Q1: Can you produce custom dimensions or shapes?
A1: Yes. We offer target diameters from 50–200 mm, thicknesses from 3–10 mm, and optional Cu/Ag bonding.
Q2: What’s the expected service life of a samarium planar target?
A2: With proper sputtering conditions, our fine-grain (<50 µm) targets achieve over 85% utilization under standard DC/RF sputtering.
Q3: How should the targets be stored and handled?
A3: Store in a dry, inert gas (argon/nitrogen) atmosphere. Use gloves to avoid contamination. Pre-sputter cleaning is recommended.
