Abstract

Disclosed herein are structures and techniques for underfill flow management in electronic assemblies. For example, in some embodiments, an electronic assembly may include a first component, a second component, an underfill on the first component and at least partially between the first component and the second component, and a material at a surface of the first component, wherein the material is outside a footprint of the second component, and the underfill contacts the material with a contact angle greater than 50 degrees.
