Conductive Pastes suit display and solar cell applications.

Press Release Summary:

Targeted at display bus bar electrodes, ElectroSperse D-110, D-112, and D-114 are screen-printable pastes that deliver adhesion when fired onto indium tin oxide or fluorine-doped tin oxide-coated glass. Type D-114 achieves sheet resistivity of 1.2-1.8 mW/sq, while D-112 and D-114 achieve 2-3 and 4-5 mW/sq, respectively. Lead-free products are RoHS and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) compliant.

Five Star Technologies Introduces New Line of Conductive Pastes

CLEVELAND, Oct. 4 / -- Five Star Technologies announced today that it has introduced the ElectroSperse line of silver conductor pastes, initially targeting applications in displays and solar cells. Five Star says the ElectroSperse pastes deliver the same uniform particle size and consistent rheology seen in Five Star dispersions, enabling customers to print fine features consistently and economically. Initial screen printing trials have demonstrated that line widths as narrow as 3 mils can be printed consistently with no loss of conductivity or line integrity.

The initial ElectroSperse offerings, D-110, D-112 and D-114, are targeted at display bus bar electrodes. All three products are screen-printable pastes designed to deliver excellent adhesion when fired onto ITO (Indium Tin Oxide) or F-doped TO (Fluorine-doped Tin Oxide)-coated glass. The series is entirely lead-free, responding to the European market requirements for RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) compliance. The three grades differ in metal content, allowing the user to select a conductivity and price range suitable to the application. ElectroSperse D-114 achieves a sheet resistivity of 1.2-1.8 milli-ohm/sq, while D-112 and D-114 are targeted at 2-3 and 4-5 milli-ohms/sq, respectively. Applications include touch screen sensor electrodes, heater circuits and antennae.

Five Star also offers a line of specialty dispersions that deliver enhanced stability and unparalleled performance for precious metal processing, chip packaging, ceramic components and thick film pastes.
