VAHLE Commissions OHT Test Facility for Research and Development
Expanding research and development capabilities in the semiconductor market through a realistic test environment for contactless power transfer systems. The focus is on performance, efficiency, and system stability.
VAHLE has commissioned a new development and testing facility for Overhead Hoist Transport (OHT) systems at its Schwoich site. The facility is part of the company’s research and development strategy for the semiconductor market and serves as an internal platform for designing, testing, and validating solutions for contactless power transmission.
“With the OHT test facility, we are creating a central foundation for further developing our technologies specifically to meet the requirements of the semiconductor industry,” says Marc Detweiler, Director of Product Management and Marketing at VAHLE. “It enables us to test new systems under realistic conditions and continuously optimize them.”
OHT systems are used in the semiconductor industry for automated, ceiling-guided material transport. The transport systems move on rails beneath the factory ceiling and autonomously transport the containers, known as FOUPs (Front Opening Unified Pods), or magazines from one process station to the next.
Among other things, they handle the transport of wafers—thin silicon discs on which microchips are manufactured. These are moved through production protected within the FOUPs. OHT systems also ensure a continuous material flow in the field of so-called integrated circuit (IC) packaging, i.e., the further processing and packaging of the chips.
The demands on these systems are high: in addition to maximum availability, cleanroom compatibility, dynamics, and operational reliability play a central role. “With the new test infrastructure in Schwoich, we are creating a realistic development environment in which new product generations can be tested under practical conditions,” explains Detweiler.
This includes, among other things, stress tests under defined acceleration and load profiles, as well as the validation of contactless power transfer during continuous operation. Furthermore, the facility enables detailed analyses of the interplay between dynamics, power transfer, and the thermal behavior of the systems.
A key advantage of the test environment lies in the ability to conduct development and optimization processes entirely in-house. “This allows new technologies to be tested and further developed independently of existing customer systems,” says Detweiler. At the same time, the development time for new solutions is reduced, as tests can be conducted flexibly and reproducibly.
Against the backdrop of growing complexity in semiconductor manufacturing, high-performance and stable transport solutions are becoming increasingly important. The continuous advancement of the underlying technologies is crucial to ensuring process reliability and efficiency throughout the entire value chain.
With the commissioning of the OHT test facility, VAHLE is strengthening its position as a development partner in the field of automated material flow systems for the semiconductor industry. The facility forms the foundation for future product developments and supports the company in addressing rising demands for performance and reliability in the OHT environment.
