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 6480100 ,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
