Using this software, for example, not only is the actual AOI fault image displayed, but also the respec- tive angled-view images from a horizontal angle of 45° or 90°, comparison images of a good PCB, or the 3D view of the PCB or solder joint. If further inspection systems (SPI or AXI) are integrated into the production process, these re- sults, measurements and images are also avail- able for assessment. Moreover, SPI, AXI and AOI systems from other manufacturers that are already integrat- ed into the production line can also be integrat- ed via the PILOT Connect software module, en- abling their results to be presented at the verifi- cation station. Central Verification for Numerous Production Lines These opportunities shown make it possi- ble to competently assess the detected errors re- motely. But how does the technical implemen- tation for central verification take place in a production with numerous inspection systems or numerous lines? A simple solution would be the remote control of existing inline verification stations (e.g., via a remote desktop connection). However, the entire equipment of such a work- station at the respective position in the produc- tion line would be required for this, made up of a PC, interface card to the belt module as well as software licences. Both costs and required space for the inline workstation are impacted here. With a system such as Goepel's PILOT Su- pervisor, the transfer of the classification re- sult (PASS or FAIL) to the line (e.g., for sorting the PCB into the corresponding hopper), takes place via ethernet communication—either di- rectly with the belt module or via a conversion into potential-free outputs. This ensures the verification of inspected PCBs (by AOI, AXI or SPI) is possible both for numerous lines and for various systems from a central station. In the age of globalization and worldwide networking, this can even be done from a remote company location. Apart from the central verification of inspec- tion results, the system also enables operators to see these inspection systems in a schemat- ic diagram in their respective production lines, as well as the currently tested PCB. A display of the pending data sets is also available for ver- Figure 2: Verification station software PILOT Verify with AOI and AXI fault images.
