70%+ of defects set at the front
Paste volume, area ratio, registration, and sub-25µm placement offsets decide the board's fate before reflow.
Physical AI for electronics manufacturing
Every board, perfectly built.
Circuex is the autonomous operations layer for PCBA lines — a closed loop of physical-AI agents that print, solder, inspect, simulate, orchestrate, and handle every board, so first-pass yield converges by itself.

The problem
The craft is retiring faster than the boards are shipping
Solder-paste volume, reflow profiles, and inspection thresholds are still tuned by hand by scarce process engineers — and the drift is invisible until the field finds it.
Reflow is a black art
Hand-built thermal profiles are frozen, then drift as boards densify and mix changes — tombstones and hidden BGA voids follow.
Inspection floods false calls
Rule-based AOI/AXI throws 5–20x false calls while genuine escapes still reach the field.
The expertise is leaving
The engineers who can shortcut NPI and rescue a line are retiring, and high-mix multiplies the tuning burden.
The platform
One closed loop, six physical-AI agents
Perceive → simulate → decide → act. Each agent owns a stage of the line and writes every condition, recommendation, action, and result to a shared closed-loop corpus.

Physical Actuation
Graduated autonomy throughout — human-in-the-loop checkpoints, approval policies, and an assurance-grade audit trail.
Proof, not promises
The line optimizes itself, and shows its work
Circuex closes the loop from perception to action and back — every move validated in the twin, every call grounded and logged.
- Real-time perception of SPI, AOI, AXI, coating, and oven telemetry at the edge.
- Predictive control that tunes print, placement, and reflow before boards fail.
- Closed-loop feedback from inspection and test back to the front of the line.

Who runs Circuex
For the people who own the line
Plant & operations
Real-time first-pass yield, false-call rate, and rework visibility — line-level optimization under approval policies.
Process & NPI engineers
Qualify recipes in the twin before the run; let the agents carry the tuning load across high-mix changeovers.
Quality & reliability
Grounded, cited inspection calls and an assurance-grade audit trail for automotive, medical, and aerospace.
We stopped firefighting the front of the line. Circuex catches drift before a single board fails — and it tells us exactly why.
How teams adopt it
From one stage to the whole loop
01
Connect
Read-only connectors to printer, SPI, mounter, oven, AOI/AXI, and MES — no rip-and-replace.
02
Observe
Agents perceive and predict in shadow mode; you see grounded calls without any write-back.
03
Assist
Graduated autonomy turns on recommendations, then approvals, then closed-loop control per stage.
04
Scale
Add agents across the loop and roll the qualified recipes to every line and site.
Every board, perfectly built.
