Meeting Miniaturization Demands
Miniaturization of electronic devices is driving the need for highly reliable metallization that can connect ever smaller metal lines and vias on advanced HDI boards. Designs include laser-drilled blind microvias as well as through holes with high aspect ratios. Both types of vias need to be filled completely without depositing excess copper
