Anyone facing QFN package crack problem ?

Electronics Forum | Tue Nov 27 20:51:18 EST 2007 | chs

Anyone can share experience on package crack for QFN package. This package is so sensitive to any external force. Any good recomendation on desoldering / rework procedure.

Guidelines for Design and Assembly Process Implementation for Bottom Termination Components Released by IPC

Industry News | 2011-05-03 22:50:52.0

Assemblers who have tried to resolve problems that stem from the rapidly growing array of advanced packages are getting some help from IPC with the newly released IPC-7093, Design and Assembly Process Implementation for Bottom Termination Components. This standard describes the critical design, assembly, inspection, repair, and reliability issues associated with bottom termination components (BTCs) whose external connections consist of metallized terminals that are an integral part of the component body.

Characterize and Understand Functional Performance Of Cleaning QFN Packages on PCB Assemblies

Technical Library | 2022-12-19 18:59:51.0

Material and Process Characterization studies can be used to quantify the harmful effects that might arise from solder flux and other process residues left on external surfaces after soldering. Residues present on an electronic assembly can cause unwanted electrochemical reactions leading to intermittent performance and total failure. Components with terminations that extend underneath the package can trap flux residue. These bottom terminated components are flush with the bottom of the device and can have small solderable terminations located along the perimeter sides of the package. The clearance between power and ground render high electrical forces, which can propagate electrochemical interactions when exposed to atmospheric moisture (harsh environments). The purpose of this research is to predict and understand the functional performance of residues present under single row QFN component packages. The objective of the research study is to develop and collect a set of guidelines for understanding the relationship between ionic contamination and electrical performance of a BTC component when exposed to atmospheric moisture and the trade-offs between electrical, ionic contamination levels, and cleanliness. Utilizing the knowledge gained from undertaking the testing of QFN components and associated DOE, the team will establish a reference Test Suite and Test Spec for cleanliness.

NSOP Reduction for QFN RFIC Packages

Technical Library | 2017-08-31 13:43:48.0

Wire bonded packages using conventional copper leadframe have been used in industry for quite some time. The growth of portable and wireless products is driving the miniaturization of packages resulting in the development of many types of thin form factor packages and cost effective assembly processes. Proper optimization of wire bond parameters and machine settings are essential for good yields. Wire bond process can generate a variety of defects such as lifted bond, cracked metallization, poor intermetallic etc. NSOP – non-stick on pad is a defect in wire bonding which can affect front end assembly yields. In this condition, the imprint of the bond is left on the bond pad without the wire being attached. NSOP failures are costly as the entire device is rejected if there is one such failure on any bond pad. The paper presents some of the failure modes observed and the efforts to address NSOP reduction
