FAQ
Q1: What is the 3290 adhesive mainly used for?
3290 is a UV moisture dual-cure adhesive designed for chip fixing (die attach) and electronic component reinforcement, providing reliable, durable bonding in precision assemblies.
Q2: How does the dual-cure system work?
It cures fast under UV light at 800 mJ/cm², and shadow areas not exposed to light cure gradually through moisture for complete curing.
Q3: How does fluorescence detection help?
The adhesive features fluorescence detection, making applied areas easy to inspect under UV light for accurate coverage and quality control.
Q4: How strong is the adhesion?
3290 provides excellent adhesion and good toughness, ensuring reliable chip fixing and component reinforcement performance.
Q5: Is the odor low during application?
Yes. 3290 features a low odor formulation, providing a more comfortable working environment for operators.
Q6: What are the storage conditions?
Store at 8-28°C in the original sealed container. Shelf life is 12 months. Available in 50g and 300g packaging.
