SEMICONDUCTOR INDUSTRY
Silicon Wafer Production: Wire Saws
Issues:
- If wire tension varies surface damage can occur
- Almost all loads are process critical
- Machines have sensitive electronic controls
- Machines use variable speed drives
Problems Arise
- Any significant voltage variation, even for a small fraction of a second, can cause malfunction of drives or controls.
- Sudden stoppages can cause loss of very costly components
- Result can be hours of downtime and substantial costs
- Significant scrap is caused - lost time cannot be recovered
- Scrap + Downtime = Loss of Profit Opportunities
Solution:
- Active Voltage Conditioner will correct voltage variations; voltage sags, voltage phase unbalance, 3 phase harmonics & voltage swells (option)
- AVC’s can be applied to groups of machines, individual machines or a complete site - available in indoor or custom outdoor enclosures.
- AVC’s available at low voltage and medium voltage to 36 kV
- AVC’s have small footprint and very high efficiency
- AVC’s can be located close to sensitive machinery
Customer Benefits
- Omniverter AVC allows processes to continue
- Costly unplanned production stoppages are reduced
- Scrap material and emergency maintenance are diminished
- Potential lost sales due to downtime are avoided
- Profits are retained
- Payback period for AVC investment typically less than 12 months
