Step 1 Development ✓ Online

Inspect 3D Enclosure CAD Files in WebGL

Launch Fomrix STL Viewer (No Login) ↗
Input Binary / ASCII STL
Output 3D WebGL Viewport Inspection

Drag-and-drop binary or ASCII .stl enclosure files directly into Fomrix STL Viewer. Rotate, pan, zoom, inspect internal mesh facets, and verify dimension clearances in real-time without uploading 3D CAD models to remote servers.

💡
Pro Tip: Toggle wireframe mode to check whether high-density polygon regions have manifold holes or non-manifold geometry before sending to 3D printing.

Step 2 Development

Simulate Multilayer PCB Gerber Fabrication

Launch Salitronic Gerber Analyzer (No Login) ↗
Input Gerber / ODB++ / Drill ZIP Archive
Output Layered PCB Stackup Visualization

Load standard RS-274X Gerber, ODB++, and drill archives into Salitronic Gerber Analyzer. Review copper pour layers, silkscreen alignment, solder mask bridges, and thermal relief pads completely client-side in the browser.

💡
Pro Tip: Inspect the top and bottom solder mask layers closely around fine-pitch QFN and BGA footprints to identify potential solder bridging defects.

Step 3 Productivity

Compute Microstrip Impedance & Trace Current

Launch Omni Calculator (No Login) ↗
Input PCB Geometry Parameters (mil / mm)
Output Characteristic Impedance (Ω) & Temperature Rise

Input copper thickness, substrate dielectric constant (FR-4), and trace width into Omni Calculator's engineering models. Calculate single-ended 50-ohm characteristic impedance and maximum safe amperage before manufacturing.

💡
Pro Tip: For high-speed USB differential pairs or SPI clocks, adjust trace separation to achieve matching 90-ohm or 100-ohm differential impedance targets.

Why This Stack Beats Cloud SaaS

Hardware prototyping and electronic fabrication teams frequently risk leaking proprietary CAD designs and PCB layouts to third-party cloud viewers. This client-side engineering stack enables mechanical engineers, hardware hackers, and PCB designers to visually inspect 3D STL enclosures, simulate circuit board Gerber layers, and compute electrical parameters without uploading a single engineering file to private servers.

Industrial engineering files carry sensitive intellectual property. By combining WebGL 3D model parsing in Fomrix STL Viewer with Salitronic's browser-side Gerber simulation and Omni Calculator's electrical trace modeling, you achieve rapid design verification without non-disclosure agreement (NDA) compliance concerns.

Frequently Asked Questions

Do my proprietary 3D models or PCB Gerber files leave my computer?

No. Fomrix STL Viewer and Salitronic Gerber Analyzer execute their rendering engines entirely within client memory using WebGL and browser Canvas APIs. Files are read via the HTML5 File API and never uploaded to remote servers.

Can I inspect drill files and multiple copper layers simultaneously?

Yes. Salitronic Gerber Analyzer parses standard Excellon drill files alongside top/bottom copper, silkscreen, and solder mask layers with independent layer toggle visibility and opacity controls.
