MacDermid Alpha Electronics Solutions products

Flux coated Exactalloy preforms offer a significant increase in productivity in processes requiring flux. Rosin based formulas are available in a full range of activity levels (see flux overview and classification chart). With Alpha’s unique glazing process, flux coatings can be fused into a clear, continuous surface, highly resistant to flaking and flux loss during storage and handling. The external flux coating is designed to become active prior to the complete melting of the solder preform. It flows to cover the solder preform during its transformation from solid to liquid, while providing wetting action for the substrates being soldered.
