Abstract

See full text

A package-on-package (“PoP”) structure and a method of forming are provided. The PoP structure may be formed by forming a first set of electrical connections on a first substrate. A first material may be applied to the first set of electrical connections. A second substrate may be provided having a second set of electrical connections formed thereon. The first set of electrical connections of the first substrate having the epoxy flux applied may be contacted to the second electrical connections of the second substrate. A reflow process may be performed to electrically connect the first substrate to the second substrate. The epoxy flux applied to the first electrical connections of the first substrate may prohibit electrical bridges or shorts from forming during the reflow process.
