WebAug 31, 2024 · Laser microvias most commonly span a single layer, resulting in a structure with aspect ratio typically ranging from 1:2 to 1:1. The low aspect ratios that are easily and accurately accessible with laser drilling makes this process ideal for blind and buried vias. WebOct 16, 2024 · Photo-defined vias are commonly used to create multilayer organic BGA (ball grid array) packages and cell phone PCBs. The advantage in using them is that it costs the same to create thousands of blind vias as it does to create just one.
