MacDermid Alpha Micromax 5704 Pinhole-Free Multilayer Dielectric for High-Reliability Circuits
Type: Multilayer Dielectric
Application: High-Reliability Circuits
Solids: 73–75%
Shelf Life: 6 months
Micromax 5704 is a screen printable dielectric for multilayer circuits, used as an insulator between conductor layers. It prints up to 15 cm/s squeegee speed and fires to a pinhole-free smooth surface. A 325 mesh screen is recommended for best via resolution, and a double wet squeegee pass helps minimize pinholes.
Micromax 5704 from MacDermid Alpha is a screen printable dielectric developed for multilayer circuits, where it serves as the insulator between conductor layers. The paste prints at squeegee speeds up to 15 cm/s (6 in/s) and fires to a pinhole-free smooth surface, which supports reliable interlayer insulation in high-reliability thick film circuits. It uses Micromax 8672 as the recommended solvent or thinner.
The paste carries 73–75% solids and a viscosity range of 150–250 Pa.s. Reported properties are based on 96% alumina substrates. Print individual dielectric layers with a 200 or 325 mesh stainless steel screen; a 325 mesh screen is recommended for best via resolution. To minimize pinholes, use a double wet squeegee pass. The total fired dielectric thickness should be at least 40 μm (1.6 mil); three separate printings may be necessary to reach this with 325 mesh screens. Recommended film thickness is 45–50 μm, with theoretical coverage of 60–70 cm²/g based on 50 μm wet film. Allow the wet print to level 5–10 minutes at room temperature, then dry at 150°C for 10–15 minutes. Each dielectric print should be fired separately in a belt furnace, using a 30 or 60 minute cycle with a peak temperature of 850°C for 10 minutes. Store sealed at 5–30°C; unopened shelf life is 6 months.

Frequently Asked Questions
Why is 5704 described as pinhole-free?
The TDS states that 5704 fires to a pinhole-free smooth surface. Using a double wet squeegee pass and a 325 mesh screen for best via resolution helps achieve this in multilayer circuit builds.
How thick should the fired dielectric be?
Total fired dielectric thickness should be at least 40 μm (1.6 mil). With 325 mesh screens, three separate printings may be necessary to reach this thickness.
How fast can 5704 be printed?
Printing speeds up to 15 cm/s (6 in/s) can be achieved. This supports higher throughput without sacrificing the pinhole-free surface.
How should 5704 be fired?
Each dielectric print should be fired separately in a belt furnace. Use a 30 or 60 minute cycle with a peak temperature of 850°C for 10 minutes.
How can contamination affect 5704 processing?
The TDS notes that yield and performance depend significantly on care during processing, particularly screen printing. Keep the dielectric, screens, and tools free of metal contamination; dust, lint, and particulate matter can also contribute to poor yields.
What thinner should be used with 5704?
Micromax 8672 is the listed solvent or thinner. Using the recommended thinner helps keep viscosity and print behavior consistent with the TDS values.
How should 5704 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.
