We developed solvent-soluble polyimides with good heat resistance and low dielectric constant (Dk) / dissipation factor (Df) characteristics by optimizing the composition ratio of the aliphatic, cycloaliphatic, and aromatic groups present in the polyimide back bone. We found that the adhesives prepared using our polyimides showed good adhesion to polyimide films and low profile copper foils and low...
The advance of wireless communications and broadband technologies is dramatically progressing with the remarkable growth of the market of information technology equipments such as mobile phones and tablets. In order to meet ever-enlargement of transmitting data, transmission frequency in circuits tends to become high and the integrity of a high-frequency signal can be damaged by transmission loss...
