Alpha's Narahari Pujari to Present at 2017 Metallization and Interconnection Workshop


Reading time ( words)

Alpha Assembly Solutions is participating in the upcoming Metallization and Interconnection Workshop taking place October 23–24 in Kostanz, Germany, where global experts will discuss status, trends and new product roadmaps for crystalline silicon (cSi) solar cells.

Narahari Pujari, R&D Manager for Alpha Assembly Solutions, part of the MacDermid Performance Solutions group of businesses, will present a technical paper titled "Non-Eutectic Low Melting Temperature Alloys for Standard cSi Interconnection", which focuses on the expected changes in worldwide regulations that will require lead-bearing solders be replaced with less toxic alternatives.

"Lead-based solders have been used predominantly in PV applications due to their sufficiently low melting points and ability to make good, reliable solder joints between busbars and PV ribbon," says Pujari. "The critical components to consider for transitioning to lead-free solders are cost-efficiency and repeatable high performance, which are necessary to mirror the properties of lead-based solders currently in use."

Pujari's presentation will report on new non-eutectic alloys for tinning PV ribbon and cSi interconnection that were tested and benchmarked against standard tin-lead alloys for thermal and mechanical properties as well as functional performance.

Solder Printing Process Inputs Impacting Distribution of Paste Volume

12/14/2017 | Marco Lajoie and Alain Breton, C-MAC Microelectronics
The volume of solder deposition, like any process, has variations that may be characterized by a statistical distribution curve, whether normal or non-normal. As complexity, density, cost and reliability requirements increase, there may be value in narrowing the distribution curve. It is common sense that less variation serves the interest of quality of the more complex and dense circuit boards.

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.
