Application Instructions

Application tools include brushes, dispensing machines, or cotton swabs.

Brushes are recommended for thin encapsulation

Dispensing machines are suitable for thick encapsulation

Preheat the PCB on a hot plate at 60°C–150°C, then dispense LT-2038-L onto the designated area.
The dispensing amount should be adjusted according to the size of the IC (CMOS).

The adhesive will gel quickly after dispensing.
Finally, place the treated assemblies in an oven and cure at 130°C–150°C for 60–90 minutes until fully cured.
Curing time may vary depending on product size and quantity.
