MacDermid Alpha Micromax 6118H Silver Conductor Blend Member
Type: Silver Conductor Blend Member
Series: Green Tape 6118A/6118H
Solids: 84–86%
Shelf Life: 6 months
Micromax 6118H is a blend member used to adjust the viscosity of Micromax 6118A co-fired silver plateable conductor for Micromax 951 and 9K7 GreenTape systems. It offers high conductivity, electroless Ni/Au plateability, wirebondability with 1 mil Au wire after plating, brazeability with Au80/Sn20 after plating, and is lead free and cadmium free.
Micromax 6118H from MacDermid Alpha is a blend member developed to adjust the viscosity of Micromax 6118A co-fired silver plateable conductor for Micromax 951 and 9K7 GreenTape low temperature co-fired ceramic systems. It is part of the Green Tape 6118A/6118H series, giving formulators a way to fine-tune the viscosity of 6118A when production conditions require it, without switching to a different conductor platform. The composition is lead free and cadmium free, with these substances not intentionally added.
The paste carries 84–86% solids, measured at 750°C, and a viscosity range of 350–500 Pa.s measured with Brookfield RVT, #14 spindle, 10 rpm, 25°C. Micromax 8250 is the recommended solvent or thinner. Print with a 325-mesh stainless steel screen with 1.1 mil wire at 45 degree mesh angle and less than 0.5 mil emulsion. Printing thickness must be controlled at 15–22 μm dried for optimum performance, with recommended film thickness of 15–22 μm. Mix thoroughly before use by slow, gentle hand stirring with a clean burr-free flexible plastic spatula for 1–2 minutes, avoiding air entrapment. Printing should be performed at 20–23°C. Allow prints to level 5–10 minutes at room temperature, then dry at 80–120°C for 5–10 minutes in a well-ventilated oven or conveyor dryer.
Laminate external tape layers printed with Micromax 6118A/H to multiple sheets of GreenTape using the recommended processing parameters in the Micromax GreenTape Design Guideline and the 951 and 9K7 product data sheets. Typical lamination conditions are 3000 psi at 70°C for 10 minutes. Consult the Micromax GreenTape 951 and 9K7 technical data sheets for firing recommendations; these systems require a special 26-hour firing profile. Appropriate plating conditions are required and results may vary. For brazing, a special profile with a peak temperature of 300°C for 5 minutes in nitrogen is recommended. Store sealed at 5–30°C; unopened shelf life is 6 months.

Frequently Asked Questions
When should I use 6118H instead of 6118A alone?
The TDS states that 6118H is a blend member used to adjust the viscosity of 6118A when needed. If 6118A requires a higher or different viscosity for a particular print condition, 6118H can be blended in to shift the viscosity without changing the conductor platform.
What viscosity range does 6118H have?
6118H has a viscosity range of 350–500 Pa.s, measured with Brookfield RVT, #14 spindle, 10 rpm at 25°C. This is higher than the typical range for 6118A, which supports its use as a viscosity modifier.
What film thickness and print thickness does 6118H target?
Recommended film thickness is 15–22 μm. Printing thickness must be controlled at 15–22 μm dried for optimum performance, using a 325-mesh stainless steel screen with 1.1 mil wire at 45 degree mesh angle and less than 0.5 mil emulsion.
What firing profile does 6118H require?
The TDS directs users to consult the Micromax GreenTape 951 and 9K7 technical data sheets for firing recommendations. These systems require a special 26-hour firing profile. Contact your Micromax technical representative for details.
Can 6118H be plated and brazed like 6118A?
The TDS lists the same benefits for 6118A/6118H as a series, including electroless Ni/Au plateability, wirebondability with 1 mil Au wire after plating, and brazeability with Au80/Sn20 after plating. Appropriate plating conditions are required and results may vary.
What lamination and brazing conditions apply to 6118H?
Typical lamination conditions are 3000 psi at 70°C for 10 minutes. For brazing, a special profile with a peak temperature of 300°C for 5 minutes in nitrogen is recommended.
How should 6118H 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.
