The target is supplied with a turned or ground surface and dimensional tolerances that must be preserved through handling and installation. Bonding and configuration options must be confirmed before the target is mounted in a deposition system.
- Surface finish preservation: Preserve the turned or ground target face with Ra≤1.6 µm typical until installation.
- Dimensional verification: Verify the target diameter and thickness against the stated ±0.10 mm typical tolerances before installation.
- Bonding configuration: Select copper (Cu) backing plate bonding during quotation when the deposition system requires a bonded target.
- Configuration compatibility review: Confirm the model, working range, compatibility, consumables, and required configuration before requesting quotation support.
What is the maximum total critical impurity level for the 99.995% lead sputtering target, and how does it affect film purity in semiconductor research?
The typical total critical impurities are ≤50 ppm for this Pb 4N5 grade target. This low impurity threshold ensures minimal contamination during sputter deposition, which is critical for maintaining controlled stoichiometry in semiconductor or functional thin-film research where trace elements can alter electrical or optical properties.
Can this unbonded lead sputtering target be directly mounted in a standard planar magnetron, or is backplate bonding required?
The target is supplied unbonded by default, with optional Cu backing plate bonding available. For direct mounting in a standard planar magnetron, unbonded targets require a compatible backing plate or clamping system to ensure thermal and electrical contact; the optional bonding service provides a ready-to-mount assembly. Confirm compatibility with your sputter gun before ordering.
What surface roughness and dimensional tolerances are typical for this lead sputtering target, and do they vary with thickness or diameter?
The target has a turned/ground surface with Ra ≤1.6 µm typical, and dimensional tolerances of ±0.10 mm for both diameter and thickness. These specifications are typical across all available thicknesses (3–6.35 mm) and diameters (25.4–101.6 mm), but final parameters are confirmed by batch inspection and the agreed configuration.
The Atomfair AF-PB-99N995 is a 99.995% pure round planar lead sputtering target with Pb 4N5 grade, 11.34 g/cm³ density, 20.6 micro-ohm cm resistivity, Ra≤1.6 μm typical surface finish, and ±0.10 mm typical dimensional tolerances. It is available with unbonded or optional Cu backing plate bonding across multiple diameters and thicknesses for low-melting-point and semiconductor/functional film research.
Positive
- 99.995% Pb 4N5 purity grade: Typical total critical impurities are ≤50 ppm, providing controlled material purity for reproducible sputtering of low-melting-point and semiconductor/functional films.
- Broad round planar geometry options: Available thicknesses from 3 mm to 6.35 mm and diameters from 25.4 mm to 101.6 mm, with ±0.10 mm typical dimensional tolerance, allow matching to different sputtering tool configurations.
Trade-offs
- Unbonded by default; bonding must be specified: The target is supplied unbonded with optional Cu backing plate bonding, so the thermal and electrical contact configuration must be confirmed before quotation to suit the destination sputtering system.
- Typical values require pre-order confirmation: Surface finish Ra≤1.6 μm and dimensional tolerance ±0.10 mm are listed as typical, with final parameters confirmed by batch inspection and the agreed configuration, requiring explicit verification against application needs.
