Applications
Professionals across multiple industries trust tungsten probe tips from Yolo for their exceptional precision and endurance.
Here's how our probes are used in the real world:
1. LED Chip Testing and Quality Inspection
In LED manufacturing, probes must make precise electrical contact with tiny chip surfaces without causing damage.
-
Why our probes are ideal:
-
High hardness and elasticity prevent bending or tip deformation.
-
Non-destructive probing protects sensitive chip structures.
-
Custom tip shapes improve contact and reduce false signals.
-
-
Used in: Chip testing equipment, probe stations, and automated LED quality control setups.
2. Semiconductor Wafer Testing and IC Probing
Semiconductor fabs rely on ultra-precise probing for wafer-level testing, failure analysis, and debugging of integrated circuits.
-
Why our probes are ideal:
-
Sub-micron tip radius for contacting densely packed test pads.
-
Reliable conductivity ensures accurate voltage/current readings.
-
Compatibility with probe cards and precision manipulators.
-
-
Used in: Wafer sorters, memory and logic IC testing, R&D labs.
3. Focused Ion Beam (FIB) Systems
In FIB-based sample prep, especially for TEM lamella lift-out, tungsten probes act as manipulators to lift and place ultra-thin samples.
-
Why our probes are ideal:
-
Custom tip shapes compatible with Thermo Fisher EasyLift, Zeiss, and other systems.
-
Tip radius as small as 50 nanometers ensures minimal contact force.
-
Ra0.25 or better finish for clean handling under electron and ion beams.
-
-
Used in: Failure analysis labs, nano-fabrication labs, academic research facilities.
4. In-Situ TEM Sample Preparation
TEM requires samples that are ultra-thin and cleanly lifted from the substrate. Probe tips help extract these from the bulk material.
-
Why our probes are ideal:
-
Strong yet precise enough to lift fragile lamella without breakage.
-
Customization to fit different lift-out grid holders.
-
No tip contamination ensures clearer TEM imaging results.
-
-
Used in: Transmission electron microscopy, materials research, nanoscale defect analysis.
5. Micro-Mechanical and MEMS Testing
MEMS and micro-mechanical systems require fine-scale manipulation and mechanical testing with precision force application.
-
Why our probes are ideal:
-
High stiffness and elasticity for applying nano-Newton-scale forces.
-
Optional coatings and sleeves to adapt to varied materials.
-
Smooth tips reduce risk of breakage or sample scratching.
-
-
Used in: MEMS testing platforms, nano-indentation systems, material deformation analysis.

Company Profile
Yolo metal materials technology., Ltd, founded in 2000, is a manufacturer who engaged in the raw materials and precision parts production of tungsten and molybdenum. And now, Yolo exported to many countries over many years.
We have a group of professional processing technicians to supply customers with tungsten and molybdenum parts solutions.
Especially for some high-tech requirements, high standards, difficult to machine, such as thin probe, thin tungsten tube, NDB fusion technology resistance welding electrode.
Our Story
Finding a low price for any product is easy. What's difficult is finding high-quality products that will meet your needs.
However, we are in an era where most companies produce low-cost, easy-to-manufacturer, simple tungsten, and molybdenum products. They do this to achieve high sales and quick profits.
To deliver the best tungsten products, our president, also the general engineer, Mr. Ma, has been investing his 20-year experience and expertise in the research and development of high-quality tungsten products for our clients.
He aims to meet most end-users' customized requests for smaller, thinner, more complex, more precise tungsten and molybdenum products and production lines.
He's committed to end-products that have a better life than those in the market.
Yes, since we began in 2000, we don't follow the practices of other companies.
But what motivated Yolo Metal to start this journey to precision manufacturing of high-quality tungsten?
Mr. Ma, an entrepreneur who started from scratch in Luoyang, China, is aware of three crucial facts:
In the world's eye, made-in-China means low-level quality.
There's limited working space. Tight budgets prevent start-UPS from embarking on the large tungsten and molybdenum business This knowledge set him on a mission to build something different. He wanted something that could prove the made-in-China strength and our ingenuity spirit.
"My wish since the day I started this company was to put a higher priority on high precision rather than on simple technology. " Ma Said. At Yolo, we take pride in being front-runners in the complexity and extremeness of tungsten and molybdenum production. Our goal is to see our metal landing at the bottom of our customer's success ladder" Mr. Ma commented
A tight spot
This practice was caught in a tight spot from the start. This is because many customers did not trust the quality of Chinese products, especially precision products with high tolerance requirements and complex processing.
But after trying our products, the users have found that Yolo's products are as good as their products. Our products match up whether it is in the tolerance control or the difficult mechanical processing!
In 2016, as a leader in response to national environmental protection policies, we expanded the area of our factory and relocated to a new industrial park almost 30kilometers away from the original site.
What about the workers?
Most of them chose to follow our footprints.
Chou, the QC, has stayed with us for nearly 18 years
Li, the machining worker, 12 years
Wang, the technician, 15 years
The names on the list could go on and on.
What makes a great company tick? Why do some companies make the leap from good to great? How and why do some thrive in chaos?
No enterprise can become or remain truly great without a core set of principles to preserve and build upon. These principles serve as an anchor and guide in the face of an ever-changing world.
At the same time, no company can remain great without stimulating progress-change, renewal, improvement, and the pursuit of BHAGS. YOLO maintains long-term research and study of the market.
It develops new products and new application areas to keep providing customers with a variety of tungsten and molybdenum products and customized services.
