We test the boards with flying probe or fixture tool, both the cost are estimated. Flying probe will be calculated based on the quantity of test points, and fixture test will be based on the fixture tool cost. We suggest to use the fixture if the boards is more than 3sqm, because it will be save a lot of time.
