Latest Patents
One of Takasaka's latest patents is for a multilayer wiring board and method of making the same. This innovative design includes a core insulating layer with a first conductive wiring, a first insulating layer with a softening temperature lower than the core insulating layer, and a second insulating layer formed on the core insulating layer through the first insulating layer. The second insulating layer features a second conductive wiring that is electrically connected to the first conductive wiring, with a softening temperature higher than that of the first insulating layer. The first insulating layer is primarily composed of a liquid crystal polymer, while the core insulating layer and the second insulating layer are mainly made of polyimide resin or bismaleimide triazine resin. The conductive wirings are interconnected through a conductive via that penetrates the first and second insulating layers in the thickness direction.
Another notable patent involves a method for sticking an insulating film to a lead frame. This method utilizes multiple divided punches that have a clearance between them to absorb thermal expansion caused by heat from a heater. The punched insulating film is then adhered to a lead frame by being pressed between the divided punches and the heater.
