ProDEK closed-loop printing technology enhances dynamic control standards

DEK recently announced the successful development of a revolutionary new closed-loop innovation called "ProDEK" and commercial production. This breakthrough technology will disrupt the industry's previous idea of ​​closed-loop printing process.

ProDEK will be the world premiere at the APEX exhibition in San Diego. This product brings a new level of dynamic printing process control, provides real-time, continuous alignment adjustment and cleaning frequency adjustment, greatly increase production, optimize yield, At the same time as much as possible to reduce operator manual intervention.

“In short, ProDEK will make your presses smarter and more intuitive,” said Brian Smith, general manager of DEK's Electronics Assembly Division in the Americas. “ProDEK builds on unique print software capabilities and solder paste inspections (SPI ) The data collaborates together, using high-level process parameters to precisely control print alignment and cleaning functions. This is the most powerful and repeatable 'automated' printing technology available today."

Using solder paste deviation (calibration) data transmitted from the SPI system to the press, ProDEK monitors a configurable number of printed circuit boards and then transmits independently corrected forward and backward offsets to the press, which is then adjusted in real time The positioning of the solder paste on the pad. Using barcode tracking technology, ProDEK ensures the synchronization of printed and verified boards.

In addition to real-time, continuous alignment calibration that does not result in additional management costs for the printing/inspection process, ProDEK also monitors the high zone warnings in the SPI data, which may be a sign of over- or under-cleaning at the bottom of the screen. This innovative technology can automatically adjust the frequency of cleaning to suit the current process conditions and optimize the cleaning process at the bottom of the stencil, thereby further reducing the use of consumables while providing better process stability. ProDEK can be installed on all of DEK's new printing platforms and can be installed on-site on installed DEK systems. It is now 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 at many major electronics assembly companies. The data shows that the error correction alone function can reduce the defect rate by an average of 50%.

Brain Smith concludes: "The true value of ProDEK lies in the integration of process technology expertise and decision-making capabilities in software: this is an automated knowledge base that brings unprecedented process control."
