Abstract
Various exemplary embodiments relate to a printed circuit board (PCB) for electrically connecting a discrete array component including a pattern formed on the PCB which is a merger of a set of via pads and a discrete array component; wherein the pattern is generated by a pin mapping between the discrete array component and a via grid array on the PCB; and wherein the pattern is formed of a metal etched during a manufacturing process of the PCB.
Claims11
A computer aided design (CAD) tool implemented on a computing device for soldering a discrete array component on a printed circuit board (PCB) for use with mounting a component comprising:
- a design tool mode configured to identify a placement of the discrete array component on the PCB and to verify whether pin mapping between the discrete array component and a ball grid array (BGA) on the opposite side of the PCB is feasible;
- a design tool mode configured to determine the geometry of a design via grid of a set of via pads to be associated with the discrete array component and a geometry for the discrete array component;
- and
- a design tool mode configured to generate a merged pattern on the PCB associated with a merger of the design via grid of the via pads and a land pattern of the discrete array component sharing a same space on the PCB.
A computer aided design (CAD) tool implemented on a computing device for soldering a discrete array component on a printed circuit board (PCB) for use with mounting a component comprising:
- a design tool configured to allow a selection of a design via grid of vias to be formed and arrangement of a solder mask, component pads, and the selection of vias to be substantially automated, wherein the design tool automatically identifies appropriate spacing and shape of a solder pad to allow placement of surface mount components on one side of the PCB, wherein a ball grid array (BGA) is to be placed on the opposite side of the PCB,
- wherein the design tool automatically tests and merges copper patterns in their design on top of the PCB and wherein the merging is of the design via grid of vias and land patterns of the discrete array component sharing a same space on the PCB.
