Abstract:
1. A various electrical characteristics and small test point testing module comprised of a carrier plate, a guide correction layer, a clamp pin layer, a linear probe, a first cushioning component, a travel adjustment rod, a second cushioning component, a guide post, a base, and a tested object simulator block, wherein the said guide post is installed at the said base to provide for the vertical ascension and descension along the same axis of the said carrier plate, the said guide correction layer, and the said clamp pin layer; the said linear probe is utilized for testing a tested object; and a lead is used to transmit the test signal to a testing instrument, comprising: the said carrier plate has prefabricated, aligned insertion holes that accord with the test points of the said tested object; the said guide correction layer consists of a plurality of guide correction plates that are separated at an appropriate height and disposed with the said carrier plate into a unitary body, and each guide correction plate has guide correction holes that are in vertical or angular alignment with the said carrier plate insertion holes; the said clamp pin layer is situated along the inner side of the said guide correction layer, the insertion holes of which are in vertical or angular alignment with the said guide correction layer guide correction holes; the said first cushioning component is disposed in a plurality between the said guide correction layer and the said clamp pin layer, thereby providing the elastic force for raising and lowering the said guide correction layer and the said carrier plate; the said linear probes, the plurality of which is based on the quantity of said tested object test points, are respectively inserted into the said clamp pin plate insertion holes, the guide correction plate guide correction holes, and the said carrier plate insertion holes such that their inner extremities are fixed at the said clamp pin layer and their outer extremities simultaneously contact and are aligned with the said test points when the said tested object undergoes testing; the said travel adjustment rod is installed between the said guide correction layer and the said clamp pin layer and has a predisposed set interval, such that it determines the distance of the said linear probe outer extremities at the said tested object and when the said carrier plate and the said guide correction layer are subjected to pressure for internal movement; the said second cushioning component is disposed between the said clamp pin layer and the said base to thereby directly provide an equal magnitude of elastic force to the said linear probes fixed onto the said clamp pin layer; one end of the said lead is connected to the testing instrument and the other end is directly installed to the said linear probe inner extremity; the said tested object simulator block is stacked on the bottom surface of the overturned said carrier plate, its surface defined by the positions and height of the said tested object test points and disposed in an identical state such that when the said linear probes are installed, their outer extremities can be utilized against test point; whereby, when pressure is applied to the said tested object on the said carrier plate during a testing operation, the said carrier plate and the said guide correction layer undergo elastic internal movement until the outer extremities of the said linear probes extend to the set length and under equal elastic pressure simultaneously contact and are aligned with the said test points, with test signals then transmitted to the testing instrument via the said leads installed at the inner extremities of the said linear probes.
