. A common application for this is on a BGA design where vias are commonly found in very close proximity to the BGA’s SMD pads. The concern is during assembly, solder will wick away from the intended pad and flow down the via creating poor or non-existent solder joints. Via Filling

(High Density Interconnect) technology is increasingly becoming the solution for smaller, more durable, and more efficient PCBs. HDI technology allows for lighter, smaller products that do more faster than ever before by leveraging blind and buried vias that can be staggered, stacked, and integrated with microvias
