樂泰 3629
樂泰 3629 is designed for the bonding of surface mounted devices to printed circuit boards prior to wave soldering. Particularly suited where low curing temperatures are required with heat sensitive components, and in applications where short curing times are required. 樂泰 3629 has been used successfully in lead free processes with water and alcohol based fluxes under conditions outlined in the Environmental Resistance section.

TYPICAL CURING PERFORMANCE
Recommended conditions for curing are exposure to heat above 100°C (typically 110 to 140 seconds @ 120 °C or 3 to 5 minutes @ 110 °C). Higher cure temperatures such as 150 °C can be used to shorten cure times. Rate of cure and final strength will depend on the residence time at the cure temperature.
Cure Speed vs. Time, Temperature
The following graph shows the rate of torque strength developed with time at different temperatures. These times are defined from the moment the adhesive reaches cure temperature. In practice, total oven time may be longer to allow for heat up period. Strength is measured on 1206 capacitors @ 22 °C, tested according to IPC SM817, TM-650 Method 2.4.42.
