Creative Materials Inc. 129-50LS die-attach adhesive

Creative Materials Inc. has introduced the 129-50LS, a high-temperature, electrically conductive die-attach adhesive. This product is designed for application by syringe dispensing and may also be used with stencil printing, dipping and pin transfer. The high continuous operational temperature of 350°C enables this product to be used in a variety of performance parts which are used in extreme environments. Based on a proprietary modified polyimide, the die-attach adhesive can also be processed at lower temperatures.

The single-component adhesive is NMP-free and complies with semiconductor and die-attach requirements where high Tg, high-temperature performance and low damping are required. The high purity and low extractable ionics allow for long operating life without the need for encapsulation. The high strength and bonding of the adhesive is designed for high performance under thermal shock and mechanical vibratory conditions.

High-performance applications for the adhesive include, but are not limited to, die-attach component mounting in microelectronic and semiconductor packaging, quartz oscillator attachment, hermetic packaging and aerospace applications. The adhesive features a longer working time and lower volatility compared to earlier products. The product has been formulated to be used in production environments where high throughput automated dispense equipment is required.
