Power Supply in Semiconductor and Display Production

8 June 2022

Precision Decides

Hyundai, Daewoo, Samsung, LG, SK Hynix – many South Korean companies are global players. In addition to shipbuilding and automotive engineering, South Korea's electronics and semiconductor industries are among the world's leaders. Especially in semiconductor memory and display production, this leadership can only be maintained through maximum efficiency and precise production. This is why major South Korean manufacturers and suppliers increasingly rely on the WAGO Power Supply Pro 2.

Innovations such as “Processing in Memory,” i.e., the integration of dynamic memory (DRAM) and processor, or quantum light-emitting diodes (QLEDs) originate from South Korea. They excite experts and delight users. The industry's general mantra – higher power density, higher speed and lower power consumption – can only be achieved by perfecting manufacturing. Semiconductor memory or QLED fabrication has reached the nanometer range; such advanced technology makes ever more complex manufacturing processes and increasingly complex machines necessary.

Machines with the Highest Requirements

“Machines for semiconductor memory or display production are not only very large but extremely sensitive,” explains Haeyong Kim, Sales Manager at WAGO Korea. “If a sensor or motor is not supplied with an exact voltage, product quality suffers and the complexity of the production machine makes troubleshooting enormously complex.” Therefore, it is hardly surprising that the DC switched-mode power supplies are held to the highest requirements. However, classic 24 V power supplies cannot withstand this because they lack essential functionalities.

Communication over Everything

“Our high-tech customers in South Korea have very quickly recognized the potential that lies in the communication properties of the WAGO Power Supply Pro 2,” explains Kim. “The advantages that result from their use aren't instantly obvious. Upon second glance, several more advantages appear and prove to be very useful for the customer. A power supply, which provides information in the millisecond range about current strengths, output voltages, overload behavior, etc., won't be stopped when it comes to detecting, localizing and even preventing faults.” Through a snap-on type communication module, the Pro 2 Power Supply can establish permanent fieldbus communication for sending status data to a higher-level controller. Thus, each 24 V cable has extensive monitoring capabilities, and the abnormalities of connected loads are immediately recognized and visualized.
