Abstract
A printed circuit substrate may be configured with at least one internal lead designed and shaped to reduce solder bridging. The printed circuit substrate can have a plurality of internal leads that each has a continuously curvilinear boundary that defines an isolation channel. The isolation channel may be configured with a uniform distance that separates a first internal lead from an adjacent second internal lead.
Claims21
An apparatus comprising a printed circuit substrate comprising an internal lead with first, second, and third bonding areas each having a continuously curvilinear boundary and aligned along a common axis, the second bonding area having a greater surface area than the respective first and third bonding areas, the second bonding area positioned closer to the third bonding area than the first bonding area.
An electrical device comprising a printed circuit substrate comprising first and second internal leads, each internal lead having a continuously curvilinear boundary defining an isolation channel and first, second, and third bonding areas aligned along a common axis, the isolation channel positioned between the first and second internal leads and having a first isolation distance separating the third bonding areas of the first and second internal leads and a second isolation distance separating the second bonding areas of the first and second internal leads, the first separation distance being smaller than the second separation distance, the second bonding area of each internal lead having a greater surface area than the respective first and third bonding areas, the second bonding area of each internal lead positioned closer to the third bonding area than the first bonding area.
An apparatus comprising a printed circuit substrate comprising a first internal lead with first, second, and third bonding areas each having a continuously curvilinear boundary and aligned along a common axis, the second bonding area positioned between the first and third bonding areas and having a greater surface area than the respective first and third bonding areas, the second bonding area positioned closer to the third bonding area than the first bonding area.
