Abstract: A method of dividing a two dimensional array of encapsulated integrated circuits into individual integrated circuit packages uses a first series of parallel cuts (32) extending fully through the leadframe (16) and encapsulation layer (14), and defining rows of the array. The cuts terminate before the beginning and end of the rows such that the integrity of the array is maintained by edge portions (34) at the ends of the rows. After plating contact pads (18), a second series of parallel cuts (36) is made extending fully through the leadframe (16) and encapsulation layer (14). This separates the array into columns thereby providing singulation of packages between the edge portions (34).

Abstract: A do-it-yourself wind power generation wall includes a plurality of wind power generation modules, each having a bushing, a wind power generation unit and a connecting rod. The exterior of the bushing forms a plurality of insert portions, and the wind power generation unit includes an electric generator connected to the bushing, and a vane wheel connected to the electric generator and formed on a side of the bushing, and an end of the connecting rod is sheathed onto an insert portion of the bushing, and each wind power generation module is connected to form a power generation wall. The invention allows users to freely install the power generation wall according to the environment of the application and greatly enhances the site and scope of using the power generation wall.
