Parker Chomerics THERMATTACH® T404 Thermally Conductive Attachment Tape
Categories: Polymer; Tape

Material Notes: Description: THERMATTACH® double-sided thermal interface tapes provide exceptional bonding properties between electronic components and heat sinks, eliminating and need for mechanical fasteners. THERMATTACH® tapes are proven to offer excellent reliability when exposed to thermal, mechanical, and environmental conditioning.

Features/Benefits: Offered in various forms to provide thermal, dielectric, and flame retardant properties; Offered in custom die-cut configurations to suit a variety of applications; Eliminate the need for mechanical attachment (i.e. screws, clips, rivets, fasteners); Proven reliability under various mechanical, thermal, and environmental stresses; Embossed version available; Meets RoHS specifications; No curing required, unlike epoxy or acrylic performs or liquid systems and Easily reworkable

Typical Applications: Mount heat sinks to components dissipating < -25 W; Attach heat sinks to PC (esp. graphics) processors; Heat sink attachment to motor control processors and Telecommunication infrastructure components.

Product Attributes: Excellent dielectric strength due to polyimide carrier; Good thermal performance and Without halogenated flame retardant
