Abstract:
Disclosed is a testing apparatus, including: a base having opposite upper and lower surfaces, and a plurality of electrical circuits formed in the base, each of the electrical circuits extending from the upper surface to the lower surface and bending backwards to the upper surface such that two terminal ends of the electrical circuit are located on the upper surface. While in a testing, an element is disposed on the upper surface of the base such that testing probes are placed on the electrical contact spots of both the element and the upper surface of the base, thus without resorting to double sided testing that testing probes are placed on the upper and lower surfaces of the element as mentioned in the prior art. Hence, the testing apparatus and testing method can simplify the testing process and prevent the element from damage caused by mechanical stresses of the testing probes.

Abstract:
An asymmetric differential inductor includes first and second conductive wirings spirally disposed on a substrate having a first input terminal, a second input terminal, a ground terminal, and a central conductive wiring. The central conductive wiring has a central contact connecting the ground terminal and a central end away from the ground terminal. The first conductive wiring extends across the central conductive wiring and has a first contact connecting the first input terminal and a first end connecting the central end. The second conductive wiring extends across the central conductive wiring and interlaces with the first conductive wiring and has a second contact connecting the second input terminal and a second end connecting the central end. Corresponding portions of wiring sections of the first and second conductive wirings at opposite sides of the central conductive wiring are asymmetrical to one another to thereby save substrate space and facilitate circuit layout.

An interconnecting mechanism is provide, which includes paired first sub-interconnecting mechanisms and paired second sub-interconnecting mechanisms. The first pair of sub-interconnecting mechanisms includes first and second axially symmetrical spiral conductive elements. The second pair of sub-interconnecting mechanisms includes third and fourth axially symmetrical spiral conductive elements. Configuring the pairs of sub-interconnecting mechanisms in a differential transmission structure having a spiral shape is used to avert sounds and noise signals between different chips or substrates caused by a miniaturizing fabrication process or an increased wiring density.
Abstract:
A symmetric differential inductor structure includes first, second, third and fourth spiral conductive wirings disposed in four quadrants of a substrate, respectively. Further, a fifth conductive wiring connects the first and fourth spiral conductive wirings, and a sixth conductive wiring connects the second and third spiral conductive wirings. The first and second spiral conductive wirings are symmetric but not intersected with one another, and the third and fourth spiral conductive wirings are symmetric but not intersected with one another. Therefore, the invention attains full geometric symmetry to avoid using conductive wirings that occupy a large area of the substrate as in the prior art and to thereby increase the product profit and yield.
