What are the main advantages of CU4000 circuit boards?

The advantages of CU4000 circuit boards are mainly reflected in the following aspects:

High performance: The CU4000 circuit board uses high-performance single-sided treated electrolytic copper foil, which has an increased mechanical bonding area, resulting in higher peel strength on the RO4000 series of semi cured sheet materials. This high-performance copper foil ensures the stability and reliability of circuit boards in various complex environments and application conditions.
Excellent adhesion: CU4000 LoPro ® It is a reverse processed electrolytic copper foil version of the CU4000 series, which uses a very thin adhesive layer to enhance the adhesion between the smooth copper foil and the medium. This excellent bonding force helps to reduce the failure rate of circuit boards, improve the reliability and service life of circuit boards.
Reducing circuit losses: CU4000 LoPro ® Copper foil can reduce circuit losses at higher frequencies, which is particularly important for the application of high-frequency circuits. Reducing circuit losses helps improve the performance and efficiency of circuit boards, reducing energy waste.
Optimizing Multi Layer Board Design: CU4000 and CU4000 LoPro ® Copper foil can be combined with RO4000 laminated board design, production and processing of multi-layer boards, optimizing the alignment and filling requirements of multi-layer boards. This makes the design of multi-layer boards more flexible and efficient, which helps to improve the integration and performance of circuit boards.
High temperature resistance and elongation: CU4000 and CU4000 LoPro ® Copper foil is a high temperature and high elongation copper foil of grade 3 in IPC-4562, which has excellent high temperature resistance and elongation performance. This enables the circuit board to maintain stable performance in high-temperature environments, meeting the needs of various high-end applications.
In summary, the CU4000 circuit board has advantages such as high performance, excellent adhesion, reduced circuit losses, optimized multi-layer board design, and high temperature resistance, making it widely applicable in various high-end application fields.
