Flexibility of test and handling of different PCB grids with one common electronic module are the achievement marks of the ATG EXAline MD grid tester. It combines manual and automated testing at a throughput of up to 1000 boards per hour. The EXAline can be set up within minutes and it offers user-friendly operation: the test area is open and accessible, with a rotated top-side fixture. The probe location is displayed. The probe can be replaced with the fixture left in place. Marking is feasible with label or ink-jet prin-ter. The paternoster feeder en-ables non-stop operation. Alignment is either optical or electrical, with no reduction in through-put and precise recognition and compensation shift. Minimum testable pitch is 10-mil. Contact pressure can be 10,000kg, evenly distributed. The system offers an upgrade option for MD4 probes, with a test point density of 1.27mm.
