, conductive clip gripping member 137 lower ends are extended jack 131 bottoms and are formed contact pin 1371 for the some through holes 121 that insert circuit board 12.Be provided with conductive layer 122 for electrically connecting with contact pin 1371 in the through hole 121 of circuit board 12, circuit board 12 upper surfaces are with tin ball screen 124 definition (Solder Mask Defined; Be called for short SMD) or also can with non-tin ball shielding definition (NSMD) this through hole 121 and on the position of contact mat 1221, and contact pin 1371 extremely is fixed on the circuit board 12 together with electric connector 13 welderings by scolder 123,125.Position corresponding to jack 131 on the sliding panel 133 also is provided with big slightly perforate (not shown), by press down this pull stock 134 make its with bar axle 136 serve as axle be rotated up to 132 one-tenth levels of socket, can make sliding panel 133 carry out micro-slippage and the contact pin 111 of integrated circuit component 11 is clamped in the jack 131.When desiring the integrated circuit component 11 of choosing, then needing changes and is pulled to and socket is spent angles for 132 one-tenths vertical 90 pulling stock 134, and contact pin 111 will be released and desirable from integrated circuit component 11 like this.

See also Fig. 3 and Fig. 4 and be another kind of public the plugged integrated circuit component and the composite set of electric connector and circuit board thereof, because the integrated circuit component 11 of this communal technique all is similar to the described known technology of above-mentioned Fig. 1 with the structure major part of electric connector 13a, thus will be not give unnecessary details its detailed element and structure and only with dashed lines represent the schematic diagram of its overall appearance composition.At the electric connector 13a shown in Figure 3 and the maximum difference of previous embodiment, the socket bottom that is this electric connector 13a is not to be the pin-like structure and to be to use some tin balls 138, and the lower end of the conductive clip gripping member 137a among the electric connector 13a directly bent 90 degree and, and on circuit board 12a, through hole is not set and tin ball pad 126 is set instead as the tin ball pad 139 that combines with tin ball 138.Carry out corresponding heat weldable technology (being commonly called as tin stove or Solder Reflow technology) by tin ball pad 126,138 fusions of tin ball and weldering extremely can be fixed between the two tin ball pads 139,126 12a on the tin ball 138 of electric connector 13a and the circuit board.The shortcoming of this communal technique is, the tin ball pad 139 that no matter is provided in a side of the conductive clip gripping member 137a lower end of electric connector 13a, the tin ball pad 126 that also is provided in a side of 12a on the circuit board, all be the structure on simple plane fully, so tin ball 138 and tin ball pad 139,126 only is the plane contact combination, not only the little electrical characteristic of contact area is relatively poor relatively, and in conjunction with structural strength also relatively poor relatively, may cause the situation that the product disqualification rate improves even tin ball 138 peels off, and in hot welding, might cause short circuit and electrically unstable phenomenon because of tin ball 138 flashes, simultaneously, the not good situation of coplanarity (Co-Planarity) after also often causing electric connector 13a and 12a on the circuit board combining.
