Abstract
A method of forming a packaging structure and the packages formed thereof are provided. The method includes providing a package having a top surface and placing solder balls on the top surface of the package. A coplanar surface is then placed against the solder balls, wherein the surface is non-adhesive. A reflow process is performed to the solder balls, so that top surfaces of the solder balls are substantially coplanar. The coplanar surface is then removed.
