Description
Technical field
The present invention relates to be arranged on the jockey that the IC encapsulation waits the projection electrode that is provided with on the electronic component, relate in particular to a kind of jockey that described projection electrode is suppressed the connecting portion of the elasticity wrist with three-dimensional shape and connect.
Background technology
Contact device with a plurality of spiral helicine contact shoes is disclosed in following patent documentation 1 and patent documentation 2.Bottom surface at electronic components such as IC encapsulation is provided with a plurality of spherical projection electrodes, and each projection electrode is suppressed to contact shoe, and projection electrode contacts respectively according to man-to-man relation with contact shoe.
In addition, patent documentation 1 described spiral helicine contact shoe is towards the outstanding three-dimensional shape of electronic component, when electronic component is set on the jockey, contact shoe is pressed and is out of shape in the mode of damaging by pressure to projection electrode, and the effect of contact shoe elastic recovering force is at this moment suppressed to described projection electrode down.
Patent documentation 1: 2005-No. 209419 communiques of TOHKEMY
Patent documentation 2: 2004-No. 234872 communiques of TOHKEMY
As described in patent documentation 1, following advantage when being three-dimensional shape, spiral helicine contact shoe is arranged, under the effect of the repulsive force when contact shoe damages by pressure, the elastic force pressure grow of contact shoe and projection electrode, the conduction of contact shoe and projection electrode improves.But, when spiral helicine contact shoe is three-dimensional shape, be easy to generate following problem.
Contact shoe is spiral helicine three-dimensional shape, and when contact shoe is spherical form etc., be pressed and when damaging by pressure, effect has repulsive force upwards for projection electrode at contact shoe, and be horizontal pressing force for the orientation that projection electrode also acts on oriented contact shoe.When horizontal pressing force acts on projection electrode, will stagger from the center of contact shoe in the center of projection electrode, and consequently contact shoe descends easily to the elastic force pressure of projection electrode.
Especially described spiral helicine contact shoe such as patent documentation 1 closely forms the elasticity wrist from coiling top to the coiling terminal, and the front end of elasticity wrist is positioned at the approximate centre of helical pattern.Therefore, when the projection electrode of spherical form etc. was crimped into this contact shoe, what direction is described horizontal elastic force etc. can become was indefinite, does not promptly have systematicness.Therefore, when all projection electrodes are crimped into contact shoe, unpredictable for electronic component can act on horizontal that towards the application of force, be difficult to form the situation that countermeasure reply dislocation masterpiece is used for electronic component.
In addition, when the center of all projection electrodes and when being crimped from the off(-)center of the spiral pattern of contact shoe, for all projection electrodes can act on make that its magnitude of misalignment increases towards power, contact shoe is died down to the crimp force of projection electrode.
Surface at projection electrode is formed with oxide-film or oil film mostly, when a little less than the contact force of described contact shoe and projection electrode, because described oxide-film or oil film make electrical contact resistance increase, has the anxiety that causes loose contact or inductance rising.
Summary of the invention
The present invention solves above-mentioned existing problem, and it is a kind of when projection electrode is contacted with the elasticity wrist of three-dimensional shape that purpose is to provide, and offsets the jockey to the cross force of all projection electrode effects easily.
In addition, another object of the present invention is to provide a kind of make from the connecting portion of three-dimensional shape act on projection electrode crimp force towards regularization, and offset regularization easily crimp force towards jockey.
Jockey of the present invention, its setting has the electronic component of a plurality of projection electrodes, it is characterized in that, a plurality of connecting portions that the plane earth configuration contacts with described projection electrode on the bearing-surface of described electronic component are being set, be provided with the elasticity wrist of conductivity at each connecting portion, described elasticity wrist leaves and extends from described bearing-surface, and to the crimp force of described projection electrode performance to the direction parallel with described bearing-surface, to described projection electrode apply identical towards a plurality of described connecting portion formation group of described crimp force, the group of the above described connecting portion of at least 3 groups is set, described crimp force towards different according to group, described crimp force be distributed as in the face parallel with described bearing-surface all directions of quadrature can offset towards.
When jockey of the present invention is crimped on each connecting portion at projection electrode, from the horizontal crimp force of the elasticity wrist direction that effect is predetermined to projection electrode of connecting portion.Then, act on an electronic component each projection electrode described crimp force towards being 3 directions at least, be set in all directions of the above crimp force quadrature on the face parallel that distributes of this 3 direction with described bearing-surface can offset towards.That is, described crimp force itself is towards all directions of quadrature, or the component towards the direction of described quadrature of described crimp force be cancel out each other towards.
Therefore, be difficult to act on dislocation power for the integral body of electronic component, the elasticity wrist of described connecting portion reliably suppresses in each projection electrode.Even consequently have oxide-film or oil film etc. on the surface of each projection electrode, utilize the elasticity wrist of powerful crimping to remove oxide-film or oil film easily, can make the good conducting of elasticity wrist and projection electrode.
For example, described elasticity wrist of the present invention forms helical form, and its front end is in the position of leaving from described bearing-surface.And then the present invention is preferably, the center of the helical trajectory of the elasticity wrist when overlooking described connecting portion, and the configuration of staggering of the front end of described elasticity wrist, this front end suppresses in described projection electrode, brings into play described crimp force.
As mentioned above, the front-end configuration of spiral helicine elasticity wrist is in from the position of the off(-)center of spiral pattern the time, spherical or when cutting out capable etc. the projection electrode of a circular cone and being crimped on this elasticity wrist, by the front end of described elasticity wrist, can act on equidirectional and horizontal crimp force all the time to projection electrode.So, can determine regularly from the elasticity wrist of a connecting portion put on projection electrode described crimp force towards, therefore, form group by connecting portion towards unanimity by the elasticity wrist, can from the connecting portion in this group to projection electrode apply identical towards crimp force.And then, by described group more than 3 groups being set, can eliminating the dislocation power that acts on electronic component, perhaps should dislocation power not be limited in and can bring the conducting of connecting portion and projection electrode in the dysgenic scope.
For example, the present invention preferably is provided with the group of 4 groups of described connecting portions, differs 90 degree mutually in each direction of organizing the described crimp force of performance.
In addition, the size of the described elasticity wrist of the connecting portion of the preferably all formation group of the present invention is all identical.At this moment, the quantity of the described connecting portion that contacts with the described projection electrode of described electronic component is equal number in each group.
But, in the present invention, also can be that the elasticity wrist that varies in size mixes.The crimp force that acts on projection electrode from the elasticity wrist that varies in size produces the poor of size.But, the summation of crimp force of equidirectional that acts on projection electrode from the connecting portion of each group is between each group more than 3 groups, can cancel out each other, as long as perhaps can roughly offset, the dislocation power that just can eliminate the electronic component effect maybe can reduce dislocation power, can make the elasticity wrist reliably be crimped on projection electrode.
In addition, the elasticity wrist at all connecting portions is identical shaped and is under the situation of same size that the quantity of connecting portion there is no need certain strict conformance in each group.Even the quantity difference of connecting portion of each group, by at each group with crimp force towards being set at the direction that can offset, just can not act on big dislocation power to electronic component, the elasticity wrist of connecting portion reliably can be crimped on projection electrode.
The present invention can according to the configuring area of each group zoning connecting portion, belong to phase connecting portion on the same group and can be positioned at identical zoning in described bearing-surface, and the connecting portion that belongs to each group also can mix configuration.
The invention effect
Jockey of the present invention when the projection electrode of electronic component is crimped on the elasticity wrist of a plurality of connecting portions of three-dimensional shape, can make the dislocation power that acts on electronic component offset, and consequently makes elasticity wrist and projection electrode conducting.
In addition, can determine from each elasticity wrist act on projection electrode crimp force towards, the pattern by making the elasticity wrist towards unanimity, act on from the connecting portion on the same group mutually projection electrode crimp force towards being set at equidirectional easily.Therefore, can at each the group with crimp force be set at cancel out each other towards.

Connecting portion 20A is a flat shape shown in Figure 5.The arrangement pitches of connecting portion 20A for example is below the 2mm, or below the 1mm.In addition, the maximum of the overall dimension of connecting portion 20A also is below the 2mm, or below the 1mm.
Connecting portion 20A is connected support 21A and forms with elasticity wrist 22A one.Elasticity wrist 22A forms spiral-shaped, and the coiling top of elasticity wrist is that base portion 23A and support 21A form one.The coiling terminal of elasticity wrist 22A is the central part that leading section 24A is positioned at spiral.
Described support 21A has the vertical edge 26A of portion of linearity extension and a pair of horizontal edge 27A of portion, the 27A that at right angles extends from the two ends of this vertical edge 26A of portion, and support 21A roughly is a rectangle.Spiral helicine elasticity wrist 22A roughly reeled for 2 weeks to leading section 24A from base portion 23A.Among the outermost outer peripheral edges 25A of spiral helicine elasticity wrist 22A, be 25A1 and 25A2 at the maximum at interval point of the direction parallel with the described vertical edge 26A of portion, among the described outer peripheral edges 25A of described horizontal stroke, point maximum at interval on the direction parallel with the described horizontal edge 27A of portion is 25A3,25A4.And the imaginary line parallel with the described vertical edge 26A of portion of point of contact 25A1 and some 25A2 is vertical datum line Oa, and point of contact 25A3 is horizontal datum line Ob with the imaginary line parallel with the described horizontal edge 27A of portion of some 25A4.
When if the intersection point of described vertical datum line Oa and horizontal datum line Ob is the center O 1 of spiral helicine elasticity wrist 22A, the leading section 24A of elasticity wrist 22A is in the position of leaving from described center O 1.In addition, when the intersection point of establishing the most inboard edge portion of elasticity wrist 22A and described horizontal datum line Ob is 28A1 and 28A2, do not have the part of elasticity wrist 22A between intersection point 28A1 and intersection point 28A2, this part is the space.In addition, the ratio of the distance between the distance in the space between described intersection point 28A1 and the 28A2 and described some 25A3 and the some 25A4 is more than 1/4, more preferably more than 1/3.
As shown in Figure 2, electronic component 40 is set on jockey 1.Electronic component 40 is that the IC encapsulation waits various electronic components such as being sealed with the IC nude film in body 41.Be provided with a plurality of projection electrodes 42 at the bottom surface of body 41 41a, the circuit turn-on in each projection electrode 42 and the body 41.The described projection electrode 42 of the electronic component 40 of this execution mode is a spherical form.In addition, projection electrode 42 can also be to cut out a cone shape etc.
As Fig. 5 and shown in Figure 6, on described connecting portion 20A, projection electrode 42 is set, the center of projection electrode 42 is consistent with the center O 1 of the elasticity wrist 22A of described connecting portion 20A, perhaps under roughly consistent state, when with body 41 when bearing-surface 12 is pressed, the elasticity wrist 22A of three-dimensional shape is damaged by pressure.Described elasticity wrist 22A is owing to being the space between described intersection point 28A1 and the intersection point 28A2, so the end portion of projection electrode 42 enters in this spatial portion.And then when damaging elasticity wrist 22A by pressure by projection electrode 42, the leading section 24A of spiral-shaped elasticity wrist 22A is pressed off the direction of leaving to from center O1.Elastic force when therefore, spiral-shaped elasticity wrist is opened by expansion mainly acts on projection electrode 42 from described leading section 24A.
Consequently, from elasticity wrist 22A projection electrode 42 is not only acted on the recuperability that will boost to the Z2 direction is arranged, and projection electrode 42 is also acted on the horizontal crimp force Fa that has along the face parallel with bearing-surface 12 from elasticity wrist 22A.Spiral helicine elasticity wrist 22A, near the O1 of its center is the space, because leading section 24A is in the position of leaving from center O1, so at the center of projection electrode 42 with the roughly consistent state of the center O 1 of elasticity wrist 22A under when depressing projection electrode 42, described horizontal crimp force Fa be configured to roughly the same towards.In the connecting portion 20A shown in Fig. 5 and Fig. 3 (A), act on from the leading section 24A of elasticity wrist 22A projection electrode 42 crimp force Fa vector towards be Y1 direction and X2 direction the centre towards, and be with respect to Y-axis and X-axis both sides be 45 degree angles towards.
As Fig. 3 and shown in Figure 4, connecting portion 20A, connecting portion 20B, connecting portion 20C, connecting portion 20D are respectively identical sizes, and essential structure is identical, but the surface configuration of substrate sheets 16 towards difference, form symmetrically in addition.
