The practical minimum microvia diameter HDI is set by plating reliability and aspect ratio, not laser limits. Stay above 75 µm with design margins to avoid voids, thin copper and reliability failures.
Factory view on HDI BGA pad clearance: how CAM catches tight clearances, why registration stack-up creates short risks, and the process controls that stop yield loss and shipment delays.
HDI fiducial placement decides SMT accuracy on high-density boards. See the exact CAM rules, local mark positions near BGAs, and what fails when marks are missing or covered.
From PCB production: when HDI thermal relief is applied on via/pad-to-plane connections for controlled soldering heat, how CAM sets spoke widths, and when solid connections stay.
Factories enforce 3.5–5 mil HDI copper pour clearance after etch. See why tight pour-to-via/pad gaps cause shorts, how CAM compensates, and when exceptions are allowed.
Factory view on HDI solder mask expansion: why CAM flags oversize or undersize openings, pad bridging risk on fine pitch, and the exact expansion window (0.025–0.05 mm) we enforce to protect yield.
Factory method for HDI microvia solder mask: CAM opening expansion, registration compensation, bridging control and residual-ink checks that protect soldering yield.
