Micromax 5738R is a cofirable Au conductor, part of the Micromax GreenTape 951 low temperature co-fired ceramic system. It is designed to provide reliable connections between recommended Au conductor layers. When used with GreenTape 951 and compatible conductor pastes, it enables co-fire processing, high conductivity, and high circuit density. Phthalate, cadmium, and nickel oxide free.
Micromax 5738R from MacDermid Alpha is a cofirable Au conductor developed as part of the Micromax GreenTape 951 low temperature co-fired ceramic (LTCC) system. It is designed as a via fill composition, providing reliable connections between recommended Au conductor layers within the GreenTape 951 stack. The paste supports co-fire processing, which allows the via fill and the surrounding LTCC layers to be fired together in a single cycle. It delivers high conductivity and supports high circuit density in LTCC designs. The formulation is phthalate, cadmium, and nickel oxide free, with these substances not intentionally added.
The paste has a viscosity range of 5800–7300 Pa.s and uses Micromax 9450 as the recommended solvent or thinner. Recommended processing procedures for Micromax GreenTape 951 are detailed in the 951 low-temperature cofire dielectric tape technical data sheet. For compatible thick film compositions, consult your Micromax representative. A 20–25 μm thick etched or punched metal stencil is recommended, with a squeegee speed as low as 10 mm/s. Allow prints to level over 5–10 minutes at room temperature, then dry for 5 minutes at 120°C; do not over-dry. Firing conditions should follow the Micromax GreenTape 951 technical data sheet. Clean-up uses 1-propoxy-2-propanol. Store sealed at 5–30°C; unopened shelf life is 6 months.

Frequently Asked Questions
What is the role of 5738R in a GreenTape 951 LTCC stack?
5738R is a via fill composition, designed to provide reliable connections between recommended Au conductor layers in the GreenTape 951 LTCC system. It supports co-fire processing, so the via fill fires along with the surrounding LTCC layers.
What stencil and squeegee settings are recommended for 5738R?
The TDS recommends a 20–25 μm thick etched or punched metal stencil, with a squeegee speed as low as 10 mm/s. This combination helps fill vias consistently in the LTCC green tape.
Why does the TDS say “do not over-dry” for 5738R?
The drying schedule is 5 minutes at 120°C after leveling for 5–10 minutes. Over-drying can affect the via fill’s co-fire behavior with GreenTape 951, so the TDS explicitly warns against extending the dry time or temperature beyond the recommendation.
Where can I find firing conditions for 5738R?
The TDS directs users to consult the Micromax GreenTape 951 technical data sheet for firing conditions. Since 5738R is part of that LTCC system, the LTCC tape TDS contains the co-fire profile.
What clean-up solvent is used with 5738R?
1-Propoxy-2-Propanol is listed as the clean-up solvent. Using the specified solvent helps maintain screen and stencil condition between runs.
Is 5738R free of phthalate, cadmium and nickel oxide?
Per the TDS, phthalate, cadmium, and nickel oxide are not intentional ingredients and are not intentionally added. Trace amounts may be present. Customers with strict compliance thresholds should verify against their own requirements.
How should 5738R be stored?
Store tightly sealed at 5–30°C in a clean, stable environment. Unopened shelf life is 6 months from shipment. Some settling may occur, so mix thoroughly before reuse.
