ATXWH is a globally significant manufacturer of discrete device assembly and test services, specializing in the packaging and testing of power semiconductor devices. Its main products include over 50 packaging forms such as the full TO Power series, SOT/SC series, and DFN series, covering MOSFET, IGBT, SiC, GaN, and other products, with an annual production capacity of 5.7 billion units. These products are widely used in electric vehicles, industrial control, automotive electronics, renewable energy (such as photovoltaics), household appliances, consumer electronics, and other fields. In particular, it holds a high market share in the field of international brand electric vehicle controllers.
Gallium-Nitride (GaN) has several advantages over Silicon when it comes to applications in the field of power semiconductor.
GaN- based power devices have an estimated of 10-100 times faster switching characteristic as compared with Silicon-based devices. This makes the GaN assembly as one of the desirable technology that can enable the highest-performance, smallest and most cost effective RF modules.
ATX has engaged into several GaN assemblies, including the use of the highest thermal Silver Sintering epoxy, that can deliver more than 200W/mK of thermal conduction capability.
ATX has developed GaN packaging several solutions to address the fast growing needs of RF infrastructure into QFN and DFN package, including the use of 20mil leadrame thickness.
ATX portfolio of Power Module has the integration of several inductors, FETs, and other passive components into a single package solution which being driven at 4mm mold body thickness. It covers all aspect of packaging solutions including Laminate (BGA and LGA) and leadframe based packages. For Open Cavity configuration includes the flip chip dice and passive component underneath the huge inductor as well as side by side options.
ATX engineering approach in using Compression molding process instead of the transfer mold has gained several advantages such as elimination of voids due to the mold flow issue. Benefits in increase strip panel utilization enables lower assembly cost as this solution has allowed ATX to use single panel strip configurations.
Intelligent Power Module or IPM is an integration of power switches and gate drivers to form a high performance module. It also composes of customs ICs with main function of self-protection in terms of short circuits, under voltage supplies, and over temperature.
ATX has initiates to venture to IPM as additional Power Module portfolio, integration of several IGBTs, diodes, PCBs, and other power ICs to complete an Intelligent Power Module for industrial and commercial applications.
IPM encapsulation involves both plastic and ceramic options. Though transfer mold will be the main solution, Gel encapsulation will also be an option as well.
Cu Clip is the most desirable replacement of wirebond for high performance MOSFETS and other power devices.
Cu clip is highly being implemented in discrete products, as main target application belongs to industrial, telecommunication infrastructure, mobile computers, and automotive.
ATX Weihai, a dedicated facility for Cu Clip has a vast and extensive experience in volume production. Its facility has been constantly expanding its capacity to address growing demands from its customers especially in the field of automotive electrifications.
