Summary:This invention relates generally to the field of testing electronic circuit boards. More particularly, this invention relates to a method and apparatus especially useful for coupon testing low value components on electronic circuit boards. A circuit board coupon testing method and apparatus. A coupon tester uses a linear actuator to carry a test head and probe(s) for an LCR meter. The linear actuator accurately steps the probe(s) over a coupon of components arranged linearly adjacent an edge of the circuit board to measure the parameters of the component. The coupon tester can be integrated with an in-circuit tester to provide further functionality, with the coupon test being carried out simultaneously with a portion of the in-circuit test such as an unpowered portion of the in-circuit test.
