MacDermid Alpha Micromax 5715G Gold Wire Bondable Conductor for High-Density Hybrids
Type: Gold Wire Bondable Conductor
Application: High-Density Hybrids
Viscosity: 450–600 Pa.s
Shelf Life: 6 months
Micromax 5715G is a cadmium-free, screen printable gold conductor used as a gold wire bondable conductor in high-density hybrids. It offers good automatic gold wire bonding yields with 1-mil and 2-mil wire, excellent wire bond acceptance over a broad thickness range, and a fired conductor with excellent surface smoothness.
Micromax 5715G from MacDermid Alpha is a cadmium-free, screen printable gold conductor developed for high-density hybrid circuits. It is used as a gold wire bondable conductor, providing good automatic gold wire bonding yields with both 1-mil and 2-mil gold wire. Wire bond acceptance is excellent over a broad thickness range, which gives flexibility in designing the conductor layer. The fired conductor exhibits excellent surface smoothness, supporting consistent bonding results.
The paste carries a viscosity range of 450–600 Pa.s and uses Micromax 8672 as the recommended solvent or thinner. Reported properties are based on 96% alumina substrates. A 325 mesh stainless steel screen with 12 μm (0.5 mil) emulsion thickness is recommended, and printing speeds up to 15 cm/s (6 in/s) can be achieved. Allow the wet print to level 10–15 minutes at room temperature, then dry at 150°C for 15 minutes. Fire dried prints in a belt furnace on a 30-minute cycle with a peak temperature of 850°C for 10 minutes. No significant changes in performance characteristics were seen after multiple refiring at 850°C. Bonding was tested on a Palomar 2460-V Automatic Gold Wire Bonder, stage 150°C, ceramic tool, 1.0 mil Au wire, tensile strength 8 g min, elongation 3–5%. Store sealed at 5–30°C; unopened shelf life is 6 months.
