We’ve got you covered—from probe pins and IC sockets to probe cards and testing jigs. Whether you need a small tweak to an existing part or a brand-new design, we’ll make it happen. We also provide replacements for discontinued third-party products, so your testing process stays smooth and uninterrupted. Tell us what you need—we’ll build it for you.
Customization Tailored to DUT Characteristics and Test System Requirements
Modifications that Match Your Testing Needs
Fully customizable to fit your needs
We offer a wide range of customization options, including: Custom tip shapes, stroke length adjustment, Pipe length variations, Spring force optimization amd more. Our goal is to provide the perfect probe for your exact application.
Advanced materials & surface treatment
To reduce contact failures and wear, we carefully select alloys and surface treatments that best match your testing conditions. This ensures greater reliability, even under challenging environments.
Precision engineering for fine-pitch
Using advanced precision machining, we support applications requiring extremely fine pitch or miniature contact areas. Even for difficult dimensions or force requirements, our custom probes deliver performance that standard products can’t match.
Maximizing Test Performance Through Customized Probe Material Solutions
In different testing environments, the reliability of probes plays a crucial role in achieving accurate, stable measurements. One of the most effective ways to ensure this is by selecting the optimal probe materials tailored to your specific test conditions.
In cases where durability is a concern, changing the material or surface treatment can help extend the probe’s lifespan. However, it is also important to consider potential side effects, such as an increase in resistance. By carefully choosing the right materials and surface treatments for each situation, we help our customers avoid common issues such as premature wear, unstable resistance, or contact failure.

Real-World Testing Challenges — and How we solve them
Testing isn’t always smooth sailing — and we understand the frustration of poor contact or performance drops. That’s why we’ve designed targeted solutions to solve the most common probe-related issues and help you get the accuracy and reliability you need.
Insufficient contact force
- Concern
Weak internal contact or low spring force leads to high resistance.
- Solution
We customize the spring force to boost performance. For high-heat environments, switching to stainless steel (SUS) springs helps maintain long-term stability.
Tip deformation
- Concern
Probes wear out from repeated contact with hard terminals, reducing their effectiveness.
- Solution
We use materials like SK steel and fine-tune the tip shape to improve durability and maintain strong contact.
Tip surface degradation
- Concern
Plating peels off over time, exposing the base metal to oxidation and raising resistance.
- Solution
We switch to oxidation-resistant alloys and solder-resistant materials. For top-tier performance, CNT plating increases current capacity, and routine cleaning prevents debris buildup.
