Abstract
An SMD includes a substrate and one or more electrical contacts on a first surface of the substrate. Each one of the electrical contacts are configured to couple to a corresponding electrical contact located on a surface of a carrier, and are located within a concentric area of the first surface that is less than about 50% of a total area of the first surface. By providing the electrical contacts within the concentric area, the mechanical stress experienced by the electrical contacts can be significantly reduced when compared to conventional SMDs including electrical contacts on the outer edges thereof. Accordingly, the failure rate of the SMD due to separation of one or more of the electrical contacts from the carrier may be reduced.
