DEK recently announced that it has successfully developed a revolutionary new closed-loop innovative product called "ProDEK" and put it into commercial production. This breakthrough technology will subvert the industry's previous vision of a closed-loop printing process.
ProDEK will make its world premiere at the APEX exhibition in San Diego. This product brings a new level of dynamic printing process control, providing real-time, continuous alignment adjustment and cleaning frequency adjustment, greatly increasing production and optimizing yield. At the same time, reduce manual operator intervention as much as possible.
"In simple terms, ProDEK will make your printing press more intelligent and intuitive," said Brian Smith, general manager of DEK Electronics Assembly in the Americas. "ProDEK is built on unique printing software performance and solder paste inspection (SPI ) The data collaborates together, using high-level process parameters to precisely control the printing alignment and cleaning functions. This is currently the most powerful and repeatable 'automated' printing technology. "
Using the solder paste deviation (calibration) data transmitted from the SPI system to the printing machine, ProDEK monitors a configurable number of printed circuit boards and then sends independently corrected forward and backward offsets to the printing machine, after which it is adjusted in real time Position of solder paste on the pad. Using barcode tracking technology, ProDEK can ensure the synchronization of printed and inspected circuit boards.
In addition to real-time, continuous alignment without additional management costs for the printing / inspection process, ProDEK also monitors the number of high zone warnings in the SPI data, which may be a sign of excessive or insufficient cleaning of the bottom of the screen. This innovative technology can automatically adjust the cleaning frequency to adapt to the current process conditions, optimize the cleaning process at the bottom of the stencil, and thereby significantly reduce the use of consumables while bringing better process stability. ProDEK can be installed on all DEK's new printing platforms, or it can be installed on-site on the installed DEK system. It is currently compatible with industry-leading SPI technologies such as CyberOptics, Koh Young and Parmi.
ProDEK has proven to have a positive effect on preventing defects, optimizing printing performance and ensuring the highest through rate. ProDEK has conducted field tests in many major electronic assembly manufacturers. The data shows that the deviation correction function alone can reduce the defect rate by about 50% on average.
Brain Smith concluded: "The real value of ProDEK lies in the process technology expertise and decision-making functions integrated into the software: this is an automated knowledge base that brings unprecedented process control."
