The double-sided structure also provides more space and capacity to accommodate various components and functions.
The role of pure nickel sheets in new energy batteries: Due to their excellent properties, nickel occupies an important place in the field of battery technology. As the positive electrode of new energy batteries, pure nickel sheet has excellent electrical conductivity, corrosion resistance, and thermal stability. By combining pure nickel with other elements, battery manufacturers can optimize the battery’s performance, increasing its energy density and overall lifetime. Pure nickel sheets help improve the efficiency and safety of new energy batteries by promoting stable electrochemical reactions.
Below, we will analyze how the combination of Capel 2-layer flexible circuit boards and pure nickel sheets can bring
technological innovation to the new energy battery industry based on visualized product data.
It can be known from the product attributes, that the line width and line spacing values in the PCB design are 0.15mm and 0.1mm, respectively, indicating that the traces or conductive paths on the board are narrow enough and closely spaced. This precision helps ensure the accurate transmission of signals within the new energy battery system, minimizing any potential signal corruption or interference. The board thickness consists of a 0.15 mm thin flexible printed circuit (FPC) layer and a 1.6 mm thick base layer. This combination of layers provides a balance of durability and stability to the PCB. The FPC layer is thin and flexible, allowing the board to be bent or shaped as needed, while the thicker base layer adds strength and rigidity to the overall structure of the PCB. Copper Thickness, specified as 1 oz, refers to the amount of copper coating on the conductive traces of the PCB. 1oz copper thickness is a common standard and provides high conductivity. The copper coating ensures low resistance and efficient transmission of electrical signals, helping to improve the overall performance and reliability of the PCB.
In PCB manufacturing, film thickness is really critical to provide insulation and protection for electronic components. In this particular product, the film thickness is specified at 50μm (micrometers), which ensures adequate insulation between conductive traces and prevents short circuits or signal interference. Also, the surface finish of choice for this PCB is ENIG (Electroless Nickel Immersion Gold) with a thickness of 2-3μin (micro inches). ENIG is a popular surface treatment in PCB manufacturing due to its excellent corrosion resistance and flatness. The nickel layer provides an anti-oxidation barrier, ensuring long-term durability, while the gold layer provides a reliable contact surface for electrical connections. The combination of 50μm film thickness and ENIG surface treatment helps to improve the insulation, protection, durability and overall quality of circuit boards, making them suitable for reliable operation of electronic equipment.
