Component & Substrate Attach Paste Adhesives

AIT Substrate and Component Attach Paste Adhesives Designed for Stress-Free Large Area Bonding:

  • Stencil and screen printed epoxy
  • B-stageable epoxy adhesive
  • Cyanaesther based high temperature adhesives
  • Adhesives dispense and rapidly cure for surface mounting of components
  • Controlled thixotropic index for precise positioning of components
  • Rapid heat curing for high volume through-put manufacturing
  • High thermal conductive electrically insulating adhesive
  • Electrically conductive and thermally conductive adhesive

Performance Characteristics:

  • Stress free bonding proven for robust applications
  • Provides for reliable and long-term stability with molecular flexibility
  • Non-silicone and non-contaminating

Substrate and Component Attach Paste Adhesives are Designed for Stress-Free Large Area Bonding with Molecularly Engineered Polymer Structures

AIT has many proven epoxy paste adhesives for thermal management in component and substrate attachment. The ME8456 series of flexible conductive adhesives has been the mainstay of conductive adhesives used for microwave applications in military electronics with 20 years of proven success.

The following tables are representative of products that have been engineered for:

  • Microwave large and small area substrate attach
  • Inline curing SMT adhesive with outstanding pot-life and dispensing properties
  • Patented solder-replacement component attach conductive adhesives
