WS890

WS890 is an excellent all-around water soluble, lead-free solder paste. It has superior reflow characteristics giving excellent wetting, very low solder balling, and very low graping. WS890 has been formulated for environmental stability giving long stencil life and excellent print characteristics.

Flux type: Water Soluble
Alloys: Lead Free
Classification: ORH1
Halogen: Yes

WS889

WS889 water soluble lead free solder paste is formulated to provide minimal graping and excellent wetting qualities. WS889 displays previously unseen levels of repeatability and consistency even in a wide range of temperatures (65-85 F) and relative humidity (25-65 % RH). Residues are amber in color and can be cleaned using warm water.

Flux Type: Water Soluble
Alloys: Lead-Free
Classification: ORH1
Halogen: Yes
