The article offers information on package-on-package (POP) assembly which can help electronic manufacturers cram more functions into smaller devices. The entry describes a POP assembly as two or more fine-pitch ball grid arrays (BGA) that are stacked on top of each other. In relation to this, a POP assembly is produced using the standard surface-mount process with the BGA fed from tape or trays. Also reported is Henkel's introduction of an epoxy molding compound that minimizes warping of POP assembly.
