Characteristics of the Pick And Place system• Functions and Operation• Machine’s performances• Components of the system? Management SWMeridionale ImpiantiSmart Solutions for Innovative CompaniesThis automatic tool is a production unit to sort and pack solarcell dies, based on III-V compound semiconductors grown byepitaxy on 4-inch Germanium wafers.ScopeWafer that containsabout 60 solar cellsMeridionale ImpiantiSmart Solutions for Innovative CompaniesFunctions and OperationThe pick and place tool is able to:? Read and elaborate files that contains the measurementdata of the wafer to be sorted out:Voc - Isc - Mpp - Eff - FF - Vmpp? Link each solar cell listed in the wafer measurements fileto position inside the wafer and identify the correspondingbinning class to the operator’s instructions.Meridionale ImpiantiSmart Solutions for Innovative Companies? Pick up the solar cell from the pre-cut wafer. The waferis mounted on a very sticky foil sheet.? Place the solar cell in the tray corresponding to theappropriate binning class. The machine is able tosimultaneously handle a set of 10 trays corresponding to10 different binning class.? Print on each tray an appropriate code (barecode +alphanumeric) identifying the production batch andrelevant binning class.Functions and OperationMeridionale ImpiantiSmart Solutions for Innovative CompaniesMachine’s PerformancesThe machine’s performances are customizable according to production needs, in particular:? Cell’s dimensions: the machine is able to process solarcells of different size (3mm x 3mm; 5mm x 5mm; 7mm x7mm; 10mm x10mm; etc. )? Adhesive force of foil sheet? Number of wafer to process each hourMeridionale ImpiantiSmart Solutions for Innovative CompaniesMachine’s Performances? The code on cell’s boxes is customizable to accordingoperator’s instructions (barecode, alphanumeric; size;thickness; etc.).? Vision system is able to do a visual inspection of thewafer quality and can detect the effective picking of thecell during process.Meridionale ImpiantiSmart Solutions for Innovative CompaniesComponents of the System– Robot:Five axis, high speed robot suitablein the following areas: order andpicking, packing and palletizing.– Vision System:To calculate the center position ofthe wafer, correct orientation errorsand visual inspection for cellsquality.Meridionale ImpiantiSmart Solutions for Innovative CompaniesComponents of the System– Automatic printer:To print in each cell box a code toindentify the production batch andrelevant class properties.– Biaxial System:To facilitate cell picking from stickyfoil sheet.Meridionale ImpiantiSmart Solutions for Innovative CompaniesManagement SoftwareMain PageA S.C.A.D.A. system (Supervision Control and DataAcquisition) permit the interaction between machine andoperators to set parameters and control the state of theprocess.Meridionale ImpiantiSmart Solutions for Innovative CompaniesManagement SoftwareSetting page to insert the parameters process:- Filter parameter and Classes range-Wafer and baredie characteristicsSetting PageMeridionale ImpiantiSmart Solutions for Innovative CompaniesManagement SoftwarePrinter Setting page to insert the codes to print on cellboxes, a typical code is :N° Wafer - Epitaxial Run – Class – N° boxEg: W1 – 2495 – 03 - 01Printer SettingPageMeridionale ImpiantiSmart Solutions for Innovative CompaniesManagement SoftwareMeasurements page shows the wafer’s geometry andelectrical measurements for each solar cell.MeasurementsPageMeridionale ImpiantiSmart Solutions for Innovative CompaniesManagement SoftwareControl page to monitor the state of the machine andsend commands.
