In the fields of electrical connections, automotive electronics, new energy batteries, precision manufacturing, etc., there is a "low-key but critical" material that is playing an irreplaceable role.Small size copper strip.
It is as small as a millimeter, but it is responsible for conducting current, connecting components, and maintaining the stable operation of the system. You may never notice its existence, but as long as it has a flaw, the entire system may not work properly.
Today, let’s talk about this seemingly inconspicuous copper strip, which is known as “connecting the nerve endings of industry” - and a professional manufacturing company that is highly trusted in the industry:RaytronRaytron.
In what fields are small-sized copper strips used?
Don't underestimate it because it is small. It has many uses:
- ? Battery connector: Key conductor materials for lithium batteries, power tool batteries, and electric vehicle batteries;
- ? Terminal connection copper sheet: Widely used in automobiles, home appliances, and communication equipment;
- ? Precision electronic components: Such as FPC soft board, PCB connection, electromagnetic shielding, etc.;
- ? New energy vehicle wiring harness terminals: High-speed data transmission and current transmission carrier.
These scenarios have extremely stringent requirements on copper strips: high conductivity, high ductility, anti-oxidation, stable dimensional accuracy...and this is why not all manufacturers are capable of producing small-sized copper strips.
Why is it so difficult to make small-sized copper strips?
You may think: copper strips are just made by drawing and cutting thinner, right? But the truth is far more complicated than you think.
Small size copper strip, especiallyThickness as low as 0.05mm, width less than 10mmThe requirements for the production process of high-quality products can be described as "the truth is determined by every millimeter".
- High purity requirements for raw materials: High-precision copper or electrolytic copper must be used, with extremely low impurity content;
- The ultimate challenge of rolling technology：It requires precision equipment with more than four continuous rolling mills and an experienced operation team;
- Size control must be extremely precise: The thickness tolerance is controlled at ±0.005mm, and the width consistency control must be stable;
- Surface treatment is critical: There should be no burrs, scratches, oil stains, and it should not be easily oxidized and discolored.
