    Production Overview

    Plastic  Quad  Flat packaging (QFP) is a principal package using SMD technology. It is widely used in low cost and manual applications. NFME offers QFP (the package body thickness is 2.75mm )

    with lead counts 64,80,100 ,128leads.

     

    Application

    Quad Flat packages are considered one of the most established industry standard packages. QFP is commonly used logic, memory, and micro-controllers.  found in applications such as automotive consumer and communications products.

     

    Features

    * JEDEC standard compliant or reference
    * Wide choice of pad sizes to meet die size per customer lead frame design capability
    * Pb-free process ready and Green Molding Compound

     

    Design Rule

     

    Minimum Ink Size: 20mil (500 um) diameter or non-ink with wafer mapping

     Maximum Ink Height: 1mil(25um)

    Minimum Sawing street width: 2.4mil (60um)

     

    Wafer Thickness: Back grinding is required if the thickness exceeds NFME spec.
