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 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.
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.
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.

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.
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.
