e/Fixtureless in-circuit test

Information
has gloss	eng: Fixtureless in-circuit test (FICT) is a cost-effective alternative to a "bed of nails" tester for in-circuit testing of low to medium volumes of printed circuit board assemblies. It relies on a computerized optical inspection of the circuit assembly and positionable test probes. Traditional "bed of nails" testers require the manufacture of a complex mechanical fixture comprising pins inserted into holes in an acrylic plate connected to the measuring unit by wires. Some of the disadvantages of the bed of nails tester is the number of wires used will often increase the capacitance of the circuit so that values below 60 pF are difficult to measure accurately. Also, the holes in the plate do not allow pins to be placed close enough together to test fine pitch components with a lead pitch of 0.5 mm unless test pads or vias allow connection from another part of the circuit.
