    Production Overview

    Plastic Low thickness Qual Flat packaging (LQFP) is a principal package using SMD technology. It is widely used in low cost and manual applications. NFME offers LQFP (the package body thickness is 1.40mm )

    with lead counts range from 32 to 256 leads.

     

    Application

    Low thickness Quad Flat packages are considered one of the most established industry standard packages. LQFP is commonly used in memory, video ASIC, DSP, controllers, processors, gate arrays , SRAMs and PC chip sets, telecom, office equipment, disc drives and communication boards.etc

    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: 3.2mil (80um)

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