Applications that benefit from film adhesives

Precision Applications with Mechanical Strength: Compared to pastes and liquid adhesives, die cut films can be precisely placed keeping adhesive where it is needed and contamination away from sensitive components.

Thermal Management: With consistent thickness and void free application, films offer inherent thermal advantages compared to traditional paste or thermal tape products. With thermal conductivity up to 7 W/mK, film products maximize thermal transfer for the most demanding heat applications.

RF and Microwave Assembly: Traditionally the realm of solder where air voids routinely require electrical adjustments and rework, the void free application of electrically conductive films are transforming the manufacture of RF and microwave assamblies.

low Temperature Lead Free Assembles: Films, as well and Emerson & Cuming/s electrically conductive adhesives, can be your solution for lead free com
