PV Ribbon Manufacturing

Alpha understands the complete process and produces a host of high-performance materials specifically designed to meet the needs of the photovoltaic industry.  Alpha alloys are manufactured using our proprietary Vaculoy® process which minimizes drossing of the alloy during the coating process.  Several alloys are engineered to minimize copper erosion.  In order to meet the need for lead-free solder alternatives, Alpha offers several quality products, including EcoSol – the industry’s first Pb-free alloy to have similar performance attributes as SnPb alloys and at a similar cost.
