For products that carry large currents, "thick copper boards" with significantly thicker circuit patterns are useful. For example, it can be used for applications that require large currents that cannot be handled with regular printed circuit boards, such as rechargeable batteries used in solar power generation and ECUs for high-power motors in electric vehicles.
■Characteristics of thick copper substrate
・Circuit formation with conductor thickness of 175 to 210 μm
・Supports large current 100 to 180A
■Main uses
・EV charger
・In-vehicle DC/DC converter
