Alpha and Omega Semiconductor Introduces New RigidCSP™ Technology for Battery Management Applications
23 July 2020 - 10:00PM
Business Wire
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL) a
designer, developer, and global supplier of a broad range of power
semiconductors and power ICs, today announced the release of
RigidCSP™ for battery management. Alpha and Omega Semiconductor has
developed a RigidCSP technology where you can decrease the
on-resistance while increasing the mechanical strength to reduce
breakage during assembly and stress during the lifetime of the
battery MOSFET. The new package technology is ideal for
applications such as smartphones, tablets, and ultra-thin
notebooks.

Management Applications (Graphic: Business Wire)
As requirements increase for higher charging current, then
ultra-low electrical resistance is needed for improved performance.
In standard WL- CSP, the substrate can be a significant portion of
the total resistance on the back-to-back MOSFETs. A thinner
substrate will reduce the overall resistance but also will
drastically reduce the mechanical strength. This reduction of
mechanical strength can lead to more stress during the PCB assembly
reflow process, which can lead to die warpage or die crack, which
leads to failure in the application.
“Using RigidCSP technology offers performance improvement with
high robustness. RigidCSP can be used for high aspect ratio CSP die
size, and RigidCSP can enable an overall reduction in
warpage/breakage from assembly board manufacturing,” said Peter H.
Wilson, Marketing Director of MOSFET product line at AOS.
