When mission failure is not an option, everyday commercial board standards will not suffice. At PNC Inc., we specialize in advanced IPC-6012 Class 3 (Class III) rigid printed circuit board fabrication. Every single board is manufactured from concept to completion at our secure, ITAR-registered facility in Nutley, New Jersey—ensuring flawless execution for high-reliability military, aerospace, and critical medical electronics.
We maintain rigid drill-to-copper positioning controls to ensure compliance with strict Class 3 annular ring parameters. Our processing layout guarantees a minimum of 2 mil external and 1 mil internal annular rings with absolutely no external breakout permitted, protecting your vias from thermal stress fracturing.
Our electroplated acid copper processes are calibrated to meet the increased demands of IPC-6012 Class 3 specifications. We enforce a strict 25 µm (1 mil) minimum hole wall copper plating thickness and achieve an accelerated 75% vertical barrel fill requirement during automated soldering configurations.
PNC Inc. combines deep technical heritage with automated, high-mix facility capabilities to handle up to 40-layer high-density multilayer configurations under one roof:
