Abstract:
The present invention relates to a circuit board of DSLAM and an arrangement to minimize thermal flow or electro-magnetic radiation from digital side to analog side, or vice versa. The circuit board comprises analog components and passive digital components on first side of the circuit board and active digital components on the second side of the circuit board. The arrangement comprises an enclosure having the circuit board with analog components, passive digital components, and active digital components and a first component connected between the first portion and the second portion of the circuit board to restrict thermal flow or electromagnetic radiation from one portion to another portion.
Abstract:
A means is described of connecting multiple flexible printed circuit (FPC) tags. The means is suitable where electrical circuitry has been printed or otherwise applied to one side of flexible substrates, and where the circuitry of two such substrates is required to be brought into electrical continuity. In this method, a sewing, stitching or embroidery machine is used to hold juxtaposed conductive surfaces in electrical continuity by tension. In a variation of the means, conductive thread, wire or other material is used to create an electrically-conducting via between the relevant conductive surfaces of two or more such FPC tags.

A fixing component of a main board comprises a connecting part, a thread-assembling part and a fixing part. The connecting part has a first surface and a second surface, wherein the first surface is disposed opposite to the second surface. The thread-assembling part is disposed on the first surface of the connecting part. The fixing part is disposed on the second surface. The connecting part and the fixing part are disposed on a main board by utilizing DIP technology and SMT.
Abstract:
A method for attaching an IC package to a circuit board, the IC package having a plurality of electrical contacts in an arrangement having a perimeter, first positions the IC package adjacent to the circuit board. Then, electrically connects the IC package to the circuit board through the plurality of electrical contacts. The method finally, disposes at least one anchor mechanically attaching the IC package to the circuit board, the anchor disposed at a location outside of the perimeter of the plurality of electrical contacts. The type, quantity, and exact geometry of the anchors depend on the specific design parameters of the IC package and circuit board.
Abstract:
An assembly for coupling an electrical device with a rigid structure using a flex circuit is provided. The assembly includes a staple having posts which extend into the rigid structure and secure the staple to the rigid structure. The flex circuit couples with both the rigid structure and the electrical device. The flex circuit extends between the staple and the rigid structure such that the flex circuit couples with the rigid structure thereby providing an interconnection between the electrical device and the rigid structure.
Abstract:
A printed circuit board defective area transplant repair method in which printed circuit boards that are determined to be defective undergo a series of reworking procedures comprised of plotting the printed circuit board area block plan, selecting the printed circuit boards, cutting out the area blocks, cutting the selected area blocks, applying the adhesive and fitting area blocks, adjusting the area block alignment, roller tamping the plastic band, curing the adhesive, and tearing off the plastic band. Following the reworking operations, defective printed circuit boards are restored into a good products capable of continuous use such that printed circuit board fabrication and production is even more economical and environmentally protective and, furthermore, printed circuit board manufacturing reaches maximum utilization rates, thereby effectively increasing practical production value.

Abstract:
A fastening device for facilitating temporary fastening of an electronic component to a circuit board. The fastening device includes a base embedded in an electronic device and two elastic plates extending from the base. Each elastic plate includes a diagonal portion, which extend diagonally relative to the plane of the circuit board, and a leg, which extends continuously from the diagonal portion. When the legs are inserted through a connecting hole of the circuit board, the resilient force of the elastic plates presses the diagonal portions against the wall of the connecting hole.
