Seica Launches New Flying Probe
Flying probe bare board tester.
Salem, NH — Seica SpA has added to its new generation of flying probe test systems with the introduction of the S280 — a horizontal flying probe test system designed specifically for testing any type of printed circuit board from simple single-side circuits, to complex multi-layers, inner-layers and ceramics. The system is equipped with 8 completely independent mobile probes, four probes on each side of the board.

The prober has been equipped with a new pass-through conveyor and MBTH (multi-type-board-handler), enabling operator-free operation to satisfy any high production volume. Up to 100 different PCBs can be loaded and tested fully automatically.

Third-generation linear guide means that the system can achieve very high speed with the maximum accuracy and measurement repeatability; the X and Y axes utilize roller bearings and powerful brushless motors coupled with pre-loaded, high precision ball screws to move the eight measurement probes. The integrated ultra-compact linear motors enable high speed performance and absolute touchdown control. The integrated pneumatic board handler is able to automatically "stretch" to handle large panels as well as thin PCBs, using motorized width adjustment which automatically moves the fixture to the programmed position.

The flying prober is equipped with a new generation of probes; the innovative design, in combination with the capability to move each test head independently and position 8 probes on the same pad (4 on each side) allows the execution of both Kelvin Test and Barrel Tests without changing probes. It is also possible to test any type of embedded component; with the relative options enabled, the Viva software will automatically generate the Kelvin test, Barrel test and ICT test for these types of components.

The high level of programmability and run-time control of the Z-axes allow the user to program the speed and pressure of every test probe, leaving virtually no marks on the PCB. The software also allows the user to "autolearn" the non-planarity of the board under test, then to compensate and perform an X-Y-Z retry to verify immediately any fault that had been detected. Five different profiles are available at the operator level to automatically manage all kinds of PCB surfaces.

The standard configuration the S280 comes with a complete vision system which includes two CCD cameras, one for each side of the PCB. The cameras can be used for: recognition of fiducials for automatic centering of the board under test; verification/modification of test points; optical inspection of part on the board under test; learn test points for unknown PCBs in order to recreate the netlist; live probes view, making it possible to view the probes contacting the PCB.
