The Problem: High Defect Rates in Copper Strip Manufacturing
According to Zhang and Zheng (2016), surface defects account for
79.2% of quality complaints in precision copper strips, with
physical defects contributing 67.4%. One manufacturer reported a
5.44% scrap rate, costing millions annually.
The consequences are severe: pinholes degrade conductivity in
electronics, cracks in automotive heat sinks risk thermal runaway,
and for IC lead frames (C19400 strips), internal stress-induced
warping or poor surface adhesion disrupts chip integration. A
semiconductor client rejected entire batches due to etching
defects, resulting in contractual penalties and delayed deliveries.
These quality issues aren't new to the copper strip industry. To
transform high-complaint operations into no-complaint
manufacturing, we focus on prevention at the source: copper billet
inspection before strip formation. By eliminating physical defects
in raw materials, we dramatically reduce downstream defect rates.
Our core system is a sophisticated mobile scanning platform
featuring a powerful 6-probe A-scan ultrasonic configuration. This multi-probe setup ensures rapid, comprehensive coverage with
detailed inspections across the entire billet surface. The
water-immersed ultrasonic transducers identify internal defects by
detecting prominent waveform changes caused by wave reflection
differences.
Key Features & Capabilities:
- Unmatched Customization & Engineering: This is the cornerstone of our service. We don't just sell a
machine; we deliver a solution. Our engineering team works directly
with you to modify and design the mechanical scanning system,
fixtures, and software to perfectly match your specific component.
Your unique inspection challenge is our blueprint for innovation.
- Advanced 6-Probe A-Scan Technology: Our system's six A-scan ultrasonic probes work in concert to
provide a detailed, multi-point analysis of the material's internal
structure. This allows for the precise detection, localization, and
characterization of flaws such as internal cracks, voids, porosity,
and inclusions with exceptional reliability
- Optimized for Plate-Like Components: While originally designed for high-demand applications like copper
strip billets, our solution is expertly adapted for any flat or
plate-like metal part. The mobile scanning mechanism ensures 100%
inspection coverage, essential for industries where material
integrity is non-negotiable

So why under water? Immersion Ultrasonic Testing Explained
Reduce noise / disturbance from the air
During the rolling process, the surface of a Copper Strip Billet
may have minor roughness, oxidation layers, or unevenness. With
traditional contact testing (where the probe touches the part
directly), these microscopic air gaps would severely disrupt the
ultrasonic signal, causing significant noise and erroneous
readings. By immersing the billet in water, the fluid fills every
micro-gap, ensuring that the ultrasonic energy is transmitted into
the copper stably and uniformly. This results in a clean, reliable,
and repeatable inspection signal.
Contactless, Extend life expectancy of the probes
In a in-line inspection environment, direct contact would cause
rapid wear on both the transducer and the billet surface. This is
not only costly but also leads to constantly changing test
sensitivity as the probe degrades. Immersion UT is a non-contact
method. The transducer maintains a fixed distance from the
workpiece while moving through the water, eliminating wear and tear
and ensuring high consistency throughout the entire inspection
process.
Higher resolution, higher sensitivity
Immersion testing readily allows for the use of focused transducers. These probes act like a magnifying glass, concentrating the
ultrasonic energy at a specific depth within the copper billet.
This dramatically increases the sensitivity and resolution of the
inspection, enabling the precise detection of minute internal
defects such as inclusions, porosity, and micro-cracks—all of which
are critical-to-quality control points for producing high-grade
copper strips.
