Latest Patents
Ibaraki's latest patents include a method for producing a metal/ceramic bonding circuit board. This innovative method allows for the formation of fine patterns even when using a thick circuit forming metal plate. It also shortens the etching time required for production. The process involves causing molten metal to contact a ceramic substrate, which cools and solidifies to bond the circuit forming metal plate to the ceramic substrate. This results in a metal circuit plate with a desired circuit pattern.
Another significant patent is for a metal/ceramic bonding substrate that prevents warping during soldering. In this design, a metal circuit plate is bonded to one side of a ceramic substrate, while a heat sink plate is bonded to the other side. A work-hardened layer is formed on the heat sink plate through shot peening. This substrate allows for the soldering of semiconductor chips and the production of a power module, enhancing the overall efficiency of electronic devices.
