SINGULATION OF IC PACKAGES

摘要

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).
