Latest Patents

One of Takayama's key inventions is a metal-based circuit board, which is designed to reduce the influence of thermal expansion. This patent features a unique structure where an insulating layer A, which has a large coefficient of thermal expansion, is sandwiched between insulating layers B that have a smaller coefficient of thermal expansion. This configuration allows the insulating layers B to contract and expand, effectively suppressing the contraction and expansion of insulating layer A. As a result, the stress in the direction of negating the stress is minimized. This innovation not only reduces warpage or distortion but also maintains the bonding strength of the upper and lower layers, ensuring that the degree of freedom for circuit design remains intact. The outcome is a highly reliable circuit structure.
