Directions For Use

Flow under the component is quick at room temperature. Flow rate can be increased by preheating substrate to as high as 90 C. Dispense encapsulant along one edge or two adjacent edges of the component. Multiple dispensing strokes may be required to dispense sufficient material to underfill the entire component. Recommended cure temperature is actual temperature of the encapsulant. For other cure temperatures, consult your Zymet sales representative.

Directions For Rework

In general, the process is straightforward. Remove component using a BGA rework station. Remove solder with a solderwick. Heat the underfill and remove using an orange stick. For more detailed instructions, contact your Zymet sales representative.

Storage And Handling

Store at -5 0 C. Pot life is 14 days at room temperature. Use good industrial hygiene to avoid skin and eye contact. Wash off affected area with soap and water.
