SMTA Carolinas Changes

Fellow SMTA Members,

I would like to update you all on several important changes that have occurred recently for SMTA Carolinas. Two of our chapter officers, Larry Pymento and Cef Gonzalez, are taking on new responsibilities in their careers and are thus moving on to new challenges. They will both be missed, having led our initiatives for technical programs and membership, respectively. However, with these changes comes opportunity, and I am excited to announce several new board members. Bob Doetzer of Circuit Technology will join us as VP of Technical Programs and will be responsible for ensuring we continue to offer our membership strong technical content at future meetings. Jennifer Mace of Kimball Electronics will also join us as VP of Membership, and will lead in addition to our growth initiatives an increased focus on social media. Please join me in welcoming these individuals to the Carolinas leadership team, and as always, send us your ideas on how we can better serve you. A full list of chapter officers is available on Thank you all for your consideration.

Eddie Kobeda, Ph.D.
SMTA Carolinas President

Welcome 2017

Dear SMTA Members and Potential Members,
Thank you for the outstanding support in 2016!  
I wanted to update you on several important upcoming events in 2017.  

In just a few short weeks, we will be meeting at GMI in Mooresville to kick off the New Year with our first Info session.  Our Technical Program Director has arranged some great presentations on metrology advancements and stencil nanocoatings. In addition, our hosts will be providing a short factory tour.  

We are busy preparing for another great Expo & Technical Conference in May.  Once again, we will be at the Greensboro Airport Holiday Inn. Register early and save on your registration.  We have an outstanding speaker lineup guaranteed to clarify how the IoT revolution will change the PCBA world. If you haven’t been to our Expo recently I hope you will consider returning, we have made considerable progress this year.  In 2017, you can expect the annual golf outing and several additional info-sessions across the Carolinas. 

Your SMTA Carolinas Chapter is especially proud of the NC State University Student Chapter initiated in collaboration with Power America. Not only does this endeavor expose students to the industry, it provides our membership with a direct line to new, local talent!  As this student chapter matures, we will look for additional ways to integrate the students with future company and chapter events.

As we move through 2017, we hope to continue growing the Carolinas chapter, but we need your feedback and suggestions. Never hesitate to contact any of your chapter board members – we are here to ensure you are receiving the benefits you want from the organization. 

Thank you for your consideration and I hope to see you soon.  For additional information please contact any of our officers directly or go to

Successful Infosession GMI

Thank you to GMI and our speakers for ANOTHER great infosession and networking dinner

TOPIC: New Inspection and Metrology Advancements: Characterizing PCB Components in a New Way

The digital age has helped engineers analyze and measure critical features in new ways. By integrating hardware with software, traditional inspection and measurement limitations can be overcome. This has helped scientists and engineers acquire better data to solve complex problems with increased credibility

* How an increased depth of field makes detecting counterfeit components easier
* New ways to measure volume of deposits or component thermal expansion
* How more data points in an area format vs. single point or lines improves measurement repeatability

Speaker Bio:  Jon Tedesco recently relocated to Charlotte, NC and has been working with Keyence Corporation for more than 5 years. In his current role, he helps customers solve applications in R&D, Quality Control or Failure Analysis. Prior to Keyence, Jon worked in technical support for a Fortune 500 IT Data Center Equipment Manufacturer and holds a Bachelor of Science in Engineering Management from Clarkson University in NY.

TOPIC:  Nano coatings for stencils:  What can they do for you?

Nano Coatings have been introduced by various manufacturers, with the promise of addressing some of the challenges relative to solder paste printing. Stated benefits include:

* Reduced underside cleaning
* Reduced bridging
* Improved solder paste release
* Improvements in yield

With several Nano technologies already on the market and more likely to be introduced, how can the performance be quantified? How can an assembler approach ROI? What hidden benefits or negative impacts should be considered?  This paper will present a rigorous method for evaluating the performance and economic benefits of solder paste stencil Nano Coatings.  Criterion such as underside cleaning, bridging, solder paste deposit geometry, post-print cleaning, and abrasion resistance of the coating will all be considered.  Transfer efficiencies were studied across aperture sizes ranging using tin-lead, lead-free, water soluble, no-clean, and type 3, 4, and 5 solder pastes.  Solder paste print performance for each Nano coating was summarized with respect to all of these variables.  Performance of currently available coatings will be compared.  Standard industry rules for stencil aperture design are being challenged by nano coating, consequently, proposed guidelines for stencil design are recommended.


Speaker Bio:  Tony Lentz has worked in the electronics industry since 1994.  He worked as a process engineer at a circuit board manufacturer for 5 years.  Since 1999, Tony has worked for FCT Companies as a laboratory manager, facility manager, and most recently a field application engineer.  Since 2013, Tony has focused on field application and R&D for FCT Assembly solder and stencil products.  Tony has extensive experience doing research and development, quality control, and technical service with products used to manufacture and assemble printed circuit boards.  He has published and presented many papers at industry events.  Tony holds B.S. and M.B.S. degrees in Chemistry.

LED Component Trends for the Lighting Market
Presenter: Tom Place, CREE – MS Mechanical Engineering from NC State, he has worked at Cree for 5 years after a stint in municipal water treatment technology out of grad school. He then spent time as an engineer focused on custom samples and improving current spreading in LED chip design prior to becoming the CREE Department Manager for Package & Test R&D. Last year, he transitioned to Applications Engineering and managed the CREE Technology Center labs. Over the past 10 years, he has been playing with LEDs on a personal level, so working now with end customers on how best to use CREE LEDs is a natural fit. Well before he worked at CREE, he bought his first single high-power Cree LED, an MC-E EasyWhite for $28 from an Australian distributor to make a bike light – it is still on his desk!
Topic: Reliability of Level 1 and Level 2 Packaging in Solid-State Lighting Devices
Presenter: Lynn Davis, PhD, RTI International – Dr. J. Lynn Davis is an RTI Fellow concentrating on energy efficient lighting technologies and he currently serves as the Principal Investigator (PI) on two projects funded by the U.S. Department of Energy. One project is developing reliability models and accelerated life test methods for the optical and electrical aspects of Solid-State Lighting (SSL) devices, and the other is developing low-cost high efficiency color tunable light sources for educational markets. Before joining RTI, Dr. Davis spent 12 years in a variety of technical and managerial roles at Motorola, Inc., including materials engineer supporting radio and cell phone manufacturing lines; technical advisor to Motorola Ventures (investing arm of Motorola); research manager for both advanced manufacturing technologies and energy technology.  Dr. Davis also served as the chairman of the Energy Systems Group Patent Committee. He is the recipient of more than 50 U.S. patents and has published more than 50 peer reviewed articles.

“Fill the Void" by Tony Lentz, FCT Assembly

Voids in solder joints are a concern for many electronic manufacturers. Minimization of voiding is beneficial for the life and function of the circuit board; yet, many things cause voids. Regardless of the cause, there are ways to minimize voiding. For example, changes to the reflow profile can help reduce voiding, but the changes need to fit the solder paste. A test was designed to validate methods of minimizing voiding and a set of recommendations were made. This was all done in an effort to help the reader to “Fill the Void”.  

"Optimize the Reflow Profile to Minimize Voiding" by Marybeth Allen, K.I.C. 
Void reduction is a significant concern and controversial topics in electronics assembly. Voiding impacts electrical, thermal, and mechanical performance. There are many variables such as substrates, components, solder paste, acceptable void levels, and of course the reflow profile. This discussion will focus on the optimization of the reflow profile as one the solutions for the reduction of voiding.

Chapter Update & Elections


Hello Current and Future SMTA Members,

I wanted to take a few moments to update you on several important topics as we enter the fall and approach the end of 2016. I hope many of you have had a chance to participate in one of our technical sessions hosted by the Carolinas Chapter, or utilized the resources on our SMTA web site provided by our national organization. Remember there continues to be excellent offerings with respect to webinars, papers, etc. from leading industry experts which will enhance your career and provide a great balance of business and technical acumen.

We have several important events coming up soon, including a golf outing this Thursday, Sept. 15, a joint SMTA – Student Chapter meeting at Juki in RTP, NC, on Thursday Sept. 22, and of course SMTAi is right around the corner the week of Sept. 26 in the Chicago area. We are also planning for an additional Info Session Dec. 8 at Cree in Durham, NC. Please mark your calendars and consider joining us for any or all of these events. There is still plenty of time to sign up.

Another important issue I want to highlight are the annual elections which are just around the corner (typically completed in Oct./Nov. time frame). I would like to encourage everyone to consider how they might participate further in SMTA, or perhaps nominate a colleague who could bring their unique and valuable leadership experience to the organization. We all realize the many challenges this can invite but are excited about the possibilities, especially the creative ideas we would expect from new faces. Of course, your role could simply be in the form of a collaboration on a small project or it could be a very big new role that benefits our members and the chapter objectives more widely. I hope you will give this further thought and let any of our current officers know if you have any questions.

For the many of you that are already members let me thank you sincerely for your continued support. If you are not currently a member I strongly encourage you to consider joining the Carolinas Chapter, and prior to that please allow one of our officers to share their own personal stories on the benefits of participating. Thank you very much for your consideration.

Eddie Kobeda, Ph.D.
President, SMTA Carolinas Chapter
