Alpha to Showcase New Tabbing and Stringing Flux at SNEC PV Power Expo in Shanghai

Somerset, NJ – April 3, 2017

Alpha Assembly Solutions, the world leader in the development of joining materials for PV module assembly, will introduce their new ALPHA® PV-38i Liquid Flux at the SNEC PV Power Expo taking place April 19th – 21st in Shanghai, China.

ALPHA® PV-38i Liquid Flux is the latest generation tabbing and stringing flux with the lowest level of solids in the industry and is designed for high throughput, automated tabbing and stringing equipment, using both dip and spray-on cell flux applications.

Photovoltaic energy has become cheaper and more available in the market, while achieving growth in recent years. As this growth curve persists, PV module manufacturers increasingly require higher throughput of their production lines with higher degrees of automation and flexibility. As the number of busbars in the photovoltaic cells increases from four to five and six busbar models, the bussing and interconnect soldering process becomes a bottleneck in the production line.

“Most liquid spray fluxes currently used have been taken directly from the electronics assembly industry and are not specifically designed or suitable for these newer advanced busbar models”, said Michael Previti, Global Product Manager for Liquid Flux and Chemicals. He continues, “These liquid flux materials have higher solids in their formulas that pollute the current generation of high-volume automated tabbing and stringing machines, as well as clog the spray nozzles, requiring the production line to shut down for periodic cleaning. Therefore, Alpha’s development focused specifically on designing a liquid spray flux to meet the current high throughput challenges of PV module assemblers of four, five and six busbar models. The resulting ALPHA® PV-38i liquid spray flux contains the lowest level of solids commercially available in the industry, causing less pollution inside the machine and reduced instances of clogged spray nozzles.”

In addition, Michael Previti will be presenting a paper entitled “Benefits of Reduced Solids Tabbing & Stringing Fluxes for PV Module Manufacturing” from 09:30am - 09:45am on April 20 in the Pudong Ballroom 5-7 at the Kerry Hotel. This paper will discuss the benefits of low solids fluxes developed specifically to meet the soldering and production speed challenges of the latest PV module assembly processes.
