Alpha Assembly Solutions on Training, Education, and Low-Temperature Soldering

Matties: Densities also increase, of course. How does that complicate the process?

Fullerton: We want smaller chips to do more and dissipate more heat. Heat is one of the times when voiding can be a reliability concern. Many devices use a thermal plane on the bottom as their thermal interface material between the chip and the heat sink, which is the board. Voids in the material will undoubtedly reduce the thermal conductivity, but there is not a good understanding of what is the critical level. Is 10% or 20% good enough? How about 50%? No one knows the real number, so since we can measure it and we know that more must be bad, we strive towards less, but no one knows where that finish line is. We want to see increasingly less, even though continually driving down that number may not provide as many benefits as people think it does.

Matties: It becomes a diminishing return.

Fullerton: Correct.

Happy Holden: It's interesting because when you're telling us about companies hiring new engineers and expecting them to know all these practical elements, the same is true for printed circuit design and fabrication. Electrical engineers don't know how to design a PCB. They know all about Maxwell's equation and signal integrity but without any kind of hands-on experience. Do we need to rethink four-year degree programs and start focusing on offering four-year technology degrees where you don't have theoretical math and science classes, but more hands-on design and assembly so engineering graduates can start knowing a lot more about the real world in practical electronics? It costs your company money to train these people, and somebody has to pay for that. It probably comes out of your profits or your prices. A company that offers no training but offers lower prices versus a company that has all the training and gets the business is not a good financial model.

Fullerton: We follow a philosophy that our success is tied to our customers’ successes, so the things we can do to make our customers more successful will lead them to buy and use more solder materials in the long run. You’re right that there are certain situations where a low-cost competitor can undercut us, but that's not really where we play. We play in the value selling market and make sure that the total package that Alpha offers to our customers meets and exceeds their needs and expectations.

As far as the education levels and how to improve that at the university level, there are two things that I see as beneficial. One is something I took advantage of as an undergraduate—I went to a school that offered co-op. There are a number of co-op universities around the country, and I'm going to make a shameless plug for Kettering University in Michigan, which is where I earned my degree back when it was still called GMI Engineering & Management Institute. At Kettering University, completing a series of co-op experiences is a requirement. All students leave the school with a bachelor’s degree and two to three years of hands-on experience in the field that they work in as a requirement to graduate.

Drexel University in Pennsylvania is another good example where co-ops are an integral part of the requirements for their degree program. Other schools have optional programs that they offer their students that some take advantage of, so I sought out and chose a co-op school when I looked at my undergraduate education. I wanted to get both book learning and the hands-on part of the overall package.

Ford Electronics near Philadelphia where I grew up hired me when I was a student. I started as an 18-year-old that knew very little about engineering but learned as I went in that factory about how electronics were being manufactured, different processes, how a factory works, and who's responsible for what. When I graduated, I had practical real-world experience to accompany the piece of paper that said I had a degree in manufacturing engineering. This is a big piece of advice that I always encourage young people to look at when they are considering education opportunities—find ones that package hands-on learning along with classroom education.

The other side is schools like Rochester Institute Technology or Auburn University that have manufacturing labs and programs built around electronics and SMT-type manufacturing, but there are very few of those. There's a lot of investment and equipment and know-how that they need put into that. Manufacturing is not exactly a glamorous industry that is easy to recruit young people into as far as a degree program goes. There is a limitation on how many people are willing to put out that expenditure into building this kind of program and take a risk on a relatively limited field as far as they see.

Holden: I graduated with a lot of my friends because they worked for 14 months between their junior and senior year, so they graduated one year later, but they had over a year of hands-on experience.

Fullerton: There is no value you can put on hands-on experience, especially at that age when you're just learning and forming your understanding of the engineering field. Having hands-on experience where you’re around people that have been doing it for 10–30 years and seeing how they do things is priceless. Plus, you can make the mistakes that don't hurt anybody when you’re young, so you can learn from those mistakes and not repeat them later when it really matters—when you’re in charge of things.

SMTA Europe Solder Finish Webinar Addresses Defects Causes and Cures

12/14/2020 | Pete Starkey, I-Connect007
“What is your most common PCB problem?” A survey conducted by Bob Willis had revealed finish solderability to be the predominant contender, and it was clear that the choice of solderable finish applied to surface mount boards could have a significant effect on the assembly yield and cost of the final circuit. SMTA Europe organised an informative and enlightening webinar this month entitled “Guide to PCB Solder Finishes—Process Defects Causes and Cures,” with soldering specialist Bob Willis as presenter.

Reducing Flux Splatter in Sensors and Camera Modules

10/30/2020 | Jasbir Bath, Shantanu Joshi, and Noriyoshi Uchida, Koki Solder America And Koki Company Limited
With the increased use of electronics in new technology areas, flux formulations are being developed to address the new and existing requirements. For sensors and camera modules used for Advanced Driver Assistance System (ADAS) and internet of things (IoT) applications, there is a demand for no-clean flux formulations in lead-free solder paste, which can reduce flux splattering during reflow.
