Flying Probe Test (FPT)

The flying probe test also called “Fixtureless Testing” on the other hand do not have a bed of nails fixture except it has a fixture to simply hold the bare or assembled PCB board. The PCB is moved on the conveyer belt and brought directly under the robotic architecture of flying mechanism of testing system. The flying probe test (FPT) is basically the system of automated robotic hands that can move in x, y coordinates to gain access to each and every point on entire PCB and use z axis to move the probe vertically towards and away from the PCB. The robotic arm end effector is actually the probe that is connected to the back end testing system. The testing system is pre-programmed to carry out different measurements like voltage, current measurement, and impedance measurement, components value like resistance, capacitance and inductance. The component orientation and component polarity detection is done by a high definition camera installed on the PCB flying probe setup.
