MacDermid Alpha Micromax 5707 High-Reliability Crossover Dielectric for Single-Layer Circuits
Type: Crossover Dielectric
Application: Single-Layer Circuits
Viscosity: 150–200 Pa.s
Shelf Life: 6 months
Micromax 5707 is a screen printable dielectric for use in single-layer circuits as a crossover between conductor lines. It is compatible with most silver/palladium and gold conductors and is positioned for high reliability. Prints up to 25 cm/s with a double wet squeegee pass to minimize pinholes.
Micromax 5707 from MacDermid Alpha is a screen printable crossover dielectric for use in single-layer circuits, where it serves as an insulator between conductor lines. It is compatible with most silver/palladium and gold conductors, and the TDS lists high reliability as a product benefit. The paste uses Micromax 8672 as the recommended solvent or thinner. It prints at speeds up to 25 cm/s, which supports higher throughput in thick film production.
The paste has a viscosity range of 150–200 Pa.s. Reported properties are based on 96% alumina substrates. Print individual dielectric layers with a 200 or 325 mesh stainless steel screen. The combined fired dielectric thickness should be at least 40 μm; three separate printings may be necessary with 325 mesh screens, while two fired layers achieve 40–45 μm using a 200 mesh screen. Recommended film thickness is 45–50 μm, with theoretical coverage of 60–70 cm²/g. To minimize pinholes, use a double wet squeegee pass. 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 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
Which conductors are compatible with 5707?
The TDS lists compatibility with most silver/palladium and gold conductors. This covers common thick film conductor systems used in single-layer circuit crossovers.
How thick should the fired dielectric be for 5707?
The combined fired dielectric thickness should be at least 40 μm. Using 200 mesh screens, two fired layers achieve 40–45 μm. Using 325 mesh screens, three separate printings may be necessary.
How fast can 5707 be printed?
It will print up to 25 cm/s. This is faster than some crossover dielectrics and supports higher throughput without needing extra print passes.
How should 5707 be fired?
Each dielectric print should be fired separately in a belt furnace. Use a 60-minute cycle with a peak temperature of 850°C for 10 minutes.
How does 5707 minimize pinholes?
The TDS recommends a double wet squeegee pass to minimize pinholes. This helps ensure consistent dielectric coverage over the conductor lines being crossed.
What thinner should be used with 5707?
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 5707 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.
