Engineered Conductive Materials LLC (ECM), a supplier of conductive interconnect materials for photovoltaic applications, has released a new low-temperature curing conductive adhesive (DB-1541-LTC) for use in organic light-emitting diodes (OLED) and organic photovoltaics (OPV).
This material formulation has been optimized for excellent conductivity and stability on various substrates when cured at 100 degrees C or higher, according to the company. The DB-1541-LTC can be cured as low as 100 degrees C and has a dispensing work life greater than 48 hours (measured as a 25% increase in viscosity) while maintaining optimized rheology for dispensing and excellent damp heat resistance and conductivity stability on tin, tin-silver and silver-plated ribbons.
The DB-1541-LTC features a rubber-like flexibility that is ideal for flexible applications with high peel strength to withstand the stresses induced in reel-to-reel manufacturing processes, ECM adds. This material also can be fast cured at elevated temperatures (one minute at 180 degrees C).
