Microvias: Links of Faith are Not Created Equally
07/18/2019 |
Jerry Magera and J.R. Strickland, Motorola Solutions Inc.
Microvias connect adjacent copper layers to complete electrical paths. There are copper-filled microvias, which can be stacked to form connections beyond adjacent copper layers, and staggered microvias, which stitch adjacent copper layers with paths that meander on the layers between the microvias. This article discusses the various laser-drilled microvias and presents SEM photographs to begin the search for the root cause of weak copper interface.

Multilayer organic laminates, which make up over 90% of the interconnecting substrates in electronics (standard FR-4 represents 85% of the substrates used for laminates), can develop a loss of electrical insulation resistance between two biased conductors due to conductive filament formation.
