A TSSOP (thin-shrink small outline package) is a rectangular, thin body
size surface mount component. A Type I
TSSOP has leads protruding from the width portion of the package. A Type II
TSSOP has the leads protruding from the length portion of the package. With the evolution of smaller, denser, faster and lighter end products, Amkor not only shrunk the SOP by decreasing the lead pitch, but also made it thin - 0.9 mm thin! Amkor invested time and research into assuring quality and reliability with advanced designs, assembly equipment / processes and materials. The result is controlled package flatness wire sweep, solderability and delamination resistance.
Amkor now makes it possible for IC designers, packaging engineers, circuit designers and component specifiers to work concurrently and succeed with its TSSOP product line.
These IC packages are particularly suited for gate drivers, controllers, wireless / RF, op amps, logic, analog, ASICs, memory (EPROM, E2PROM), comparators and optoelectronics. Memory modules, disk drives, recordable optical disks, telephone handsets, speed dialers, video / audio and consumer electronics / appliances are suggested uses for TSSOP packaging.
