CmController5 Compact reportedly helps improve yields and reduce solder joint defects by improving solder paste printing machine process stability. Solder paste printing is a critical step in the SMT PCB assembly process, since 60 to 70% of all soldering defects can be traced to the printing process.  The controller provides measurement technology for equipment and process capability analysis for printers and other production equipment; the data and measurement results obtained provide the base for stable and controlled printing and processing.
 
Michael Sivigny, general manager, said, "When a consistency problem originates in a systematic deviation, data from testing with our CmController is used to identify offsets, calibrate the printer and restore stability and repeatability to the printing process, lowering defect levels, eliminating rework and increasing throughput and profitability."
 
Process capability for a solder paste printer is measured by printing glue dots or solder paste on a highly accurate glass board with a specifically-matched laser-cut stencil and then evaluating it in the controller, particularly the positioning accuracy of the printed solder deposition relative to the substrate structures.

The mobile product and service offers third-party, objective evaluation methodology. Special vision algorithms, accurate glass plates and components allow for independent measurement of Cp and Cpk indices on production equipment. All brands and models of SMT printers, dispensers, placement and semiconductor machines are validated. Is designed for use on the production floor, does not require a controlled cleanroom environment.
