Latest Patents

One of Totani's latest patents is for a flexible laminated sheet manufacturing method. This method involves thermocompression-bonding an insulation film made of liquid crystal polymer onto a metal foil between endless belts. The process includes heating the flexible laminated sheet to a temperature range that is 45° C. lower than the melting point of the liquid crystal polymer to 5° C. lower than the melting point. Additionally, the method requires slowly cooling the sheet to ensure an exit temperature that is between 235° C. and 100° C. lower than the melting point.

Another notable patent focuses on a printed circuit board and a flexible printed circuit (FPC) board connection structure. In this design, both boards are given a multilayer structure with alternating insulating films and interconnection patterns. The FPC board features distributed connecting signal lines among the multilayered interconnection patterns, while the printed circuit board connects to lands on its connection face using inner layer interconnection patterns. This innovative approach significantly increases the number of connecting signal lines between the two boards.
