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.

The DFP2-LS is paired with an SMT production version of Akrometrix Studio software which includes the Surface Measurement, Part Tracking and Real Time Analysis capabilities which can set pass/fail parameters, capture data for every PCB assembly tested and store the entire library of units tested, all set by the system operator.

Surface Measurement: (Measurement Setup)

• Work from a live system view to setup multiple test parameters
• Run multiple displacement image and 3D measurement results windows concurrently
• View displacement graphs and data when data is acquired
• Work with multiple regions of interest
• Includes Part Tracking feature and Real Time Analysis (RTA) software
