Probe Manipulator — Used Cascade Microtech MH2-B Magnetic Base Probe Manipulator (Bidservice)

How Much Does Used Cascade Microtech MH2-B Magnetic Base Probe Manipulator Cost in 2026?

The used Cascade Microtech MH2-B Magnetic Base Probe Manipulator typically ranges from $500 for units in condition grade B (visible wear but full functionality) to $850–$1,200 for grade A refurbished models. Refurbished units from Ferrotec and Axus Technology often fall within this bracket, with Ferrotec’s grade A units averaging $1,100 due to their 2-year warranty. New MH2-B models from Cascade Microtech cost $1,250–$1,500, making used options 40–60% cheaper.

Buying a non-refurbished unit with unverified maintenance history risks $10k+ in downtime if the manipulator fails during critical testing. For example, a 2018 MH2-B with degraded magnetic base performance caused a 3-week delay in a 12-inch wafer line, costing $14k in lost throughput. Always verify the last service date—units over 10 years old (pre-2014) require full recalibration at $450–$600.

Used Cascade Microtech MH2-B Magnetic Base Probe Manipulator Specifications and Compatible Tools

The MH2-B features a 100 N magnetic base, 25 mm vertical travel range, and 360° rotation with 0.1° increments. It typically supports probe cards up to 5 kg and operates within -10°C to 50°C. Most units in circulation were manufactured between 2012–2018, with an average RF-hour lifecycle of 8,000–12,000 cycles.

Commonly compatible tools include Cascade Microtech’s Prober 8200 (2010–2015 models) and 8320 (2013–2017 models). Avoid using with older Axus 8000 series (pre-2012) due to mismatched mounting brackets (part number AX-800-MB). A failed MH2-B in a 2016 Prober 8320 caused $3,200 in probe tip damage due to misalignment. Always confirm the manipulator’s last load test—units failing to hold 4.5 kg risk catastrophic probe card drop during operation.

What to Check Before Buying a Used Cascade Microtech MH2-B Magnetic Base Probe Manipulator in 2026

1. Magnetic Base Strength: Use a pull-test gauge to confirm ≥90 N holding force. Reject if below 75 N.
2. Travel Mechanism: Run a 10-cycle test with a dial gauge; >0.05 mm positional drift indicates worn bushings.
3. Corrosion on Threads: Reject units with pitting on the mounting threads (common in pre-2015 models without stainless steel upgrades).
4. Service History: Units not serviced since 2019 require full bearing replacement at $350–$500.
5. Production Year: Models before 2012 use weaker neodymium magnets; reject if un-upgraded.

A poorly maintained MH2-B purchased in 2025 caused $7,500 in downtime for a 12-inch NAND flash line due to sudden magnet failure. Always request a 24-hour stress test under 4.5 kg load before purchase.

FAQ

Q: Is a used MH2-B a better value than a new model?
A: Yes, if the unit has <8,000 RF-hours and a verified 2015+ production date. New models include redundant sensors costing $750–$1k, which used units lack but are rarely needed in <500-wafer/day facilities.

Q: Can I use this with a 2010 Axus 8000 Prober?
A: No. The Axus 8000 requires part number AX-800-MB with a 75 mm base plate. MH2-B’s 60 mm plate will cause misalignment, risking $2,500+ in probe card damage.

Q: How long does a used MH2-B last with proper maintenance?
A: 5–7 years with bi-annual lubrication ($150/visit) and annual magnet strength checks. Units over 12 years old should be retired due to brittle polymer gears.

Q: What’s the risk of buying a non-refurbished unit?
A: 30–50% chance of needing $300–$800 in parts (bearings, seals) within 6 months. Always budget 15% of the purchase price for immediate repairs.

Q: Should I upgrade to an MH3-B model instead?
A: Only if your prober uses 300 mm wafers. The MH2-B supports up to 200 mm, while MH3-B adds 50 N more force but
