Method and apparatus for testing printed circuit boards
A method for testing printed circuit boards (20) in a test apparatus having a carrying apparatus for the printed circuit board (20) and having test modules for measuring physical variables of components (EB) and contact points (29) on the printed circuit board (20), in which the width of the printed circuit board (20) defines an X direction, its length defines a Y direction and its thickness defines a Z direction inside the test apparatus, reference points, the X, Y and Z positions of which relative to the carrying apparatus are known, are present on the printed circuit board (20) or outside the latter, the X and Y positions of the components (EB) and contact points (29) relative to the reference points are known, the measurement of the physical variables depends on an actual Z position of the printed circuit board at the X and Y positions of the component (EB) or contact point (29) to be measured, and the actual Z position of the printed circuit board at the X and Y positions of the component (EB) or contact point (29) to be measured is determined by means of an interpolation method starting from the X, Y and Z positions of selected reference points.
Capacitive opens testing of low profile components
A probe assembly for capacitive testing electrical connections of a low profile component to a circuit assembly. The probe assembly is configured to reduce coupling of noise signals from the circuit assembly to the capacitive probe. The probe assembly includes a sensing member with a geometry that allows the probe to preferentially couple to test signals from the pins of a component under test rather than conductive structures on the circuit assembly, such as pads, and signal traces to which those pins are attached. The sensing member may be a vertical capacitive sense plate such that coupling is to an edge of the plate. The sensing member alternatively may be a horizontal capacitive sense plate with an active area of the probe surrounded by an isolation ring. Measurements made with such capacitive probes may provide test measurements that yield a reliable discrimination between a properly attached pin and an open pin.
TESTING DEVICE
A testing device for testing an electronic device includes a base, a testing mechanism, a pushing mechanism, and a fastening mechanism. The testing mechanism is rotatably fastened to the base and can be rotated from a first position to a second position. The fastening mechanism is mounted on the base. The pushing mechanism is rotatably mounted on the testing mechanism. When the testing mechanism is rotated from the first position to the second position, the pushing mechanism is rotated and pushes against the testing mechanism. The testing mechanism is connected to an electronic device. The testing mechanism is positioned in the second position via the fastening mechanism.
