Due to the strongly growing consumption figures of all these packages, particularly in the automotive, telecommunication, computer, watches and smart card/RFID applications, throughput is becoming more and more an issue. In the areas low cost watches RFIDs which mostly are pure flip chip applications the market already demands flip chip shooters! This paper gives a brief overview of some applications, where high-speed mounting or even processing of advanced packages is required. The paper addresses as well the various criteria for achieving high throughputs with area array packages and bare dies for COB using advanced chip shooters.
The key criteria are the machine concept, component feeding, type of flux and adhesive application, component vision technique and PCB vision technique.
Key words: Smart Card, RFID, Flip Chip Shooter, dip fluxing, no-flow underfill
