Alpha's Pujari to Present on Interconnection for Floating PV Applications at Intersolar India


Reading time ( words)

Alpha Assembly Solutions is participating in the upcoming Intersolar India taking place December 1113, 2018, in Bangalore, India.

Narahari Pujari, R&D manager for Alpha Assembly Solutions, part of the MacDermid Performance Solutions group of businesses, will present a technical paper on a review of interconnection technology for floating PV applications that critically assesses various cell designs, material and techniques to join cells for floating PV assemblies.

"It is reported that 40.7% of cSi PV (photovoltaic) modules fail at interconnection in a module’s lifespan. This risk is even higher in floating PV applications. This is due to high moisture content and corrosion resulting from adverse environmental conditions as well as instability in times of inclement weather, hazardous condensation in the interior, etc.," said Pujari. "Additionally, joints that are exposed to fatigue loading and vibrations have shown metal segregation, grain boundary coarsening/cracking, increased series resistance and heating issues. The industry is still evaluating interconnection options in new cell designs. All these make the review of interconnection technologies employed in floating PV imperative."

Pujari's paper will demonstrate the role of non-corrosive flux and EVA compatibility studies. In addition, use of lead-free soldering and solder paste technologies to support the current design trend of new cell architectures will be presented. Both options are cost efficient and could improve the module performance and consequently extend the mean-time-to-failure (MTTF).

Conformal Coatings

08/01/2019 | Nolan Johnson, I-Connect007
While conformal coatings may have been something of an afterthought at the front of the design process, that can no longer be the case. Conformal coatings are now a critical part of any board assembly that might be subjected to challenging conditions. But coatings can also contribute to increased mean time between failure in any conditions, even environmentally controlled environments.

How Do I Get Smart With IPC CFX? (Part 1)

07/30/2019 | Michael Ford, Aegis Software Corp.
Today's assembly factories are seeing the biggest challenge to face the industry in a generation, called by many the next industrial revolution. However, in essence, the challenge is a simple extrapolation of trends that have been occurring and increasing in assembly manufacturing for decades. In Part 1 of this two-part article, Michael Ford writes about the history behind the drive for automation in the SMT assembly industry and where CFX fits in.

Clean vs. No-clean Solder Process

07/03/2019 | Russell Poppe, JJS Manufacturing
Although IPC suggests clear guidelines, agreeing on the cleanliness (or otherwise) of a PCB assembly can often be a subjective and even contentious subject within the electronics manufacturing industry. If you’ve chosen to outsource your assemblies, how do you decide what to specify to your EMS partner? Find out here.
