MacDermid Alpha Micromax 4899R is a solderable silver termination paste designed for multilayer ceramic capacitors (MLC). Featuring Pb/Cd/phthalate-free formulation, 850°C 40-minute firing, and dip application with good solderability and adhesion over a wide range of capacitor bodies per TDS specifications.
Micromax 4899R is a solderable silver termination paste designed for lead attachment to multilayer ceramic capacitors. This cadmium-free and lead-free termination offers good solderability and high adhesion over a wide range of capacitor bodies. The paste is ideal for applications where platable terminations are not desired but where soldering conditions are required. It is optimized for carrier plate-type dipping applications with a viscosity of 45-75 Pa.s per TDS specifications.
With a solid content of 74.5-76.5%, Micromax 4899R is applied by dipping and dried using a belt dryer at 160-180°C for 15 minutes. The paste fires at 850°C peak with a 40-minute cycle and 10-minute peak hold. The composition is compatible with ceramic capacitor bodies and delivers reliable solderability and adhesion. Available in standard packaging with 6-month shelf life per TDS specifications.
