User manual 3M FLEXIBLE CIRCUIT DAMPING

[. . . ] Application Profile Market: Hard Disk Drive Assembly Application Description: Flexible Circuit Damping 3MTM Ultra-pure Viscoelastic Damping Polymer Constraining Layer Flex Application Method Applied as die cut parts. PRODUCT 3MTM Ultra-pure Viscoelastic Damping Polymer 242R, JPV-116SF Key Application Requirements Reduce vibration during operation of the Hard Disk Drive (HDD). Benefits/Advantages To Customer Reduces vibration: 3MTM Ultra-pure Viscoelastic Damping Polymer absorbs vibrations of the flexible circuit. [. . . ] Surface Type - The 3M ultra-pure viscoelastic damping polymer will form good bonds when properly applied to many high surface energy materials. Materials with a surface energy below 100 dynes/cm2 should be tested to determine if a suitable development of an adequate bond for a given end use application will occur. Application - The 3M ultra-pure viscoelastic damping polymer is tacky at room temperature (21ºC). The 3M polymer requires only rolling or squeegeeing methods to apply pressure to the 3M polymer to make an adequate bond to a contamination free surface. A good method is to first attach one edge of the damper with it's liner removed to the substrate, then gradually lower the damper or damping polymer onto the surface at an angle of (30-90º) while continually applying uniform pressure to the damping polymer of 10-15 psi (6. 9-10. 3 pascals). Every effort should be made to avoid air entrapment while placing the damping polymer onto the flexible circuit substrate.
