Alpha to Present on Lead-Free Soldering to the cSi Cell Stringing Process at Intersolar India
November 13, 2017 | Alpha Assembly SolutionsEstimated reading time: 2 minutes
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.

Overview of Soldering Systems With Vacuum
12/18/2024 | Dr. Paul Wild, Rehm Thermal Systems GmbHWhen soldering electronic assemblies, the focus of the vacuum application is on the removal of volatile substances from the solder joints and the associated reduction of pore formation. Particularly in the thermal management of power electronics components, pores can cause so-called hotspots with higher temperatures due to their poor heat conduction. These hotspots can lead to overheating of the components on the one hand and to thermally induced destruction of the solder structure on the other.
