Alloy Spacer
PA-800A01

Alloy Spacer is a metal spacer for interconnection on the front‑side active surface of power chips. It can replace conventional aluminum bonding. Featuring high current‑carrying density, excellent temperature uniformity, outstanding thermal conductivity and zero residue after soldering, it serves as the core structural component of double‑side cooling (DSC) wire‑free power modules.
