Engineered Conductive Materials Debuts 530-121 Low-Cost Conductive Adhesive
Jul 06, 2012
Engineered Conductive Materials introduces the new 530-121 low-cost conductive adhesive designed for ribbon stringing in thin-film solar modules. The price of this material formulation is 60 percent of the cost of a pure silver-filled material and has been optimized for excellent conductivity and stability on various substrates when cured at
The 530-121 has a dispensing work life greater than 48 hours (measured as a 25 percent increase in viscosity), while maintaining optimized rheology for dispensing and excellent damp heat resistance. Also, the material has conductivity stability on molybdenum and tin, tin-silver and silver-plated ribbons. The 530-121 features a rubber-like flexibility that is ideal for flexible photovoltaic applications with high peel strength to withstand the stresses induced in reel-to-reel manufacturing processes. This material also can be fast cured at elevated temperatures (2 minutes @ 1800C).
530-121 is the latest addition to Engineered Conductive Materials' full line of conductive stringer attach adhesives, conductive adhesives for back contact crystalline silicon, thin-film and via fill applications, as well as conductive grid inks for photovoltaic applications.
