60-second PCB tour
Scroll-driven storytelling. Watch a BGA fan out, see traces route through layer transitions, follow signals from pin to bench. Tells the firm’s story without text.
⎁ The Lab · v1
Where physics, silicon, and AI converge.
The PhyCircuit playground. Experiments, puzzles, and ideas that don’t belong on the main site — but earn their place by being too fun to leave on the cutting-room floor. Drag a trace. Solve a stackup. Watch heat move.
Engineers buy on substance — and they share what’s fun. The main PhyCircuit site is the resume. The Lab is the workshop, with the door open. Each artifact below is real engineering rendered as a game, a demo, or a thing you can play with.

Φ Route — BGA escape puzzle
Drag traces from a BGA pin matrix to the board edge. Three levels of increasing pin density, limited via budget. The breakout is the design — see if you can survive 0.5 mm pitch.

Φ Stack — impedance matching puzzle
Adjust the dielectric height h until every trace hits its Z0 target. Five levels from a single 50 Ω microstrip to a three-target DDR5 challenge. Real Hammerstad/Wheeler math.

Φ Thermal — cooling puzzle
Place thermal vias and copper pours to keep every component below its Tj_max. The same 2D FDM solver as Φ Thermo updates the heatmap in real time on every click.
The Lab is open. The shop is too.
When you’re done playing, the real PhyCircuit team designs production-grade PCBs. Fixed-fee quote in 60 seconds.
