Characteristics
Designed for maximum robustness in reflow profiling and printing. Contains the widest possible reflow processing window. Capable of printing downtimes of up to 90 minutes with an effective first print down to 20 mils. Maintains its activity and printing characteristics for up 8 hours without any shear thinning. Compatible with enclosed print head systems.
Full residue, standard no-clean paste for all reflow applications. R244 has been an industry standard formula that combines many good properties into a user friendly product
Designed as an all-purpose water-soluble paste, Hydro Mark 531 provides consistent hours of stable stencil life, tack time, and printing characteristics. Offers improved anti-slump characteristics along with excellent solderability to a wide range of surface and component lead metallizations, solving problems caused by slumping, bridging, and wetting.
A general application water-soluble paste that demonstrates exceptional characteristics in all weather environments and reduced voiding in BGA attach operations. R562 maintains its print characteristics, tack, and activity even after prolonged exposure to environmental extremes.
Designed to reduce voiding in BGA solder connections and print over a range of environmental conditions. R560 features extremely stable stencil and tack life, while exhibiting excellent wetting to a variety of metalizations. Compatible with enclosed print head systems.
