The continuous growth of mobile phone production is driving the demand for HDI boards. China plays an important role in the world's mobile phone manufacturing industry. Since Motorola fully adopted HDI boards to manufacture mobile phones in 2002, more than 90% of mobile phone motherboards have adopt......

1. It can reduce the cost of HDI PCB: When the density of PCB increases to more than eight-layer board, it is manufactured with HDI, and its cost will be lower than that of the traditional complex pressing process.

Heavy copper PCBs are manufactured with 4 ounces or more of copper on each layer. 4 ounce copper PCBs are most commonly used in commercial products. The concentration of copper can be as high as 200 ounces per square foot.

Just like the standard PCB manufacturing method, heavy copper PCB manufacturing requires more delicate processing.

When designing a circuit, factors such as thermal stress are very important, and engineers should eliminate thermal stress as much as possible. Over time, PCB manufacturing processes have continued to evolve, and various PCB technologies have been invented, such as aluminum PCBs, which can handle t......

The advantages of heavy copper PCB make it the top priority for the development of high-power circuits. The heavy copper concentration can handle high power and high heat, which is why high-power circuits have been developed using this technology. Such circuits cannot be developed with low-copper co......
