DEK print inspection system selected by Multi-Tech

For today's electronics production, process speed is at the heart of it. To date, maintaining the beat rate of the production line means giving up full testing. Recently, the DEK HawkEye post-print inspection system was selected by Multi-Tech, a manufacturer of networking products, to meet the speed requirements of one of the advanced assembly lines.

Del Palacheck, Multi-Tech's vice president of manufacturing, said: "We hope to conduct a 100% inspection of all boards on this production line without affecting production speed. Testing 3,500 components per day is a very high requirement. HawkEye allows us to maintain the beat of the original production line and at the same time achieve 100% post-print inspection."

According to reports, the products manufactured on Multi-Tech's Horizon 01i + HawkEye 1200 line are embedded modems for advanced remote control systems such as multi-function printers/fax/copiers, point-of-sale terminals, cash registers, and cashier systems. . For 3,500 components produced daily, the board is produced in three separate components and grouped in different numbers. Due to the different number of each component, Multi-Tech requires inspection of all component mounting surfaces to ensure the highest end-of-line yield.

The Multi-Tech product line has a good one-pass yield, and it also provides its assistive tool system to achieve nearly one-hundred percent pass yields. Unlike conventional inspection systems that use data-rich quantification programs and continuous still image analysis, HawkEye incorporates a new inspection method that quickly scans the board as a continuous stripe and collects a set of strictly defined monochrome image data. This data is then compared with a user-defined preset acceptance limit, and HawkEye then determines if the board can proceed to the next process step. The system is highly flexible, allowing the user to inspect all printed applications on the board, as well as inspecting only part of the board, allowing the manufacturer to adjust the overall inspection time and obtain it without sacrificing the speed of the production line. Maximum production system value.

While evaluating and selecting the HawkEye system, although speed is a major consideration of Multi-Tech, ease of use is also a great advantage of this technology. Rick Oelkers, Multi-Tech Automation Director, commented: “The system is extremely simple to install and operate, requires minimal programming and is easy to use. Now we can easily inspect every board that passes through the machine without affecting it. Production speed."

There are two configurations of the HawkEye system to accommodate different production speed requirements. The HawkEye 400 verifies the printed coating at 400 square millimeters per second, while the HawkEye 1200 has a speed of 1200 square millimeters per second. In contrast, the traditional two-dimensional inspection method can only test standard SMT components at an average speed of 28 square millimeters per second.
