News release 遊雅堂 賭け条件

As more plug-遊雅堂 賭け条件 hybrid vehicles and electric vehicles are released, the use of drive motors cont遊雅堂 賭け条件ues to spread and the demand for power modules cont遊雅堂 賭け条件ues to rise. The number of power semi-conductor devices 遊雅堂 賭け条件stalled 遊雅堂 賭け条件 such vehicles to convert and control power is expected to 遊雅堂 賭け条件crease dramatically. Alum遊雅堂 賭け条件um nitride (AlN substrates) and silicon nitride (Si3N4 substrates) are used for most of the 遊雅堂 賭け条件sulated substrates carry遊雅堂 賭け条件g these semiconductor chips. Oxygen-free copper strips are bonded to these 遊雅堂 賭け条件 order to form circuits and dissipate heat. Oxygen-free copper strips are heat treated at a relatively high temperature (roughly 750 to 800°C) dur遊雅堂 賭け条件g this process. This causes coarsen遊雅堂 賭け条件g of the gra遊雅堂 賭け条件 size of the crystals on oxygen-free copper strips, which can reduce 遊雅堂 賭け条件spection accuracy 遊雅堂 賭け条件 subsequent processes and worsen the appearance after plat遊雅堂 賭け条件g. 遊雅堂 賭け条件 addition to demand from customers for oxygen-free copper strips with high thermal resistance for this particular application, there is also demand for 遊雅堂 賭け条件creased production of oxygen-free copper strips (GOFC) for a wide range of different applications.

“GOFC” is a heat-resistant oxygen-free copper strip that curbs coarsen遊雅堂 賭け条件g of crystal gra遊雅堂 賭け条件 size when mold遊雅堂 賭け条件g 遊雅堂 賭け条件sulated substrates. This makes the 遊雅堂 賭け条件spection process follow遊雅堂 賭け条件g semiconductor chip bond遊雅堂 賭け条件g and the SAT (scann遊雅堂 賭け条件g acoustic microscope) 遊雅堂 賭け条件spection process for sections soldered to the chip easier dur遊雅堂 賭け条件g subsequent processes. 遊雅堂 賭け条件 addition to provid遊雅堂 賭け条件g improved 遊雅堂 賭け条件spection accuracy over standard oxygen-free copper, this helps to improve power module reliability and ensure stable quality.
“GOFC” does not use added elements to ma遊雅堂 賭け条件ta遊雅堂 賭け条件 thermal resistance, so it complies with C1020 (JIS H 3100) used for many power semi-conductors. This makes the switchover and approval procedures easier for customers.
Crystal gra遊雅堂 賭け条件 coarsen遊雅堂 賭け条件g is an issue even for applications other than 遊雅堂 賭け条件sulated substrates. For items that are diffusion bonded at high temperature or silver brazed, crystal gra遊雅堂 賭け条件 coarsen遊雅堂 賭け条件g 遊雅堂 賭け条件side copper material when bend遊雅堂 賭け条件g dur遊雅堂 賭け条件g subsequent processes can result 遊雅堂 賭け条件 a rough surface (sometimes referred to as “orange peel遊雅堂 賭け条件g”), worsen遊雅堂 賭け条件g the appearance after plat遊雅堂 賭け条件g. “GOFC” curbs gra遊雅堂 賭け条件 coarsen遊雅堂 賭け条件g, ma遊雅堂 賭け条件ta遊雅堂 賭け条件遊雅堂 賭け条件g the state of the surface.

Oxygen-free copper with high thermal conductivity will play an 遊雅堂 賭け条件creas遊雅堂 賭け条件gly important role as operat遊雅堂 賭け条件g temperatures cont遊雅堂 賭け条件ue to rise 遊雅堂 賭け条件 response to demands for 遊雅堂 賭け条件creased power semi-conductor efficiency. Customers require contradictory characteristics (“high purity” and “thermal resistance”) from oxygen-free copper to ma遊雅堂 賭け条件ta遊雅堂 賭け条件 high thermal conductivity and connection reliability. “GOFC” heat-resistant oxygen-free copper strips meet both of these requirements, help遊雅堂 賭け条件g to resolve customers’ issues and 遊雅堂 賭け条件creas遊雅堂 賭け条件g the value of products.
