Tackling Packaging Challenges:

With the adoption of SiC and GaN comes a new set of challenges. These materials demand better thermal management, electrical connections, and mechanical stability.

Think of it like upgrading from a basic toolbox to a high-tech workshop—you need the right tools and techniques to handle the job.

That’s where innovations like direct bond copper and embedded substrate approaches come in, providing better heat dissipation and reducing electrical resistance.

Exploring Diverse Package Types:

Power electronics packaging comes in all shapes and sizes, each suited to different applications.

From discrete packages like TO-247 and TO-220 for specific power needs to surface-mount devices. It is like D2PAK and PQFN for space-constrained designs, there’s a packaging solution for every situation.

It’s like choosing the right outfit for the occasion—sometimes you need something formal, sometimes casual, but it always has to fit just right.
