RP Au 041008-22% H
Gold Resinate Paste / DPIS*
* Development Product Information Sheet
Description
RP AU 041008-22% H is a thin film conductor paste for use
on alumina and glazed alumina. RP Au 041008-22% contains
gold and a small amount of non-precious metals in form of
soluble organo metallic compounds.
After firing a conducting gold film is obtained. Due to
simultaneous sintering of non-precious metal oxides RP Au
041008-22% offers a high adhesion on above mentioned
substrates.
To reach higher film thicknesses it is necessary to print several
layers on top of each other. Each applied layer has to be fired
separately.
Key Benefits
• Suitable for use as thermal print heads, pressure
sensors, etched conductor structures and fuses
• Free of lead, cadmium and nickel
• Free of phthalate
• RoHS

Processing
1. Spatulate well prior to processing:
When stored in a refrigerator allow paste to come to room
temperature prior to opening, to avoid condensation.
2. Print through a 300 – 350 mesh stainless steel screen with
an emulsion thickness of 15 – 20 µm.
3. Let the print settle at room temperature for 10 minutes.
4. Dry at 90 °C for 15 minutes.
Do not exceed peak of 130 °C.
5. Fire at 850 °C (peak) for 7 – 10 minutes and with a total
firing cycle time of 40 – 60 minutes.

1 Typical properties based on laboratory test methods. For optimum
results all materials should be fired in a profiled furnace supplied
with dried, hydrocarbon and other contaminant free air (PP-1).
2 Measured on alumina 96% after printing with a 325 mesh steel
screen; thickness of screen and emulsion combined was c. 15 µm,
and the resultant printed track was 500 µm wide.
3 RoHS compliant according to the latest ** Directives (European
Union) of Restriction of Hazardous Substances (“RoHS”) and its
subsequent amendments (including the exceptions related to Pb)
4 REACH compliant according to the latest ** Annex XIV to Regulation
(EC) of the European Parliament and of the council on the
Registration, Evaluation, Authorisation and Restriction of Chemicals
(“REACH”) by European Chemicals Agency and its subsequent
amendments: the material does not contain any substance listed in
Annex XIV.
