PCB Design Pros/Cons, DFM Risk & Cost-Down Engineering Audit
Pinpoints isolated <4mil traces or redundant drill diameters (<2% of board) that trigger advanced tier surcharges.
Audits untented Via-in-Pad solder wicking risks, Top/Bottom copper coverage symmetry (bow/twist prevention), and panel efficiency.

Frequently Asked Questions — Online Gerber Viewer
Are my uploaded Gerber design files kept strictly confidential?
Yes. All Gerber archives are transmitted via encrypted TLS, processed in isolated sandboxes, automatically purged within 24 hours if unordered, and can be deleted immediately with 1 click.
Do I need to re-upload my Gerber file when moving to the Quote page?
No. PCBPath carries your cloud file key, extracted CAM parameters, and any solder mask, silkscreen, surface finish, thickness, or quantity choices directly into Standard, Advanced, or Flex PCB Quote.
Which EDA packages and Gerber formats are supported?
We support RS-274X, Gerber X2, ODB++, IPC-2581, and Excellon 1/2 drill files exported from Altium Designer, KiCad, Eagle, EasyEDA, Cadence Allegro/OrCAD, PADS, and DipTrace.
Why does high zoom stay crisp instead of becoming blurry pixels?
Unlike basic image viewers, PCBPath combines 2560px lossless WebP layer masks for instant color compositing with true CAD vector Path2D primitives when zooming above 250%.
How does the AI + 2D CAM Engineering Audit help reduce PCB cost by 15%–40%?
Many PCB quotes jump into expensive fabrication tiers because less than 2% of traces (<4 mil) or a single isolated micro-via (<0.20 mm) exceed standard design rules, or because drill tables contain nearly identical tool diameters. Our audit pinpoints exact (X, Y mm) coordinates of these cost bottlenecks so you can relax them back to standard pricing.
Which DFM manufacturability metrics can I inspect and export?
Beyond the 18-rule CAM check (trace/space, annular ring, drill-to-copper, board outline closure), the audit evaluates Top/Bottom copper coverage symmetry (bow & twist risk), standard 457×610 mm panel utilization, untented Via-in-Pad solder-wicking risks, and recommended laser stencil thickness—exportable in Excel (CSV), Markdown, or JSON.
