Power Supplies - RF-Plasma-E-Gun — Used Astex A-2500 (Astex)

How Much Does Used Astex A-2500 Cost in 2026?

The Used Astex A-2500 typically costs between $2,500 and $2,500 in 2026, depending on condition and refurbishment level. Units in “B” condition, which is typical for this part, are priced around $2,500. Fully refurbished units from vendors like Ferrotec or Axus Technology can cost up to $3,000, but offer better reliability and longer lifecycle. A new A-2500 from Astex or a certified distributor costs between $6,000 and $8,000, meaning buyers can save 40–60% by opting for a used unit.

The cost of failure for a faulty A-2500 can be significant. If the unit fails during production, it can cause $10,000–$20,000 in downtime costs per hour, depending on the fab’s throughput. That’s why sourcing from a trusted refurb vendor is critical. A unit with more than 10,000 RF-hours or over 12 years old is more likely to fail prematurely. Always verify the unit’s condition and refurbishment history before purchase.

Used Astex A-2500 Specifications and Compatible Tools

The Astex A-2500 is a 2500W RF power supply designed for use in plasma and e-gun systems. It typically operates at 13.56 MHz with a voltage range of 0–1500V and a current range of 0–10A. The unit is commonly used in deposition and etch tools, particularly in systems from manufacturers like Applied Materials and Lam Research. It is often found in tools from the Centura and Endura platforms, typically installed between 2005 and 2010.

However, this unit is not compatible with newer 180mm or 200mm tools that use the Astex A-3000 or A-4000 power supply models. Attempting to install the A-2500 in such systems can lead to equipment misalignment and plasma instability, resulting in $5,000–$10,000 in repair costs and potential wafer loss. Always confirm compatibility with the tool’s schematics and part number before installation.

What to Check Before Buying a Used Astex A-2500 in 2026

1. Verify RF-Hour Count: Units with more than 10,000 RF-hours are at higher risk of capacitor and coil degradation. Reject any unit with over 12,000 RF-hours.

2. Test with a Vector Network Analyzer (VNA): This will confirm the unit’s impedance matching and signal integrity. A mismatch of more than ±5 ohms indicates potential failure.

3. Check Capacitor and Transformer Health: Use a capacitance meter and transformer tester to ensure components are within spec. Capacitors should be within ±10% of rated value.

4. Review Refurbishment History: Ask for a refurb log from the seller. Units refurbished within the last 2–3 years are more likely to perform reliably.

5. Reject if Over 15 Years Old: The A-2500 is not designed for long-term use beyond 15 years. Units older than this are likely to fail within 6–12 months of installation, leading to $7,000–$15,000 in unplanned downtime.

FAQ

Q: Can I use the Astex A-2500 in a newer 200mm tool?
A: No. The A-2500 is not compatible with 200mm tools that use the Astex A-3000 or A-4000 power supply. Attempting to install it can lead to $5,000–$10,000 in repair costs due to incompatibility.

Q: Should I buy a used A-2500 with 12,500 RF-hours?
A: No. Units with more than 12,000 RF-hours are at high risk of failure. A unit with 12,500 RF-hours is likely to fail within 6–12 months, leading to $7,000–$15,000 in downtime.

Q: How long can I expect a used A-2500 to last?
A: A well-refurbished unit with less than 10,000 RF-hours and under 12 years old can last 3–5 years in a typical fab environment. Beyond that, the risk of failure increases significantly.

Q: Is the A-2500 more cost-effective than the A-3000?
A: Yes. The A-2500 is typically $1,500–$2,000 cheaper than the A-3000 in the used market. However, it is not compatible with newer tools, so the savings may be offset by incompatibility costs.

Q: What’s the best way to test the A-2500 before installation?
A: Use a Vector Network Analyzer (VNA) to test impedance and a capacitance meter to check capacitors. Any deviation beyond ±5 ohms or ±10% of rated capacitance is a red flag.
