Data Sheet LEADFRAME MicroLeadFrame® MLF®/QFN/SON/DFN MicroLeadFrame® Quad Flat No-Lead Package (MLF®/QFN/SON/DFN) Amkor's MicroLeadFrame® QFN package is a near CSP plastic encapsulated package with a copper leadframe substrate. This package uses perimeter lands on the bottom of the package to provide electrical contact to the PWB. The package also offers Amkor's ExposedPad technology as a thermal enhancement. Having the die attach paddle exposed on the bottom of the package surface provides an efficient heat path when soldered directly to the PWB. This enhancement also enables stable ground by use of down bonds or by electrical connection through a conductive die attach material. MLF Offerings • • • • • • • • • • • • Chip-on-Lead (COL) Single Row (Up to 108 I/O) Dual Row (Up to 180 I/O) Multi Chip Package Non-Exposed Pad PPF (NiPd) Punch & Saw MLF Small MLF (Less than 2 x 2 body size) Stacked Die Thin MicroLeadFrame® Top Exposed Pad (TEP) Inframe Cavity MLF Flipchip MLF Dual Row MLF Package An MLF package with two rows of leads offers a cost effective, high performance solution for devices requiring up to 180 I/O. Typical applications include hard disk drives, USB controllers and wireless LAN. Visit Amkor Technology online for locations and to view the most current product information. Saw MLF PEL (Plated End Lead) Package Customer demand for Fine lead pitch (0.50 mm, 0.65 mm) is needed in the automotive Industry. Higher solder fillet height on the side of lead area; similar or better BLR performance than standard design; no need of X-ray monitoring after SMD. This process is released to HVM (High Volume Manufacturing). FAM (Film Assist Mold) MLF Package Better release-ability which enables complicated mold structures like cavityopen packages (Seal film); Protection on brittle surface of die and glass lids from mechanical impact by cavity insert on mold chase (seal film); resin/mold flash control (adhesive film). PQFN (Power) MLF Package To qualify FET (Field Effect Transistor) devices in QFN package using solder paste and copper clip; layout and packaging use copper connections for all power paths rather than wire bonds, reducing losses due to high resistance wire bonds as well as high inductance which cause ringing and high AC losses. RtMLF (Routable Molded Lead Frame) Package An MLF® package with resin filled traces for small form factor driven structures. This offers a low cost, high thermal performance device in a smaller foot print. It has internal routing traces with limited line width/space capability and this package adapts easily to flipchip configurations. rtMLF provides higher pin count and more flexible internal trace routing with resin filled LF. It enable small form factor, high electrical/thermal performance with low cost. DS572Q Rev Date: 10/15 Questions?
