Real calculators powered by IPC standards. AI copilots built on real PCB data. Use them anonymously — your inputs never leave your browser unless you ask them to.
Calculators
Deterministic, formula-grade. IPC + measured-data correlated.
Z₀
Impedance calculator
Microstrip + stripline + edge-coupled differential. IPC-2141 / Polar-grade math.
Open →I_max
Current carrying capacity
External + internal traces, IPC-2221/2152. Pick a temperature rise; get a trace width.
Open →Via·A
Via current rating
How much current a finished via can carry before plating limits. IPC-2152 barrel ampacity.
Open →IR
Voltage drop
Trace resistance, IR drop, and power dissipated — from geometry, current, and temperature.
Open →Σ
Thermal via array
How many vias under your QFN, what diameter, what plating — and the θ you’ll get.
Open →Φ
Φ Thermo — heatmap estimator
Place components, set power, see the steady-state heatmap in milliseconds. Honest 2D FDM, no install.
Open →Z
Φ Z-PDN — target-impedance visualizer
Build a decoupling-cap rack, set the rail and transient step, watch |Z(f)| cross or stay under the target line. Series-RLC, log-log plot.
Open →AI copilots ⌁ live
Built on PhyCircuit’s 20 years of design data + Anthropic Claude. Always cite their reasoning.
Φ
Φ DFM Translator
Paste a fab DFM report. Get plain-English explanations + Altium fixes per error.
Open →Φ
Φ Stack — Stackup builder
Pick a layer count + class + target impedance. Get a canonical stackup with cross-section — and one click for 3 AI alternatives.
Open →Φ
Φ Gerber — AI review
Drop a Gerber zip. Get an annotated review: stackup, missing layers, drill sanity, format flags.
Open →Φ
Φ Datasheet — Q&A
Drop any chip datasheet PDF. Ask “what’s Vth at 85 °C?” Get a cited answer.
Open →Φ
Φ BOM — Sanity bot
Drop your BOM. See EOL risks, single-source bombs, lifecycle warnings, substitutes.
