Abstract - Cleaning Before Conformal Coating 
Do you conformally coat your electronic assemblies? If so, cleaning prior to conformal coating is a must to ensure the long-term reliability of your products. This webinar provides an overview of potential failure mechanisms resulting from coating over residues.

Abstract - pH Neutral vs Alkaline Cleaning Agents
Although modern aqueous alkaline cleaning agents effectively remove flux residues, achieving satisfactory results often requires an increase in temperature, exposure time, chemical concentration, and mechanical energy resulting in material compatibility issues. This webinar presents data from three case studies detailing how newly developed pH neutral formulations have proven to be capable of removing difficult post reflow residues from complex board geometries without affecting material compatibility of sensitive components.

The SMTA Capital Chapter to Host a Meeting on November 7th at ZESTRON Americas

October 3, 2017 - The SMTA Capital Chapter is pleased to announce its third meeting of 2017 on November 7th, scheduled from 5:30 pm to 8:00 pm at ZESTRON Americas, 11285 Assett Loop, Manassas, VA, 20109. Ravi Parthasarathy, Senior Application Engineer, ZESTRON Americas, will present “Cleaning Before Conformal Coating” and “pH Neutral Cleaning Agents - Market Expectation and Field Performance”.
 
Cleaning Before Conformal Coating - Do you conformally coat your electronic assemblies? If so, cleaning prior to conformal coating is a must to ensure the long-term reliability of your products. This webinar provides an overview of potential failure mechanisms resulting from coating over residues.
 
pH neutral Cleaning Agents – Market Expectation & Field Performance - With regard to precision cleaning applications within electronics manufacturing, pH neutral product development was a major breakthrough in recent years. The impetus for this development resulted from changes with regard to solder paste formulations and resulting assembly processes.
 
The greater use of lead-free solder paste and the required higher reflow profiles have resulted in even more difficult to remove burnt-in flux residues. Coupled with increases in component density, larger component packages, higher lead counts, finer lead spacing, and lower standoff distances, effective cleaning is greatly challenged. The aqueous alkaline based cleaning agents can effectively remove these flux residues, however, the process often requires an increase in wash temperature and exposure time, chemical concentration, and mechanical energy. Although an efficient and effective cleaning process can be developed, oftentimes, the required operating parameters present a new set of challenges with regard to material compatibility.
 
Since their introduction, the newly developed pH neutral formulations have proven to be capable not only of removing these difficult post reflow residues from complex board geometries, but do so without affecting material compatibility of sensitive components. Additionally, they perform at low concentration levels. This study reviews the performance of pH neutral cleaning agents as compared to alkaline cleaning agent alternatives and includes field data demonstrating their effectiveness with regard to material compatibility and cleaning performance.

Shannan O’Shaughnessy, GVD Corporation, to Present at SMTA Capital Chapter’s Expo and Tech Forum

 August 11, 2017 - The SMTA Capital Chapter is pleased to announce that Shannan O’Shaughnessy of GVD Corporation, will present “Reliability without Hermeticity: Commercial Vapor Deposited Coatings for High-Frequency RF Micro-Electronics” at the upcoming Capital Expo and Tech Forum at Johns Hopkins University / Applied Physics Lab, Kossiakoff Center, on Thursday, August 24th.  
 
Radio frequency (RF) micro-electronics are used everywhere in today’s technology, from the internet of things to military radar systems. It is challenging for these advanced RF systems to meet size, weight, power and cost requirements set by consumer market or defense agency demand, what the military calls “SWaP-C”, due to the need for packaging of the RF components and integrated circuits (ICs) in to ensure long term reliability. Reliability concerns traditionally necessitate the environmental protection of these high-frequency RF devices at either the component or the assembly level by hermetically sealing the device in a bulky, heavy expensive metal enclosure to prevent degradation caused by hazards in device operating environments. Industry standard conformal coatings are unusable due to the significant signal degradation which occurs if applied directly over an RF circuit. There is a critical need for a coating alternative to which is compatible with high-frequency RF devices to provide a lower weight and lower volume environmental protection scheme with high reliability and negligible performance impact for RF devices. This approach would allow RF device integration on size, weight, and cost effective PCBs and eliminate the hermetically packaged chip-and-wire assemblies currently in use. To address this need, GVD Corporation has developed a high reliability environmental coating, Exilis, for RF electronics devices that can be applied to both the bare device and completed assemblies. 
 
The SMTA Capital Expo and Tech Forum will be held at Johns Hopkins University / Applied Physics Lab, Kossiakoff Center, 11100 Johns Hopkins Road, Laurel, MD 20723. Registration opens at 8:00 AM and includes a complimentary lunch on the show floor.  Exhibits are open from 9:00 AM until 3:00 PM and the first technical presentation will start at 9:30 AM.

Phil Zarrow, ITM Consulting, to Present at SMTA Capital Chapter’s Expo and Tech Forum on August 24th

July 27, 2017 - The SMTA Capital Chapter is pleased to announce that Phil Zarrow of ITM Consulting, will present “The ‘Deadly Sins’ of SMT Assembly” at the upcoming Capital Expo and Tech Forum at Johns Hopkins University / Applied Physics Lab, Kossiakoff Center, on Thursday, August 24th.  
 
Everyone has heard of the “7 Deadly Sins” that will, supposedly, lead one to Hell. There are also the “Deadly Sins” of SMT - there are more than just 7 – and they can make your assembly process a “hell on earth”.
 
During the course of ITM’s assembly process audits and troubleshooting work, we tend to see trends in the types of errors and problems. In other words, a lot of people are making the same mistakes. The resulting process problems wreak havoc with an impact on assembly yields ranging from 5 to 20%. In addition to this direct cost, there is also additional financial impact with regard to time spent reworking and repairing, the on corrective action by QC, Engineering and Management, and, of course, “do-over”.
 
This presentation identifies the “deadly sins” of SMT assembly, both for Pb-free and “leaded” processes. Besides the symptoms and consequences of each type of error, root-cause, rectification and prevention techniques will be presented. Best Practices will be discussed for each of the key process steps. The workshop will, thus, provide the participant with an understanding of how to identify and correct the most common SMT assembly problems. It will include identification of vendor and source problems including components and materials as well as design related problems.
 
The SMTA Capital Expo and Tech Forum will be held at Johns Hopkins University / Applied Physics Lab, Kossiakoff Center, 11100 Johns Hopkins Road, Laurel, MD 20723. Registration opens at 8:00 AM and includes a complimentary lunch on the show floor.  Exhibits are open from 9:00 AM until 3:00 PM and the first technical presentation will start at 9:30 AM.

Second Meeting of 2017 - April 25 at ZESTRON Americas

Presentations at the second meeting of the year for the SMTA Capital Chapter held at ZESTRON Americas included:

Dr. Gil Sharon, DfR Solutions, presented “Effective Use of Reliability Simulation in an Agile Development Process”.

The use of simulation to predict reliability early in development is increasing as more electronic equipment manufacturers migrate to an Agile Methodology. However, most companies struggle to incorporate simulation and modeling successfully into new product introduction. This presentation will outline industry best practices in regards to the timing and workflow for the integration of reliability simulation and modeling. The audience will be introduced to process flows appropriate for component selection, pre-layout and post-layout activities. The type and timing of data transfer will be discussed and how it can be adjusted for different corporate structures. Case studies relevant to Solid State Drives (rigorous requirements for temp cycle, shock and vibration), Internet of Things (small form factor, state-of-the-art wireless, uncontrolled environments), and rapid implementation of Advanced Packaging (small pitch, large die, 3D) into Automotive and Military applications will be presented. There is a specific focus on the value of iteration and tradeoff studies generated by an integrated reliability simulation.

Naveen Ravindran, ZESTRON Americas, presented “High-Reliable Cleaning Process Optimization & Customer Requirements”.

Product quality is vital to manufacturing products that meet the customer’s reliability standards. However, when new customer requirements cannot be met, line deficiencies must be identified and corrected. Mr. Ravindran will provide details on how a properly designed experiment unveiled the solutions to a customer’s cleaning challenges and identified a way to increase product quality while decreasing operating costs.
