Description
Technical field
The present invention relates to probe, more detailed be meant a kind of stretching type folding probe.
Background technology
In semi-conductor industry, when making an integrated circuit (IC) chip but do not carry out as yet encapsulation procedure before, must be earlier through the circuit function of a trace routine test chip; Generally be to utilize a probe to be located between tester table and the chip to be measured, probe is then by the probe by various types, as rectilinear, cantilevered, spring probe ... Deng as with the contacting of chip chamber to be measured, to transmit signal in tester table and chip to be measured.
But the probe with most in the market is mainly single cantilever beam structure, and its advantage is that structure is simple, and needle point can approach to less needle gage, and low manufacturing cost; But because of the restriction of Material Strength and needle gage, for enough elastic deformation amounts and pin weight can be provided, it is long often need to possess an enough pin, and long pin length can't be in response to layout semiconductor test demand more and more closely.
For avoiding above-mentioned disappearance, then there is the dealer to research and develop a kind of leafy probe, as No. the 6672875th, United States Patent (USP), as shown in Figure 1, it has the cantilever 2 and a needle point 3 of a fixed part 1, majority, and these cantilevers 2 are to be to be connected in this fixed part 1 one sides with the one end side by side, and 3 at this needle point is connected on the one cantilever 2 contiguous free-ended end faces of the superiors; Though this kind structure can be by being out of shape so that the higher integral, flexible of more single semi-girder to be provided by rigidity that reduces each cantilever 2 and then reduction maximum stress, but 2 on each cantilever easily produces mutual friction and causes loss, make its fiduciary level relatively poor, moreover the heavy quantity that then need increase cantilever 2 of pin as if desiring to provide enough makes its complexity higher; Otherwise, to avoid multilayer cantilever number and providing under the consideration of enough cantilever rigidity, its cantilever pin length can't effectively be reduced, and can not satisfy the cloth pin demand of high density, low needle point distance.In brief, No. 6672875 disclosed leafy probe of United States Patent (USP) can't be taken into account the needs that reduce the structure maximum stress and improve the cloth pin density simultaneously.
In view of this, this United States Patent (USP) case also discloses the shortcoming that the leafy compression probe that other type is arranged can overcome aforesaid leafy probe No. 6672875, as shown in Figure 2, therefore its rigidity of folding elastic construction of the leafy compression probe of class is equivalent to many groups cantilever design in parallel, its integral rigidity reduces compared to single cantilever design, can shorten this pin length at the same time so that enough needle body rigidity to be provided; Again this while, via suitable design, the structures of many foldings can be dispersed in each horizontal beam spare with stress, can take into account simultaneously and reduce maximum stress and improve the long needs of cloth pin density shortening pin.
Yet the leafy compression probe that this United States Patent (USP) case is disclosed for No. 6672875 still has following disappearance:
1. this type of compression elastic body design is subject to the restriction of compression pin the ratio of width to height, the conventional springs design reference is restricted to 5 when the elastomeric width of compression and aspect ratio are excessive, the compression elastic body is easy to generate the side direction collapse, causes the not good situation of structural stability.In view of this, when facing tiny needle apart from demand, the needle body width of this leafy compression probe also must with reduction, yet because of limited compression elastic body the ratio of width to height principle of design, its pin is high can't be too high, and the leafy structure of multilayer promptly can't be arranged, add between each blade 4 and must reserve enough elastic compression deformation spaces, the number of leafy structure into is more limited with making, and then causes and can't bring into play the purpose that reduces maximum stress, makes the design's usefulness limited.
2. this preceding case emphasizes that designed needle point 5 and its fixed part 6 are positioned on the same Z-axis simultaneously, it is designed that its application is primarily aimed at the test probe of vertical start, possess small size lateral shift yet but can't satisfy, scratch chip surface oxide to be measured to promote the demand of electrical contact with this needle point pin trace that draws by this for some needs needle points.
Therefore, case of the present invention will propose a stretching type folding probe, not only can take into account and reduce max architecture stress and improve the cloth pin density and shorten the long demand of pin, also solve the disappearance of the leafy compression probe that the United States Patent (USP) case disclosed for No. 6672875 simultaneously.
