Tin plated copper foil and high-end tin plated copper foil are made by sandwiching a soft copper foil between two thin layers of tin

Tin plated copper foil and high-end tin plated copper foil have the following characteristics:

2. Can be reflow soldered;

3. Excellent heat resistance;

4. Excellent environmental durability;

5. Excellent super bending resistance;

    Tin plated copper foilIt is a soft copper foil sandwiched between two thin layers of tin. Compared to pure copper foil surfaces, tin surfaces provide better environmental resistance, and both are easy to solder. This special foil structure is typically recommended for applications that require maximum shielding effectiveness and good environmental resistance.

Copper foil is a type of negative electrolytic material, which is a thin and continuous metal foil deposited on the substrate layer of a circuit board. As the conductor of a PCB, it is easy to adhere to the insulation layer, receive printing protection layer, and form circuit patterns after corrosion. Copper foil has low surface oxygen characteristics and can be attached to various substrates such as metals and insulation materials. It has a wide temperature range and is mainly used for electromagnetic shielding and anti-static. When the conductive copper foil is placed on the substrate surface and combined with the metal substrate, it has excellent conductivity and provides electromagnetic shielding effect. It can be divided into self-adhesive copper foilDouble conductive copper foilElectronic grade copper foil (with a purity of over 99.7% and a thickness of 5um-105um) is one of the fundamental materials in the electronic industry, and the electronic information industry is rapidly developing,Electronic grade copper foilThe usage of the product is increasing, and it is widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, civilian televisions, video recorders, CD players, copiers, telephones, air conditioning systems, automotive electronic components, game consoles, etc. The demand for electronic grade copper foil, especially high-performance electronic grade copper foil, is increasing in both domestic and international markets.
