Import Tips
• Document RF heating as nonelectric process to distinguish from electric furnaces; include material compatibility certifications for silicon/gallium arsenide
• Beware of reclassification if furnace diameter exceeds statistical notes for wafer prep equipment
• Ensure INA bonding compliance for high-value semiconductor tools
