- Description
- Technical specification
For continuous high resistance to delamination and popcorning, choose LOCTITE® ABLESTIK QMI529HT-2A1. This high strength, hybrid technology, electrically conductive die attach adhesive is hydrophobic, and ideal for high accuracy applications with consistent bondline thickness for superior functionality.
This product and its use may be covered by patent 5,716,034 and by one or more pending patent applications.

FAQ
Do not try to reduce the thawing time by rubbing the syringes between the hands or by use of any type of heating device. When ready to use the ECA, transfer the needed syringes from the syringe box in the freezer to a designated thaw area using thermal gloves. While frozen, only handle the syringe by the flanges located at the top end of the syringe. This will minimize thermal shock and reduce the likelihood of FTVs from forming. During thaw, the syringes should be stored in the vertical position. Thaw times vary depending on syringe size but are typically >1 hour.
A hybrid system "combines the best of two worlds". In this case we combine a BMI (Bismaleimide Resin) that provides low moisture absorption and low viscosity for ease of dispensing for die attach applications with an Acrylic resin to provide fast curing in high throughput applications.
