Thermals: Thermattach® – T410 and T411
Chomerics' patented THERMATTACH T410 and T411 double sided adhesive tapes provide an effective thermal interface and heat sink attachment method for plastic component packages. The tapes are thermally conductive and have exceptioanl bonding properties. They can also be used to adhere components to verticle heat sinks or to metal chassis walls in place of clips, screws or other mechanical fasteners, without the need for additional thermal compounds.
Thermattach T410
Tape consists of a high bond strength, pressure sensitive acrylic adhesive loaded with aluminum oxide and coated onto a .002 in aluminum foil carrier. The other side of the foil carrier has a silicone pressure sensitive adhesive which provides excellent ahdesion to silicone-contaminated plastics and other low energy surfaces.
Thermattach T411
Tape consists of high bond strength pressure-sensitive adhesive with an expanded aluminum mesh carrier layer. The mesh carrier allows the tape to conform to curved surfaces of plastics molded IC packag, providing a high adhesive strength attachment for heat sinks. The high performance silicone-contaminated plastics and other low enery surfaces.
Performance Characteristics
All THERMATTACH tapes offer excellent thermal, mechanical, enviromental and chemical properties. Vibration testing at 10 G shows no adverse effects. Unlike traditional acrylic pressure-sensitive tapes, after extended temperature/humidity aging and harsh conditions, THERMATTACH tapes meet or exceed initial properties for shear strength and thermal conductivity. With the additional benifit of being able to be removed after application for rework or repairs, THERMATTACH tapes offer many advantages over traditional solutions. It's pliability also reduces concerns over CTE mismatch and cracking or splitting.
