MacDermid Alpha Micromax 1718H is a screen-printable resistor composition from the 17G-Series, specifically formulated and tested for use on gold (Au) conductor terminations. It delivers 90-110Ω/sq sheet resistance with TCR within ±100 ppm/°C and excellent post-laser trim stability, optimized for 850°C air firing.
Part of the Micromax 17G-Series, MacDermid Alpha Micromax 1718H is a gold-compatible thick-film resistor paste engineered for hybrid circuit applications requiring gold conductor terminations. This composition is specifically qualified and tested on gold conductors, delivering consistent electrical performance with TCR values within ±100 ppm/°C. The material exhibits excellent post-laser trim stability in both encapsulated and unencapsulated conditions, making it a dependable choice for precision resistor networks on gold-terminated substrates.
The paste offers a sheet resistivity of 90-110Ω/sq and is optimized for 200-mesh stainless steel screens with 12-18 μm emulsion thickness, producing a dried film thickness of 22-28 μm. A 60-minute air firing cycle with a 10-minute peak hold at 850°C delivers optimal electrical characteristics. The 17G-Series is fully blendable with adjacent members — there are no blend breaks, and resistivity and TCR values blend smoothly and predictably at all ratios. The material is RoHS compliant and available in 100G and 1000G standard packaging.
