Sigmaprint AX400•Auto Programmable•Powered Stencil Load/Unload•Integrated Vision Robotics•Selective Alignment Strategy•High Resolution CCD ImageJanuary 20th 2009EC's Commercial Director, Bill Green comments:' We are always striving to improve our efficiencies by improving yields through investing in the latest technology for our business.'In the summer of 2008 we upgraded our surface mount line with the installation of Philips/Assembleon equipment. This new line supports our developing business strategy, which is to provide a fast turn round service from our UK operation, focusing on batch sizes of 50 -500 off.In order to improve the reliability and accuracy of the in-line screen printing process, we installed a fully automatic Sigmaprint AX400 at the beginning of 2009.We believe the addition of the Sigmaprint AX400 to our surface mount line, will further enhance our ability to attract new clients, as well as provide an upgraded service to existing customers.'Power assisted loading of the stencil reduces the risk of damage, speeds setup and assists accuracy and repeatability.Multi-point alignment compensates for stencil stretch or positional variations.Dynamic software supports alternative alignment strategies, delivering ultra-fine capability for every application.Board/stencil alignment depends on the quality of the CCD images.The IVR system of the Sigmaprint 400 uses a high resolution image (512 x 512 pixels) to give excellent definition and precision alignment for perfect print quality. Integrated Vision Roboticsuses (IVR) uses a singleroving camera with dualplane optics, giving perfectboard stencil alignmentevery time.IVR is flexible and can be tailored exactly to production needs.Alignment can usededicated fiducials withadvanced precisionsoftware achieving highprecision registration.Features of IVR includeinclude image recognition,vision systems training andalignment calibration.Tooling setup, conveyor width adjustment and board stop position are all programmable. The IVR head automatically selects and positions posts posts accurately for optimum support during printing.Tooling posts can be placed anywhere within the print area to avoid underside components or support critical areas of the board.Automatic setup procedures require no manual intervention, reducing the risk of operator errors and significantly increasing overall productivity.The tooling software eliminates the possibility of board damage and production errors by precision management of tooling throughout the configuration process.
