Optimization of laminate condition for Resin Coated Foil by Quality Engineering

Abstract

Resin Coated Foil (RCF) for thinner multilayer boards (MLBs) need not only high heat resistance, low CTE and low dielectric constant but also to satisfy layer thickness, uniformity and filling up inner layer pattern in laminate process. Press cycle (heating ratio, temperature profile, pressure etc.) in laminate process was determined through trial and error in the past. We applied Quality Engineering to optimize the laminate condition of the RCF with effectiveness and concreteness.
