IPC-WP-023 is an IPC Technology Solutions White Paper addressing reliability issues associated with stacked microvias. There is evidence that staggering vias can result in a more robust structure; however, staggering microvias is only a temporary solution to accommodate complex designs with microvias built with weak interface structures

IPC-WP-023 white paper provides an investigation of these issues using data collected from multiple printed board manufacturers and research conducted by the author.
