樂泰 3621
樂泰 3621 is designed for the bonding of surface mounted devices to printed circuit boards prior to wave soldering. Particularly suited for applications where very high dispense speeds, high dot profile, high wet strength and good electrical characteristics are required. Particularly suited where dispense speeds greater than 35,000 dots/h are required. 樂泰 3621 has been used successfully in lead free processes with water and alcohol based fluxes under conditions outlined in the Environmental Resistance section.

VISCOSITY VS. TEMPERATURE
The following graph shows a typical temperature-viscosity curve as measured using a Haake rotoviscometer PK100, M10/PK1 2° Cone system at a shear rate of 2 s -1 which is representative of the shear rate in the dispense nozzle. Increased cabin or nozzle temperature in the 30°C to 35°C range may aid dispense performance at higher dispense speeds.
