Pad cratering is defined as cracking which initiates within the laminate during a dynamic mechanical event such as In Circuit Testing (ICT), board depanelization, connector insertion, and other shock and vibration inducing activities.
Simulation can be used to prevent this serious but prevalent failure. Pad cratering was first recognized in BGA packages but newer leadless, bottom termination components are also vulnerable.

Physics of Failure Simulation and Modeling Specification WebinarEd Dodd
This document discusses specifying and satisfying physics of failure requirements for product reliability. It covers topics like defining the use environment, reliability expectations, thermal and mechanical stresses, and communicating reliability needs throughout development. Accuracy and precision in reliability analysis must be balanced with cost. Thermal, vibration, and shock stresses are important to consider and can be analyzed using tools and models. The goal is to predict time to failure of components under combined operating conditions.
MTBF is a common metric among practitioners and users of reliability prediction, safety assurance, and maintenance planning. However, there are a number of significant flaws and limitations with this approach. This presentation goes through those limitations and uses that information to suggest alternatives that may provide much greater insight into product performance.
Design for Manufacturing: Challenges & OpportunitiesCheryl Tulkoff
In the electronics industry. the quality and reliability of any product is highly dependent upon the capability of the manufacturing supplier, regardless of whether it is a contractor or a captured shop. Manufacturing issues are one of the top reasons that companies fail to meet warranty expectations, which can result in severe financial pain and eventual loss of market share. What a surprising number of engineers and managers fail to realize is that focusing on processes addresses only part of the issue. Design plays a critical role in the success or failure of manufacturing and assembly.
Designing printed boards today is more difficult than ever before because of the increased lead free process temperature requirements and associated changes required in manufacturing. Not only has the density of the electronic assembly increased, but many changes are taking place throughout the entire supply chain regarding the use of hazardous materials and the requirements for recycling. Much of the change is due to the European Union (EU) Directives regarding these issues. The RoHS and REACH directives have caused many suppliers to the industry to rethink their materials and processes. Thus, everyone designing or producing electronics has been or will be affected.
This presentation provides a comprehensive insight into the areas where design plays an important role in the manufacturing process. This workshop addresses the increasingly sophisticated PCB fabrication technologies and processes.
As wearable electronics become increasingly important to our daily lives, it is important that designers, suppliers, manufacturers, and users understand the 'special sauce' that will make this new technology sufficiently robust and reliable for the marketplace
The document discusses a software tool called Sherlock that uses simplified component models to rapidly assess interconnect reliability in electronics.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
