摘要： According to an exemplary implementation, a power quad flat no-lead (PQFN) leadframe includes U-phase, V-phase, and W-phase power switches situated on the PQFN leadframe. A drain of the U-phase power switch is connected to a U-phase output strip of the PQFN leadframe. A source of the U-phase power switch is connected to a U-phase current sense terminal. The U-phase output strip can substantially traverse across the PQFN leadframe. Another U-phase power switch is situated on the PQFN leadframe with a source of the another U-phase power switch connected to the U-phase output strip of the PQFN leadframe. The PQFN leadframe can include a leadframe island within the U-phase output strip. At least one wirebond may be connected to the U-phase output strip.

摘要： Micro-channel-cooled UV curing systems and components thereof are provided. According to one embodiment, a lamp head module includes a high aspect ratio, high fill factor array of light emitting devices and a submount. The array includes multiple groups of electrically seriesed light emitting devices that are connected in electrical parallel. The submount is of monolithic construction and includes multiple re¬ shaped patterned circuit material layers. Each of the L-shaped patterned circuit material layers includes an arm portion and a stem portion. The arm portion functions as a light emitting device bond pad and the stem portion functions as a wire bond pad and a circuit trace. Each light emitting device of a group is affixed to a corresponding arm portion of the submount. The stem portions are located external to the array, run parallel to the length of the array and perform a primary current carrying function for current flow between adjacent light emitting devices of the group.
