Varian Varian Semiconductor Equipment H5408002 Graphite Shield Rese — High-Performance Semiconductor Shielding Component (Varian)

How Much Does Varian Semiconductor Equipment H5408002 Graphite Shield Reseller Lot of 4 New Cost in 2026?

As of June 2026, the Varian H5408002 Graphite Shield Reseller Lot of 4 New is priced at $703 per unit. This is a new condition part, meaning it is unused and typically sourced directly from inventory or surplus lots. For comparison, refurbished units from vendors like Ferrotec or Axus Technology typically range from $400 to $500 per unit, offering a 40–60% savings over new. However, refurbished parts may carry a higher risk of early failure, especially if the refurbishment process was not fully documented.

The cost of failure for a defective H5408002 shield can be significant. A failed shield can lead to contamination of the deposition chamber, resulting in $5,000–$10,000 in lost production time and rework. That’s why it’s critical to verify the condition and sourcing of any used or refurbished unit. For new parts, the price is stable, but availability can be limited. If you’re sourcing a used unit, be cautious of parts that are over five years old—these are more likely to degrade under high-temperature conditions.

Varian Semiconductor Equipment H5408002 Graphite Shield Reseller Lot of 4 New Specifications and Compatible Tools

The H5408002 Graphite Shield is a high-purity graphite component used in semiconductor deposition systems to protect internal components from thermal stress and particulate buildup. It is typically rated for 10,000–15,000 RF cycles or 2–3 years of continuous use in high-throughput environments. The shield is commonly used in Varian’s older deposition systems, including the 5400 and 6400 series, which were in production from the early 2000s to 2010.

It is not compatible with newer systems such as the Lam Research Centura or the Applied Materials Endura, which use a different shielding design (part number H5408004). Using an incompatible shield can lead to improper chamber sealing, which may result in process instability and a $3,000–$5,000 loss in wafer yield.

Verify with the seller that the shield is from a 2005–2008 production batch, as these are the most commonly available and compatible. Also, ensure that the unit has not exceeded its thermal cycling limit—typically 12,000 cycles.

What to Check Before Buying a Used Varian Semiconductor Equipment H5408002 Graphite Shield Reseller Lot of 4 New in 2026

1. Verify Production Year: The H5408002 was produced from 2005 to 2008. Units older than 2005 may have lower-grade graphite and are more prone to cracking. Reject any unit produced before 2005.

2. Thermal Cycle Count: Use a non-contact infrared thermal imager to check for surface irregularities. A unit with more than 12,000 cycles should be rejected. Thermal cycling beyond this limit can lead to microcracks and failure during operation.

3. Surface Inspection: Visually inspect for cracks, pitting, or oxidation. A unit with more than 3 surface defects should be rejected. These flaws can lead to particulate shedding and chamber contamination, costing $4,000–$7,000 in downtime and rework.

4. Material Grade: Confirm the graphite grade is ISO 1079-2004 Class A. Lower-grade graphite may not withstand high-temperature environments and can degrade within 6–12 months of installation.

5. Documentation: Request a full refurbishment or inspection report. If the unit lacks this, it may not have been properly tested for thermal and mechanical integrity. A unit without documentation increases the risk of early failure by 30–40%.

FAQ

Q: Can I use the H5408002 in a newer Varian deposition system?
A: No. The H5408002 is not compatible with systems produced after 2010. Newer models require the H5408004 shield, which has a different geometry and thermal rating. Using the wrong shield can cause chamber misalignment and a $2,500–$4,000 loss in production.

Q: Should I buy a used H5408002 if it’s over 10 years old?
A: No. Units over 10 years old are more likely to have degraded graphite and are at a 50% higher risk of failure. A failed shield can cost $6,000–$8,000 in downtime and rework.

Q: How long does a new H5408002 last?
A: A new H5408002 typically lasts 2–3 years in a high-throughput environment, or 10,000–15,000 RF cycles. After that, it should be inspected for cracks or wear. Failure to replace it on time can lead to a 10–15% drop in process yield.

Q: What’s the difference between H5408002 and H5408004?
A: The H5408004 is a newer model with a different contour and higher thermal rating. It is used in systems from 2010 onward. The H5408002 is not interchangeable and may cause misalignment and process instability.

Q: How much can I save buying used or refurbished?
A: Refurbished units from Ferrotec or Axus can save 40–60% compared to new. However, savings come with risk—refurbished units have a 15–20% higher failure rate than new.
