The document discusses different types of conformal coatings, their properties and applications. It defines conformal coating as a thin protective plastic film that conforms to an electronic circuit board. The main types covered are acrylics, polyurethanes, epoxies, silicones and fluorocarbons. Acrylics are most common due to their low cost and ease of application, while silicones are suitable for high temperature uses. Key factors in selecting a coating include chemical resistance, temperature tolerance, and ease of application and repair.
Conformal Coating is applied to circuit cards to provide a dielectric layer on an electronic board. This layer functions as a membrane between the board and the environment. With this coating in place, the circuit card can withstand more moisture by increasing the surface resistance or surface insulation resistance (SIR). With a higher SIR board, the risk of problems such as cross talk, electrical leakage, intermittent signal losses, and shorting is reduced.
This reduction in moisture will also help to reduce metallic growth called dendrites and corrosion or oxidation. Conformal coating will also serve to shield a circuit card from dust, dirt and pollutants that can carry moisture and may be acidic or alkaline.
There are several types of conformal coating materials and the selection of one for your application must consider several variables. Silicones, polyurethanes, acrylics, epoxies and some of the newer hydrophilic materials offer many options to the user. However, the incorrect selection can result in huge problems with your CCA. For example, if you use silicone as your conformal coating material in a high sulfur environment, the silicone absorbs the sulfur and enhances the probability of silver migration on chip resistors and other forms of corrosion.
The Effect of Coating and Potting on the Reliability of QFN DevicesCheryl Tulkoff
The lack of a compliant lead structure makes QFN devices more susceptible to PCB warpage related failures:
oMechanical properties of the potting material
oGlass transition temperature (Tg)
oModulus should be specified above and below the Tg
oCTE should be specified above and below the Tg
The design of the housing:
oMay provide a surface to which the potting material can pull against when shrinking causing PCB warpage
oShould be designed to provide as close to a hydrostatic pressure as possible (equal pressure on all sides)
Corrosion monitoring in petroleum refineriesK R SONI
In petroleum refineries, corrosion of equipment takes place all through its operating life. It is essential to monitor the corrosion damage so that timely corrective actions like maintenance / repairs / rehabilitation of equipment can be undertaken before it causes unsafe plant operations.
The techniques employed for systematic corrosion monitoring of refinery equipment have been described in this presentation.

A Systematic Approach to Hygrothermal Modeling and Compliance with Failure Cr...pmantha
Simulating the prediction of moisture movement and related risk within building envelopes has gained momentum with the increased use of thicker walls, new
materials and assemblies. One such simulation software used widely across North America for hygrothermal analysis is WUFI 5.1. As with any other simulator,
WUFI 5.1 requires a few basic inputs such as location, orientation, climate and construction. But hygrothermal modeling is not a clear-cut task. The interactions
between the macro level inputs and the dependency on molecular make-up and characteristics of materials makes prediction of hygrothermal performance very
volatile. This volatility could lead to under or over predicting moisture related risk in building elements.
As a part of an ongoing research and monitoring project, the authors’ team evaluated and intends to monitor several different configurations of wall
assemblies in multiple climate and moisture zones to determine the accuracy of moisture modeling. The goal is to make recommendations to ensure durable, efficient
assemblies. Based on this research, this paper presents a systematic approach to hygrothermal modeling with WUFI 5.1. Methods to determine compliance with
existing failure criteria using results from WUFI 5.1 are discussed. General software observations and possible future improvements are suggested

The main intention is to protect the sensitive electronic components during the molding stress, because high pressure molding would harm the properties of these components. Additionally, low pressure seal molding also protects electronic components against dust, moisture and vibration stress. It is also commonly used for Cable relief and sealing connectors.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
