This sputtering target requires bonding to a backing plate and vacuum packaging to maintain surface integrity. Dimensional tolerances of ±0.10 mm and surface roughness below 1.6 µm must be respected for proper fit and sputtering performance.
- Bonding Requirement: The target is supplied unbonded and must be bonded to a compatible backing plate before use in a sputtering system.
- Surface Condition Preservation: Vacuum packaging preserves the as-machined surface; handle with clean gloves and avoid exposure to airborne contaminants.
- Dimensional Tolerances: The diameter and thickness tolerances of ±0.10 mm ensure compatibility with standard sputtering gun receptacles.
- Packaging and Storage: Store in the original vacuum packaging until ready for use to prevent oxidation and maintain purity.
What purity, density, and electrical resistivity are specified for the Atomfair 99.99% chromium sputtering target?
The target is specified at 99.99% purity (Cr 3N5 grade) with typical total critical impurities of <=100 ppm, a density of 7.19 g/cm3, and an electrical resistivity of 12.9 micro-ohm cm. These are the controlled material parameters cited for magnetron sputtering and related thin-film applications, with final parameters confirmed by batch inspection and reported on the COA.
Is this chromium target supplied bonded or unbonded, and what must be confirmed for sputtering system compatibility?
The target is supplied unbonded as standard, with optional Cu backing plate bonding available. Because bonding configuration affects compatibility with sputtering equipment, the model, working range, consumables, and required configuration must be confirmed before quotation; include the required model, configuration, and quantity in your inquiry.
What surface finish and dimensional tolerances should be verified before installing this chromium target?
The target surface is turned or ground with Ra <= 1.6 um (typical), and dimensional tolerance is diameter +/-0.10 mm and thickness +/-0.10 mm (typical). Final parameters are confirmed by batch inspection against the agreed configuration, and the target is vacuum packed with a COA.
High purity chromium sputtering target (99.99%, 7.19 g/cm³ density, 12.9 µΩ·cm resistivity) offering controlled impurity levels ≤100 ppm for decorative coatings, wear-resistant films, and barrier layers. Available in unbonded round planar geometry with multiple thickness and diameter options, but requires configuration review for bonding and dimensional tolerance.
Positive
- High purity with controlled impurities: 99.99% purity grade with typical total critical impurities ≤100 ppm ensures reproducible film properties and reduced contamination in sensitive sputtering processes.
- Multiple diameter and thickness options: Available in 8 diameters (25.4–101.6 mm) and 5 thicknesses (3–6.35 mm) enables direct integration into diverse magnetron sputtering systems without custom machining.
Trade-offs
- Unbonded as standard configuration: Target is supplied unbonded; optional backing plate bonding must be specified separately, adding a procurement step and potential thermal interface considerations for high-power sputtering.
- Surface roughness may limit ultra-smooth films: Typical turned/ground surface finish Ra ≤1.6 µm may require additional polishing for applications demanding sub-micrometer film smoothness or critical optical coatings.
