<p><a href="https://www.pcbccl.com/copper-foil" rel="noopener noreferrer" target="_blank">Copper foil</a> is a kind of cathode electrolytic material, a thin, continuous metal foil deposited on the base layer of the circuit board, which acts as the conductor of the PCB. It easily adheres to the insulating layer, accepts the printed protective layer, and forms a circuit pattern after corrosion. It is an important material for copper clad laminate (CCL) and printed circuit board (PCB) manufacturing.</p><p><br></p><p>Copper foil has low surface oxygen characteristics and can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range. Mainly used in electromagnetic shielding and antistatic. The conductive copper foil is placed on the surface of the substrate and combined with the metal substrate, which has excellent conductivity and provides electromagnetic shielding effect.</p><p><br></p><p>Electronic grade copper foil (purity above 99.7%, thickness 5um-105um) is one of the basic materials of the electronics industry. The electronic information industry is developing rapidly, and the use of electronic grade copper foil is increasing. The products are widely used in industrial calculators. , Communications equipment, QA equipment, lithium-ion copper foil batteries, civilian televisions, video recorders, CD players, copiers, telephones, air conditioning, automotive electronic components, game consoles, etc.</p><p><br></p><p>Performance advantages:</p><p>1. Significantly improve the consistency of the battery pack and greatly reduce the battery composition cost.</p><p>2. Improve the adhesive force between the active material and the current collector, and reduce the manufacturing cost of the pole piece.</p><p>3. Reduce polarization, increase rate and gram capacity, and improve battery performance.</p><p>4. Protect the current collector and prolong the service life of the battery.</p>
