    Abstract: This invention relates to a substrate with via and pad structure(s) to reduce solder wicking. Each via and pad structure connects a component to conductive layers associated with the substrate. The substrate includes one or more plated vias, solder mask(s) surrounding the plated vias, and a conductive pad with a conductive trace connected to each plated via. The conductive pad extends beyond the terminal sides to increase solder formation and the solder mask reduces solder formation at the terminal end of the component. The via and pad structure is suitable for a variety of components and high component density. The invention also provides a computer implemented method for calculating the maximum distance of a conductive pad extending beyond the terminal side of a component.

    Abstract: A printed wiring board is provided in which lift-off and land peeling do not occur during soldering of an inserted component onto the printed wiring board, and hence pattern breakage does not occur, but with no increase in cost. A plurality of lands 6 are each formed continuously across surfaces of a substrate and an inner peripheral surface of one of a plurality of soldering through holes 5 into which leads 2 of an inserted component 3 to be mounted onto the printed wiring board are inserted before soldering is carried out, and a solder resist 8 is coated onto the lands 6.

    Abstract: A method of fabricating a solder bumped substrate for a flip-chip integrated circuit (IC) package is provided. The method includes the following steps. Providing a substrate material. Patterning a conductive layer on the substrate material that includes a plurality of circuit traces coupled to a plurality of bonding pads, wherein the bonding pads are arranged to correspond to input/output (I/O) pads on the flip-chip IC. Fabricating a solder mask layer over the conductive layer, wherein the solder mask layer defines a pad opening corresponding to each of the bonding pads, and wherein the pad openings defined by the solder mask layer are tapered such that each pad opening includes an expanded end and a tapered end. Printing solder onto a portion of each bonding pad that is exposed by the expanded end of the corresponding pad opening. Reflowing the printed solder to form solder bumps on each bonding pad.
