Achieving OSAT and foundry fabrication rules for package substrate outgassing, metal-filled areas and power planes
Dynamic hatched fill, outgassing voids, and dummy metal fill are the most common methods to achieve foundry and OSAT requirements for metal areas and planes in advanced package designs. The key to success lies in choosing the methodology that best meets vendor rules and design power specifications, allows rapid ECO turns, and is repeatable. This paper describes these three methodologies.
