Why HDI PCB Manufacturing Starts Long Before the First Hole Is Drilled
When people think about PCB manufacturing, they usually imagine drilling, plating, imaging, etching, solder mask, and surface finishing.
For conventional PCBs, that assumption isn't too far from reality.
For HDI (High Density Interconnect) PCBs, however, manufacturing actually begins long before any physical production starts.
The success of an HDI project is often determined during engineering review rather than on the factory floor.
