Solder paste ISO-Cream "Clear"
The ISO-Cream "Clear" from Felder is a highly developed SMD solder paste, distinguished by its excellent wetting on all types of printed circuit board surfaces, especially on NiAu and NiPd. This solder paste is specifically designed for use in both normal and protective gas atmospheres as well as in vapor phase, and is characterized by its halogen-free (<0.01%) and rosin-free nature. The paste leaves clear, inconspicuous residues and shows a low tendency for void formation.
The ISO-Cream "Clear" offers optimal printing properties and excellent contour stability. With a long processing time of at least 48 hours and a high squeegee life of up to 8 hours, this solder paste enables efficient processing throughout the entire production time. The solder paste is formulated with a particle size of 25-45 µm (KG 3) and a metal content of 88.5%, leading to precise and reliable solder joints.
The lead-free alloy Sn95.5Ag4Cu0.5 ensures a eutectic melting point of 217 °C, making the ISO-Cream "Clear" particularly suitable for demanding applications. Felder relies on state-of-the-art testing and control procedures to ensure consistently high quality, and offers the option to adjust the paste's viscosity to customer specifications between 300 and 900 Pa s.
