Cleaning and Reliability Workshop

O V E R V I E W

Over the past twenty years, the electronic manufacturing industry has seen cleaning (defluxing) become more necessary and more challenging. Never before, has the removal of contamination from circuit assemblies been so important to a product's overall reliability. Increasing component and assembly densities, decreasing standoff heights, higher reflow temperatures, and increased reliability expectations have created a "perfect storm" that is driving manufacturers to seek cleaning solutions.

Experts from soldering materials, cleaning chemicals, cleaning and conformal coating equipment, and failure analysis companies will present valuable and technically relevant information.

Join us in Huntsville Alabama for a free one-day Cleaning and Reliability workshop. Five industry experts from Aqueous Technologies, Henkel, Kyzen, PVA, and STI Electronics join forces to present valuable solutions to today's most challenging cleaning and reliability issues.

This free workshop will be presented free of charge and lunch will be provided. Seating is limited so reserve your seat today.

Cleaning & Reliability Workshop

Once commonplace, the process of removing flux and other contamination from post-reflow circuit assemblies virtually disappeared in the latter part of the 20th century. Cleaning was replaced by the use of no-clean flux and the residues were commonly allowed to remain on the assembly.

Today, component and assembly miniaturization, higher temperature reflow profiles, and increased reliability expectations have combined to reduce the volume of allowable contamination acceptable on an electronic assembly. The removal of flux and other process residues and cleanliness testing are among the fastest growing yet least understood processes in electronic assembly industry today.

This one-day technical workshop will answer many common questions about cleaning, cleanliness testing, conformal coating, failure analysis, and other reliability related topics.

The workshop is free and seats are limited. A continental breakfast and lunch will be provided.

September 13, 2012

8:30 - 9:00	Registration and Breakfast
9:00 – 9:15	Welcome & Introduction: Present background on speakers and review the agenda for the day.
9:15 – 10:15	Michael Konrad - Aqueous Technologies "Electrical Leakage, Dendritic Growth, and White Residue...The Rush to Clean No-Clean" Abstract: Once commonplace, then relegated to military and other high reliability applications, today, defluxing has once again moved toward the mainstream. The miniaturization of electronic assemblies and their components, implementation of lead-free alloys, combined with improved quality standards and higher reliability expectations have culminated to form a growing demand for ionicly clean electronic circuits. This paper will review the major causes of residue-related failures including dendritic growth, electrical leakage, and under-coating adhesion failures. Why we clean and what we are removing, and how clean is clean will be presented. A cleaning equipment “roadmap” will be presented and will review various cleaning processes, modern equipment requirements, and environmental considerations.
10:15 – 10:30	Break
10:30 – 11:30	Dave Edwards – Henkel "Cleaning of No-clean & Water Soluble Solder Pastes, and Compatibility of Underfills / Conformal Coatings to Solder Flux Residues"
11:30 – 12:30	Lunch
12:30 - 1:30	Tom Forsythe - Kyzen Corporation "Cleaning technology Innovations Needed to Clean Highly Dense Assemblies" Abstract: As highly dense circuit assemblies continue to advance at a rapid pace, the removal of process residues is ever more necessary. Low residue no-clean residues did not require cleaning on assemblies with larger spacing between conductors. As the distance between conductors narrow, residues under component gaps pose a reliability risk. Additionally, the transition to lead-free alloys with tighter component densities requires flux residue innovations that can withstand higher reflow temperatures. Traditional cleaning agents and cleaning equipment may not be able to remove these harder to clean flux residues from extremely small geometries.Increased circuit functionality is accomplished using bottom termination surface mount components. As components reduce in size, the distance from the board to the underside of the component reduces. Flux residues bridge conductors making cleaning highly difficult. One of the most challenging issues is the selection of an appropriate cleaning process that will clean flux residues under these extremely tight geometries. Cleaning agents must be designed to remove strong covalent (hydrophobic) and weak ion (hydrophilic) bonds. Cleaning machines must be designed to move the cleaning agent to the source of the residue and either extract or create a flow channel to remove residues under component gaps. Recent solvent and aqueous cleaning agent and cleaning equipment innovations have been developed to bridge this gap. To achieve the process objective, cleaning agent and cleaning equipment suppliers collaborate with assemblers to develop improved cleaning processes.
1:30 - 2:30	Jon Urquhart, PVA "Modern Conformal Coating – Equipment & Techniques” Discussions include how the coating process and equipment has evolved from hand and bulk spray automation to programmable automated equipment. Also included is a discussion on the latest advancements in machines, coatings, and processes.
