Stacked vs staggered microvias is primarily a routing-density and reliability decision. Staggered microvias usually provide a lower-risk structure when the
PCB microvia reliability depends on the integrity of the copper connection between a laser-drilled microvia and its target pad. A
PCB IST testing heats and cools a representative coupon while continuously monitoring the resistance of its plated holes, vias, and
PCB copper ductility describes how much electrodeposited copper can deform before it fractures. It helps explain why a plated through
PCB throwing power describes how effectively an electroplating process deposits copper inside a through hole compared with the board surface.
PCB electroless copper creates the first continuous conductive layer on drilled hole walls before electrolytic copper plating. The process succeeds
The PCB desmear process removes heat-smeared resin, drilling debris, and other contamination from drilled hole walls before metallization. A hole
PCB Resin Recession occurs when resin withdraws from the plated hole barrel or surrounding glass structure, usually after thermal exposure.
PCB Interconnect Defects are separations at or near the connection between an inner-layer copper feature and the metallization inside a
