Advantages of Ultrasonic Flip Chip Bonding against Lead/Adhesive Process
In comparison to other flip chip processes the ultrasonic process allows a four to five times higher contact density. Only one process step is needed for the chip attach. This process guarantees extremely high mechanic stability and termal strength for the connections. It is a so called "clean process" (no adhesive, monometallic connections, leadfree process).
