Description
Technical field
The utility model is relevant with probe, is meant a kind of adjustable probe seat in detail.
Background technology
Press, probe mainly utilize most probes as with thing to be tested between electrically contact, to be used in test chip, display panel or other carries out temporary electrical contact.
Those probes must be fixed in one and be linked on the probe base of circuit board, and keep those probe tips at a distance of predetermined distance, with the corresponding weld pad spacing of being desired to carry out on the test chip.So, because the distance between these a little needle points must be leaned on manually when being attached to each probe on the probe base, control in advance seriatim (promptly be about to again after the distance between those needle points of control earlier probe be attached on the probe base), this kind package program is not only complicated more very easily to be taken place to have after those probes stick together between the needle point apart from incorrect situation, the probe base integral body that causes sticking together those probes is removed, install a probe base more separately on circuit board, the operation that you stick together probe more again.
Moreover, because being made of metal to be made with the ceramic component that anticreep effectiveness is provided by pottery with the hardware and that structural rigidity is provided by one, probe base formed jointly, hardware is locked on the circuit board, ceramic component then is connected on the hardware with sintering processing, to stick together for each probe, with the needle tip spacing that is maintained fixed by ceramic component.Yet, because the needle tip spacing of each probe, must corresponding to desire to carry out weld pad spacing on the test chip, therefore when desiring to carry out that the chip of different weld pad spacings done engaged test, then each probe and ceramic component must be removed in the lump together with being sintered to fix the hardware that is one, again install a probe base again on circuit board, stick together with the probe that carries out different needle tip spacings again; Therefore when carrying out the chip testing of different weld pad spacings at every turn, the probe that must remove one group of probe base again and be attached to then, again be installed in one group of probe base that has the probe of different needle tip spacings and stick together mutually on the circuit board again, not only job procedure is comparatively numerous and diverse, more is easy to generate the thing of waste probe base and probe thereof.
In addition, because above-mentioned disappearance, then there is the dealer to research and develop a kind of probe base relevant position of adjusting, reach the probe base of control probe arrangement position with this, as Japanese patent laid-open 10-90305 patent case, only this structure is directly to utilize stainless steel or the aluminium material as probe base, and Yi Fashengyin thermal expansivity and other member difference are excessive and poor heat radiation that cause reaches the thing that electric leakage is easily arranged.
