Reliable PoE+ Solution for Semiconductor Inspection
INDUSTRY
Semiconductor Manufacturing – Automation – IIoT – Industry 4.0
BACKGROUND
The semiconductor industry demands ever-higher precision and efficiency in wafer inspection processes. To meet the requirements of advanced manufacturing, inspection and measurement systems must manage substantial data throughput while operating in environments with 24VDC power supplies. This creates challenges for systems requiring 48-54VDC power for PoE+ devices. These conditions necessitated a robust and innovative network solution to ensure reliable performance and seamless integration.
CHALLENGES
The customer manufactures state-of-the-art machines for the measurement and inspection of semiconductor wafers. The production process involves several complex factors:
- An ultra-precise and costly technological process demands high reliability of the hardware.
- The inspection process of semiconductor wafers requires connecting multiple cameras (5-7).
- A large amount of data is also transmitted from other system components.
Thus, the customer needed to ensure reliable data transmission in challenging conditions with the ability to connect cameras via PoE+.
SOLUTION PROVIDED
ATOP’s EHG65xx series was identified as the ideal solution to meet the customer’s requirements for reliable PoE+ functionality, with theĀ EHG6508-8PoE-24V specifically selected for its boosted PoE capability. While theĀ EH3408Ā andĀ EHG2408Ā models do not support PoE+, they offer essential managed features such as VLAN, RSTP, and QoS, making them cost-effective options for the customerās network infrastructure.
During pilot testing conducted on the customer’s premises, alongside specialists from Axtek, ATOP, and the customer, it was confirmed that the EHG65xx switches outperformed competitor solutions.
KEY STRENGTHS
- Stable performance in industrial environments
- Management features such as VLAN, QoS, and RSTP
- 8 PoE+ ports for camera connectivity
- Cost-effective
- 5-year warranty
RESULTS
The customer received a cost-effective solution to integrate sensors and cameras into a single data transmission network. The PoE+ function significantly simplified implementation and increased the overall reliability of the system.
