300042701 Specifications and Compatible Tools

The 300042701 is a 12-inch aluminum disk rated for 5 kW RF power, 13.56 MHz frequency, and 480 VDC bias. It supports vacuum levels down to 1e-5 Torr and operates in temperatures up to 200°C. Compatible with Varian VIISta 80 (2002–2008) and VIISta 80XP (2005–2010). Do not use with part number 300042702, which is a high-power variant for VIISta 125 systems. Always verify the tool’s serial number against Varian’s 2005 compatibility matrix to avoid mismatched impedance profiles.

What to Check Before Buying a Used 300042701 in 2026

Pitting depth: Use a profilometer to measure surface irregularities. Reject units with pitting >0.5 mm (avg. lifespan threshold).
RF leakage: Test with a vector network analyzer (VNA) at 13.56 MHz. Leakage >1.5 dB indicates degraded RF coupling.
Vacuum seal: Pressurize to 1e-5 Torr and monitor for 24 hours. A rise >5% confirms seal failure.
Thermal cycling history: Request service logs. Units with >5,000 thermal cycles (2026 industry average) risk microcracks.
Alignment markers: Verify laser-etched alignment codes match the VIISta 80’s spindle encoder. Mismatched codes void calibration.

Q: Is used 300042701 better than refurbished for VIISta 80?
A: Used parts are cheaper but may require near-term replacement. Refurbished units include OEM-replaced components and 12–18 month warranties, reducing 2026 downtime risk.

Q: Does 300042701 fit all VIISta 80 models?
A: No. Confirm the tool’s build year (2002–2008) and spindle type (Model A/B). Early 2002–2004 models require 300042701-A with a 3° tilt adapter.

Q: How to test 300042701 vacuum integrity?
A: Use a Pirani gauge to pressurize to 1e-5 Torr, then monitor for 24 hours. A pressure increase >0.05 Torr/hr means failed seals.

Q: What’s the 2026 lead time for sourcing?
A: 2–4 weeks after sourcing confirmation, assuming a unit with <35,00
