DESCRIPTION

STATS ChipPAC’s Quad Flat No-Lead (QFN) and Dual Flat

No-Lead (DFN) package offering includes the QFNs (saw

singulated), QFNp (punch singulated), XQFN, UQFN, WQFN,

and QFN-dr. These are leadframe based, plastic encapsulated,

chip scale packages in single mold cavity format (punch

singulated) or molded array format (saw singulated).

An exposed die pad coupled with extremely low RLC

provides excellent electrical and thermal performance

enhancements which are ideal for high frequency and high

power applications, and are especially suited for wireless

and handheld portable applications such as cell phones.

QFN-dr with staggered dual row leads offers higher I/O

counts. STATS ChipPAC’s QFN packages are currently

available in various body sizes and thicknesses, offered in

standard and green/lead-free bill of materials and can be

processed by conventional SMT equipment, benefiting

surface mount operations downstream.

APPLICATIONS

•RF

• Power management

• Discretes

• Analog/Linear

• Logic

• Applications requiring enhanced electrical and thermal

performance and reduced package size, thickness and

weight
