For Release April 11, 2011Press and Reader Information Contact:André MynyErica CandelaKoh Young TechnologySpeedline Technologies, Inc.Tel: +31 650853144 Tel: +1‐508‐541‐4749Mail to: andre.myny@kohyoung.comMail to: ecandela@speedlinetech.comKoh Young, MPM/Speedline ‘Close the Loop’ <strong>with</strong> <strong>SPI</strong> <strong>Print</strong> <strong>Optimizer</strong><strong>Innovation</strong>Koh Young Technology and MPM, a division of Speedline Technologies, Inc., announce the codevelopmentof a closed‐loop communications link between the MPM printer and a Koh Young SolderPaste Inspection (<strong>SPI</strong>) system that allows the two to automatically work together to optimize the solderpaste printing process.The product of this developmental partnership, the<strong>SPI</strong> <strong>Print</strong> <strong>Optimizer</strong>, brings the inspection systemand the printer together to not only identify defects(<strong>SPI</strong> system) but correct them (MPM printer). Thisprevents soldering defects downstream that resultin excess rework, productivity delays, and loweryields. The innovative product is the result of aclose collaboration between <strong>SPI</strong> and AOI inspectionleader Koh Young and global automated printingtechnology leader MPM/Speedline, workingtogether to build a better PCB assembly process<strong>with</strong> fewer defects and higher quality and is the firstof its kind.Based on the measurements of the <strong>SPI</strong> system (after the print) communicated to the printer, the printersoftware automatically adjusts printing parameters to optimize the print process and mitigate the solderproblem that could result in defects. The <strong>SPI</strong> <strong>Print</strong> <strong>Optimizer</strong> works <strong>with</strong> all current MPM printers and KY<strong>SPI</strong> machines.Studies have shown that the majority of circuit assembly defects begin at the paste printing step. Byoptimizing and managing solder paste printing effectively, a customer can prevent costly defects,rework, and delays downstream. The <strong>SPI</strong> <strong>Print</strong> <strong>Optimizer</strong> establishes a closed‐loop communicationbetween the inspection system and the screen printer. It allows the process engineer to monitor andimprove the entire print process, rather than just a single parameter of the process.
In operation, <strong>SPI</strong> print offset measurements are sent directly to the printer for on‐the‐fly alignmentcorrection. Rejected boards from the <strong>SPI</strong> machine can trigger a pre‐programmed under‐stencil cleaningwipe action.The <strong>SPI</strong> <strong>Print</strong> <strong>Optimizer</strong> compensates for uncontrollable or difficult to control process variables, andachieves the desired print registration <strong>with</strong>out manual process “tweaking”. It either eliminates orreduces operator intervention and errors, and stabilizes the print process.The <strong>SPI</strong> <strong>Print</strong> <strong>Optimizer</strong> is a powerful process optimization tool that is especially critical for lead‐free andminiature component attachment, where solder paste volume control is extremely important, and canbe used for process setup and fine tuning. Its overall contribution to PCB assembly is fewer solderingdefects, higher yields, less operator intervention, improved product reliability and improved overallprofitability.About Koh Young TechnologyKoh Young Technology, a leading provider of Solder Paste Inspection (<strong>SPI</strong>) and Automated OpticalInspection (AOI) systems, specializes in the design and manufacturing of 3D measurement andinspection equipment for the global circuit board assembly and semiconductor markets.
