ASE's Embedded (Chip) Technology is considered an alternative solution to achieve higher level integration with multi-functionalities and form factor shrinkage advantages. ASE a-EASI is suitable for power electronics applications to reduce power loss and high thermal dissipation which also had robust mechanism. Embedded Technology provides SMT integration and flexible routing solution to reduce PCB size. The short connection path though Cu via structure. a-EASI applied metal lead frame to die placement which has high thermal dissipation and EMI benefit.
