Juki’s High-Speed Sentry Hits Triple Crown with EM Asia Innovation Award

Juki Automation Systems’ National Sales Manager Steve Nadeau commented on this accomplishment “The Sentry System is true embedded inspection in the assembly process. It allows products to be built right the first time and every time. Juki and CyberOptics are both excited to bring this new tool to the market, and we expect widening use in the years to come,”

With the introduction of Sentry, Juki has integrated the inspection process into the assembly sequence. The Sentry System was developed in cooperation with CyberOptics Corporation and is the first system to prevent incorrectly assembled boards from being reflowed. Boards are inspected at each step of the placement process with innovative sensors allowing only correctly assembled boards to enter the reflow oven.

The system does not impact the speed of the line. When/if defects are found, they are shuffled off into a buffer and the line continues to run. Additionally, the system makes no-go decisions, resulting in no false calls and dramatically increasing throughput. The result is100 percent first-pass yields.

The Sentry features innovative sensors that monitor every step of assembly. The Embedded Process Verification (EPV) Placement Monitor consists of an array of micro-cameras equipped with strobing LEDs. The cameras record five shots of each pick-and-place sequence, providing root-cause failure analysis and allowing engineers to quickly diagnose any assembly problem. The Strobing Imaging Module (SIM) quality monitor photographs boards in segments and then combines them into one image. These sensors, combined with an integrated software package, make the Sentry the most powerful tool available in PCB assembly.
