Resources
DFM and DFA guides, Gerber and centroid file checklists, glossary and a trace-width calculator.
Practical guides for hardware teams
Clear design rules, correct file formats and realistic tolerances remove most of the back-and-forth in a PCB order. These resources are the same references our engineers use during DFM review.
DFM Guidelines
Minimum trace, spacing, annular ring, solder mask and panelization rules that avoid review delays.
Open resource
DFA Guidelines
Component spacing, fiducials, orientation, tooling holes and test access for smooth assembly.
Open resource
Gerber & Centroid Files
What to export, how to name layers and which checks prevent a delayed or mis-built order.
Open resource
PCB Glossary
Plain-language definitions for the PCB and assembly terms used in quotes and DFM reports.
Open resource
Trace Width Calculator
Estimate trace width from current, temperature rise and copper weight using the IPC-2221 approximation.
Open resourceTwo tools that save a design cycle
Trace width calculator
Estimate the copper width you need for a given current and temperature rise, using the IPC-2221 approximation with a 20% safety margin.

DFM guidelines
Minimum annular ring, solder mask clearance, panelization and impedance rules — the checks that most often trigger a question during review.
