Alpha to Present on Lead-Free Soldering to the cSi Cell Stringing Process at Intersolar India


Reading time ( words)

Alpha Assembly Solutions is participating in the upcoming Intersolar India taking place December 5-7 in Mumbai, India, where global experts focus on photovoltaics, PV production technologies, energy storage systems and solar thermal technologies.

Narahari Pujari, R&D Manager for Alpha Assembly Solutions, part of the MacDermid Performance Solutions group of businesses, will present a technical paper on Lead-Free Soldering to the cSi Cell Stringing Process that focuses on PV market, current trends in the development of lead-free solutions and the impact on manufacturing costs by transitioning away from lead-based solder alloys, which are currently in use predominantly due to their sufficiently low melting points and ability to make reliable solder joints.

"Lead-containing alloys are not only toxic, but can result in hazardous waste classification for PV modules at the end of shelf-life, thus increasing costs overall when safe disposal efforts are included," said Pujari. "In order for the market to embrace the adaptation of lead-free alloys, we must first discuss the market drivers and understand the technological and manufacturing challenges involved with such a migration."

Various available technologies are critically assessed in Pujari's technical presentation which finds that although there is currently no data on long-term reliability of PV modules using lead-free alloys, there is sufficient evidence that supports its likelihood.  Additionally, lead-free solders for PV ribbon are proving to be cost and energy-efficient.

Improving Solder Paste Printing

12/12/2017 | Stephen Las Marias, I-Connect007
Of the three elements involved in the solder paste printing process—stencil, solder paste, and printer—the stencil is considered one of the major factors affecting the transfer efficiency, accuracy, and consistency, of solder pastes into the pads, especially with the continuing trend towards miniaturization.

Equipment Matters in Solder Paste Printing

12/06/2017 | Stephen Las Marias, I-Connect007
The solder paste printing process has always been considered a major contributor to yield loss. According to many studies, solder paste printing accounts for up to 70% of all PCB assembly defects. For the December issue of SMT Magazine, we interviewed experts in the solder paste printing process to learn more about the key issues leading to this huge percentage of defects, and the technology developments that are addressing these challenges and improving yields in the process.

What Matters Most is Communication

12/04/2017 | Stephen Las Marias, I-Connect007
While there may be new techniques and strategies, technologies, equipment, tools, and materials to employ and utilize, there is always one thing that will ensure the manufacturing/ assembly success of your product: communication. Communication between the designer and the assembler will help improve the manufacturability and assembly of the final product—even before the board design gets fabricated.
