Used ACCRETECH / TSK Probers for Sale | Reliable Wafer Testing Solutions

1. Introduction

In the fast-paced world of semiconductor manufacturing, every tool in the production line plays a vital role in ensuring performance, yield, and reliability. Among these tools, wafer probers are indispensable for electrical testing before packaging, helping fabs identify defects early and optimize yields.

ACCRETECH / TSK probers have established themselves as industry standards due to their accuracy, stability, and compatibility with a wide range of testers. However, the cost of new systems can be prohibitive, especially for smaller fabs, testing facilities, and R&D labs. This is where the market for used ACCRETECH / TSK probers for sale becomes highly attractive—providing proven performance at a fraction of the cost.

2. What Are ACCRETECH / TSK Probers?

ACCRETECH (Tokyo Seimitsu), known by its TSK brand, is a global leader in semiconductor test equipment. TSK wafer probers are designed to handle wafers with extreme precision, ensuring accurate positioning, stable contact, and reliable electrical measurements during wafer-level chip probing.

Key applications include:

• Wafer-level electrical testing for logic, memory, and analog devices

• Chip probing (CP) for identifying good and defective dies before assembly

• Research and development environments requiring flexibility and accuracy

Their reputation for durability, ease of integration, and process stability has made TSK probers a trusted choice for fabs worldwide.

3. Benefits of Choosing Used Probers

Purchasing a used or refurbished ACCRETECH / TSK prober offers several advantages:

• Significant Cost Savings – Used systems are often available at 40–70% lower cost compared to brand-new equipment.

• Proven Reliability – These probers have a strong track record in production fabs, ensuring robust and repeatable performance.

• Shorter Lead Times – Instead of waiting months for a new system, used equipment can often be delivered and installed quickly.

• Wide Availability of Spares – With large numbers of TSK probers still in operation globally, consumables, chucks, and spare parts are readily accessible.

• Third-Party Support Options – Many service providers specialize in refurbishing, upgrading, and maintaining these probers, extending their useful life.

For many fabs, buying used equipment is a smart investment strategy, balancing cost efficiency with reliable performance.

4. Popular ACCRETECH / TSK Prober Models

Over the years, ACCRETECH / TSK has introduced a wide range of wafer probers, each designed to meet different fab and R&D requirements. When exploring used ACCRETECH / TSK probers for sale, buyers will most commonly encounter the following models:

• UF200 / UF200SA – Compact 200mm probers widely used for memory and logic device testing. Known for stability and ease of integration.

• AP200 / AP3000 / AP3000e – Advanced probers with higher throughput, automation features, and improved alignment accuracy. Ideal for large-scale production fabs.

• UF3000 Series – Designed for 300mm wafer probing with superior precision and reliability. Frequently found in advanced process nodes and high-volume manufacturing environments.

These models continue to be in high demand because of their durability, ease of maintenance, and global support network. When sourced from a trusted supplier, used TSK probers can deliver years of additional service life with strong return on investment.

5. Key Considerations When Buying a Used Prober

While used ACCRETECH / TSK probers for sale can provide excellent value, buyers should carefully evaluate several factors to avoid unexpected costs or operational issues. Here are the most important considerations:

1. Equipment Condition

• As-Is: Sold in current condition, usually without warranty. Lower upfront cost but higher risk.

• Refurbished: Inspected, repaired, and tested by professionals. Offers better reliability.

• Fully Upgraded: Equipped with modern software, hardware, and accessories—close to new tool performance.

2. Compatibility with Testers

• Ensure the prober is compatible with your tester platform (e.g., Advantest, Teradyne, Verigy).

• Check for interface kits or adapters if mixing different systems.

3. Consumables and Accessories

• Confirm availability of chucks, manipulators, probe cards, and calibration tools.

• Missing consumables can add significant cost if purchased separately.

4. Service and Support

• Verify whether the seller provides installation, training, and after-sales service.

• Access to spare parts and experienced engineers is crucial for long-term tool uptime.

5. Supplier Reputation

• Buying from a trusted supplier reduces risks of hidden defects.

• Look for vendors with proven track records in refurbishment and semiconductor tool support.

By evaluating these factors before purchase, fabs and labs can make informed decisions and maximize the ROI from their used prober investment.

6. Why Buy from a Trusted Supplier

Purchasing a used ACCRETECH / TSK prober is not simply about finding the lowest price—it’s about securing long-term reliability and minimizing risks. Many buyers have learned the hard way that equipment from unverified sources can lead to hidden costs, frequent breakdowns, and extended downtime.

Working with a trusted supplier provides several key advantages:

• Certified Refurbishment – Tools are inspected, repaired, and tested to meet industry standards, ensuring stable performance.

• Installation & Training – Professional engineers can handle setup, calibration, and operator training, reducing ramp-up time.

• After-Sales Service – Reliable suppliers offer ongoing maintenance, spare parts, and technical support.

• Transparent Equipment History – Buyers gain confidence from knowing the tool’s origin, usage record, and refurbishment details.

• Reduced Risk – Properly refurbished tools are less likely to fail unexpectedly, protecting fab productivity.

In the competitive semiconductor industry, these advantages translate directly into higher uptime, better yields, and lower total cost of ownership (TCO). Choosing the right partner for your equipment purchase is just as important as selecting the right model itself.

7. Conclusion

Used ACCRETECH / TSK probers for sale represent a smart and cost-effective choice for fabs, testing facilities, and R&D labs that need reliable wafer probing without the high investment of brand-new tools. With proven stability, widespread industry adoption, and readily available spare parts, these systems continue to deliver excellent value even after years of service.

By carefully considering equipment condition, tester compatibility, available consumables, and supplier reputation, buyers can secure tools that not only reduce capital costs but also maintain long-term performance. In many cases, refurbished probers can extend equipment lifecycles by several years, making them a sustainable and efficient solution for semiconductor production.
