Abstract:
There is disclosed herein a printed circuit board (PCB) having enhanced mounting pads useful for overprinting solder paste and for repair of the solder joints. The PCB comprises: a dielectric substrate 10 having at least one mounting pad 20 thereon, wherein each mounting pad is arranged in matched relation with a respective termination 32 of an electronic component 30. Each mounting pad 20 includes a main body portion 24 and one or more fingerlike extensions 26 extending outward from the main body portion and away from a projected footprint 34 of the electronic component.
Abstract:
A printed circuit board assembly includes two-dimensional arrays of connectors (14,16) to provide significantly higher data transfer rates than typical one-dimensionally arranged connectors, without sacrificing board space. The assembly includes a plurality of connection pads (14,16) on each printed circuit board (10,12). A layer of anisotropically conducting material (26) is placed between the connection pads and the boards are held together by fastening screws (28).
Abstract:
Electrical interconnection structures are described. The electrical interconnection structures are formed by electrically interconnecting in a stack a plurality of discrete substrates (22, 24). By using a plurality of discrete substrates, a multilayer dielectric/electrical conductor structure can be fabricated from individual discrete substrates each of which can be tested prior to forming a composite stack so that defects in each discrete substrate can be eliminated before inclusion into the stack. Electrical interconnection between adjacent substrate is provided by an array of contact locations on each surface of the adjacent substrates. Corresponding contacts on adjacent substrates are adapted for mutual electrical engagement. Adjacent contact locations can be thermocompression bonded. To reduce the parasitic capacitance and coupled noise between the contact pads (26) the electrical conductors within the interior of each discrete substrate, the contact pads on each substrate have elongated shape. The elongated contact pads or lattice pads on adjacent substrates are nonparallel and preferably orthogonal so that the corresponding pads of adjacent substrates electrically interconnect an intersecting area which varies in location along the elongated contact pads as the placement of the adjacent substrates varies in the manufacture thereof.
