Used Probe Stations , Used Price | Refurbished Probers by JUNR

I. Introduction

A probe station is a precision testing platform used to perform electrical measurements on semiconductor wafers at the die level. These stations are critical in wafer-level testing before final packaging and are widely used in foundries, IC test labs, R&D departments, and failure analysis (FA) facilities.

As semiconductor manufacturing continues to demand higher accuracy and cost efficiency, many organizations are choosing used probe stations as a practical solution. Compared to brand-new systems, used probe stations offer similar functionality at a significantly lower capital investment — especially when sourced from trusted suppliers and properly refurbished.

II. What Is a Probe Station?

A probe station serves as the physical interface between a semiconductor wafer and measurement instruments. Its primary function is to position micromanipulated electrical probes onto precise locations on a wafer to evaluate electrical characteristics of each die.

III. Commonly Used Probe Station Models in Semiconductor Testing

Selecting the right probe station is a critical step in wafer-level electrical testing. Various models from globally recognized manufacturers serve different applications — from advanced RF testing to basic parametric measurements. Below is an overview of some widely adopted probe station models, commonly found in foundries, R&D labs, and IC testing facilities.

Selection Notes:

• Cascade and MPI platforms are popular in RF and high-precision environments

• TEL and Accretech dominate in production-scale CP test floors

• Electroglas systems are cost-effective choices for mid-volume testing and are widely available in the secondary market

• Signatone and Wentworth models suit academic or entry-level applications

IV. Factors That Affect the Price of Used Probe Stations

The price of a used probe station depends on a variety of technical, operational, and commercial factors. Understanding these variables is critical to making an informed purchasing decision.

1. Brand and Model

Some manufacturers have stronger market presence and resale value. For instance, Cascade Microtech, MPI, Electroglas, and TEL (Tokyo Electron) are recognized for their robust engineering and precision.

2. System Type and Feature Set

• Manual systems are generally the least expensive

• Semi-automatic systems cost more due to motion control and automation

• Fully automatic systems command higher prices but offer unmatched efficiency

• Add-on features such as thermal chuck systems, RF probe integration, and dark box enclosures increase overall value

3. Refurbishment and Condition

• As-is systems are cheaper but riskier

• Partially refurbished systems have some verified components

• Fully refurbished systems are cleaned, calibrated, and tested to meet OEM-level standards, and often come with limited warranty

4. Accessories and Inclusions

Pricing is affected by whether key components are included, such as:

• High-resolution optical microscopes

• Motorized or manual XYZ micropositioners

• Anti-vibration tables

• Probe arms or RF manipulators

• PC interface software for automation

5. Age and Usage History

Older systems with high usage cycles may be more affordable but could require additional maintenance. Lightly used systems from low-volume labs often retain better mechanical stability and optical quality.

V. Benefits of Buying Used Probe Stations

Purchasing a used probe station can be a strategic decision for semiconductor fabs, test labs, or R&D teams aiming to balance technical capability with cost-efficiency. When sourced from a reliable supplier and thoroughly inspected or refurbished, used systems can deliver performance comparable to new equipment.

Key Benefits:

1. 1. Significant Cost Reduction

   • Used systems typically offer 40–70% savings over new units.

   • Enables acquisition of higher-spec models within limited budgets.

2. 2. Shorter Lead Times

   • New systems may require months of lead time.

   • Used equipment, especially if in stock, can often be delivered and deployed within weeks.

3. 3. Customizable Configuration

   • Used probe stations can be upgraded or modified (e.g., adding thermal chuck, RF probes).

   • Allows tailoring of functionality to exact application needs.

4. 4. Sustainability and Resource Efficiency

   • Extending the life of existing equipment contributes to greener semiconductor manufacturing.

   • Reduces e-waste and capital resource consumption.

5. 5. Support for Legacy Processes

   • Certain mature nodes or specialty processes (MEMS, power semiconductors) require equipment that may no longer be available new.

   • Used systems can fill this gap.

VI. What to Look for When Buying a Used Probe Station

Choosing the right used probe station requires technical due diligence to ensure reliability, compatibility, and long-term usability. Here are key evaluation criteria:

✅ Mechanical and Optical Integrity

• Check for smooth chuck motion and stage planarity

• Inspect microscope optics for scratches, resolution, and focus control

• Evaluate manipulators and XYZ stages for repeatability and backlash

✅ System Configuration

• Confirm wafer size support (e.g., 4", 6", 8", 12")

• Ensure chuck type matches application (vacuum, thermal, triaxial)

• Validate probe arm compatibility with your measurement instruments

✅ Cleanroom Compatibility

• Determine whether the system is ISO-certified or compatible with cleanroom operation

• Review filtration and enclosure options (for dark box or EMI-sensitive work)

✅ Post-Sale Support

• Does the supplier provide documentation, software, manuals, or training?

• Is there warranty coverage or on-site installation support available?

• Are spare parts and consumables still available for the model?
