Product Overview

AuSn preform aluminum nitride (AlN) substrates with TFC (Thin Film Circuit) technology are high-end ceramic circuit solutions designed for optical communication and photonics packaging.

The integration of pre-deposited AuSn (gold-tin) solder layers enables high-reliability, void-free die attachment, while the AlN ceramic base provides excellent thermal conductivity. TFC technology ensures ultra-fine circuit patterns and superior electrical performance, making these substrates ideal for high-frequency and high-precision optical devices.
