Chemical plating methodColumnar structure
6μm ~ 140μm 1340mm (generally 1290mm) Hard Double shiny / single mat / double mat |
Physical rolling methodSpherical structure
6μm ~ 100μm 650mm Hard / Soft Single light / double light |
| Producing Difficulty | Short production cycle and relatively simple process | Long production cycle and relatively complex process |
| Processing difficulty | The product is harder, more brittle, easy to break | Controllable product state, excellent ductility, easy to mold |
| Applications | It is generally used in industries that require electrical conductivity, thermal conductivity, heat dissipation, shielding, etc. Due to the wide width of the product, there are less edge materials in production, which can save part of the processing cost. | Mostly used in high-end conductive, heat dissipation and shielding products. The products have good ductility and are easy to process and shape. The material of choice for mid- to high-end electronic components. |
| Relative Advantages | Short production cycle and relatively simple process. The wider width makes it easy to save on processing costs. And the manufacturing cost is relatively low and the price is easy for the market to accept. The thinner the thickness, the more obvious the advantage of electrolytic copper foil price compared to calendered copper foil. | Due to the high purity and density of the product, it is suitable for products with high requirements for ductility and flexibility. Moreover, the electrical conductivity and heat dissipation properties are better than those of electrolytic copper foil. The state of the product can be controlled by the process, which makes it easier to meet the processing requirements of customers. It also has better durability and fatigue resistance, so it can be used as raw material to bring longer service life to the target products. |
| Relative disadvantages | Poor ductility, difficult processing and poor durability. | There are restrictions on processing width, higher production costs and long processing cycles. |
