Lid & Optical Seal Solutions

SNAP-LID® Adhesive Preform Pre-application

Patent pending low cost pre-application of adhesive preforms on plastic, ceramic, metal lids. Instant tacking-bonding for in-line processes for both thermoplastic and epoxy-based adhesives. AIT provides both pre-applications on your parts or provides complete solution with lids.

Lid Sealing Laboratory

COOL-LID® Lid Attach to Combine with Thermal Management

A solution incorporating heat-spreading interface from a flip chip device and module to the lid cover is accomplished with an AI Technology adhesive that is pre-applied and provides for a rapid bonding lid attach.This new technology combined the now world-renown COOL-PAD™ interface solution for devices generating more than 100 watts within a square inch area along with the snap-curing adhesive preform combine to provide a winning solution for the majority of lid attachment applications. COOL-LID® is a special cost effective patent-pending process where pre-application of thermal interface material and lid-seal adhesive are used. Lids may be constructed of copper, aluminum, and ceramics. If thermal performance is not critical, even plastic caps can be used. The B-staged lid seal adhesive and interface pad are dry to the touch and are ambient storable for 12 months. Both the adhesive and interface material will tack onto a substrate and form an intimate thermal contact at 150°C in a matter of seconds with nominal pressure of 10 psi. Full cure is achieved without pressure at 150°C in less than 5 minutes.

Lid Attach Dispensible Insulating and Conductive Adhesive

AIT engineered and designed several innovative lid-sealing solutions for optical, thermal, EMI and commercial component and module packaging with outstanding cost effectiveness. It is ideal for the MEMS and wafer level lid sealing applications. The following are some examples:

AI Technology produces one of the unique dispensible lid-seal adhesives that can be cured at relatively low temperature of 100-200°C and yet capable of withstanding operation temperature of beyond 300°C continuously. While not as perfect hermetic seals as metal and glass seal, the cured lid seals passed gross and fine leak tests for almost all commercial applications. It is ideal for CMOS and other optical imaging devices.

CMOS Devices

1. MC7883 Insulating Paste Adhesive:

  • 100% solid, insulating lid-seal that cured inline at temperature of 175-200°C in a few seconds.
  • Low coefficient of expansion (CTE) of less than 20 ppm/°C with low moisture absorption of less than 0.5% at saturation for long-term device reliability under thermal and environmental stresses.
  • High glass transition of 240°C and long-term molecular stability above 300°C to ensure both standard commercial and military applications of 85C and 150°C continuously. It also enables the special ultra high temperature operational as sensors and electronic devices in oil wells and other specialty environments.

2. MC8880 paste adhesive:

  • 100% solid, electrically conductive lid-seal that cured inline at temperature of 175-200°C in a few seconds.
  • Low coefficient of expansion (CTE) of less than 25 ppm/°C with low moisture absorption of less than 0.5% at saturation for long-term device reliability under thermal and environmental stresses.
  • High glass transition of 240°C and long-term molecular stability above 300°C to ensure both standard commercial and military applications of 85°C and 150°C continuously.
