Abstract:
Disclosed is an apparatus for optimally facilitating interconnections between electrical endpoints. The apparatus comprises a number of terminals equal to a number of combinations of the plurality of endpoints. For example, to enable combinations of two endpoints to be made between N endpoints, the apparatus comprises N(N−1)/2 terminals. Each terminal at least comprises a first contact coupled to a first endpoint and a second contact coupled to a second endpoint. The first contact and second contact of any terminal can be shorted to connect their corresponding endpoints. The apparatus may further comprise a circuit identification process executed by a microcontroller. In this case, each terminal additionally comprises a first circuit identification contact and a second circuit identification contact. The process involves outputting a voltage to the first circuit identification contact and detecting the voltage of the second circuit identification contact to determine whether the corresponding terminal is activated.
Abstract:
A circuit board with wire conductive pads is provided for insertion of wires, and includes: a circuit board and a wire conductive pad. The wire conductive pad includes a main body in the form of a hollow column and an elastic locking piece extending from the main body. The main body includes a peripheral wall defining an insertion space. The elastic locking piece is inserted from the peripheral wall into the insertion space in an inclined manner to press towards the peripheral wall. Wires are inserted into the insertion space and clamped against the peripheral wall by the elastic piece, so that the wires can be prevented from falling off in a reverse direction, and thus can be connected to the circuit board in a more quick and stable manner.

A fabricated substrate has at least one plurality of posts. The plurality is fabricated such that the two posts are located at a predetermined distance from one another. The substrate is exposed to a fluid matrix containing functionalized carbon nanotubes. The functionalized carbon nanotubes preferentially adhere to the plurality of posts rather than the remainder of the substrate. A connection between posts of the at least one plurality of posts is induced by adhering one end of the functionalized nanotube to one post and a second end of the functionalized carbon nanotube to a second post.
Abstract:
A method for manufacturing a circuit board system comprising mechanical protection of electrical components is presented. The circuit board system comprises a circuit board (101) furnished with electrical components (103-111) and a protection element (102) attached to areas of the circuit board which are free from the electrical components. The protection element has thickness in the direction perpendicular to the circuit board and it is shaped to leave the electrical components unscreened in the direction perpendicular to the circuit board. Thus, the protection element constitutes barriers protecting the electrical components but still allows the electrical components to be accessed from the direction perpendicular to the circuit board for example in a flying probe testing. Furthermore, the protection element provides electrical connections between functional entities of the circuit board system.
