Soldering inspection device ViComp

quality

The optical inspection unit ViComp supports operators during the test and repair work. Manual and automatic inspection methods allow an fast and easy setup of test programs for different sizes of batches. For small batches and prototyping programming can be done fast and easily by image comparison with a Golden Board. A manual and an automatic mode are available. In the manual mode alternating images of the golden board and the production board are shown on the monitor. The differences between the images (defects) will be recognised by the operator at once, as the human eye is trained to recognise fast changes. In the automatic mode the areas to be tested have to be predeter- mined. When using a bare board or a printed board, these test areas are created automatically. All of these test areas are later compar- ed with the Golden Board. A report will be generated during the test. If a Golden Board is not available, a normal production board can be used, with all the variations in process quality. These boards are not perfect references, but the programming is fast and easy. If the batch size is bigger or a higher level of test depth and a lower quantity of pseudo defects are required, the programming with CAD-data is advised. The compre- hensive component library and a user friendly menue simplifies programming. The component library provides all parameters which can be modified by the operator
