PCB Test & Diagnosis

    Every board tested, diagnosed and sorted by a Cobot

    The Cobot loads each board onto your tester, adds a camera check for visible faults, and hands your technician one clear fault report. The same steps as a person doing it by hand, just faster and the same every time.

    How the cell works

    Four steps per board, running without breaks.

    The Cobot takes each board from the rack by its edges and seats it on the test fixture.
    01 · Load

    The Cobot takes each board from the rack by its edges and seats it on the test fixture.

    A connected tester, run by a computer, checks power-on, voltages and currents, boundary-scan and firmware.
    02 · Test

    A connected tester, run by a computer, checks power-on, voltages and currents, boundary-scan and firmware.

    Once the arm has settled, a camera checks for visible faults: solder bridges, missing, tilted or reversed parts, cold joints, burn marks.
    03 · Inspect

    Once the arm has settled, a camera checks for visible faults: solder bridges, missing, tilted or reversed parts, cold joints, burn marks.

    Tester results and the image are combined into one fault report with the likely location. The board goes to the pass or fail tray.
    04 · Report & sort

    Tester results and the image are combined into one fault report with the likely location. The board goes to the pass or fail tray.

    What the cell checks

    Visible faults (camera)

    • Solder bridges and cold joints
    • Missing, tilted or reversed parts
    • Burn marks and damaged areas
    • Wrong or misplaced components

    Electrical faults (tester)

    • Power-on and short checks
    • Voltage and current out of range
    • Boundary-scan (JTAG) failures
    • Firmware load and self-test results

    What we don't claim

    • No 100% promise. Coverage depends on the fixture and test program for each board, and we state it per project.
    • Engineers stay in charge. The cell does the repetitive testing and diagnosis. Your technician does the repair.
    • Soldering by Cobot is on request only, after a separate safety review.

    Your technician only does the repair

    Each failed board arrives with a report: which test failed, the camera image and the likely location. No more hunting for the fault. Skilled people spend their time fixing boards instead of testing them.
