The days of measuring coplanarity with mechanical shim gauges at a few select points are gone. With the DFP2-LS End-of-Line Warpage system (DFP2-LS), coplanarity is measured across the entire surface of a fully populated PCB assembly after the post-reflow process. Utilizing Akrometrix newly released Digital Fringe Projection (DFP2) vision system, any Akrometrix Metrology System with this technology is capable of measuring a discontinuous surface with varying step heights over the entire field of view of the system. In the case of the DFP2-LS, the D.U.T can be a PCB as large as 585mm x 468mm, where the entire surface is measured in a matter of seconds, not minutes.
