Creative Materials 126-37

126-37 is a screen-printable, B-Stageable, anisotropic conductive, one part epoxy adhesive, suitable for application by screen-printing and syringe dispensing. 126-37 is designed to exhibit minimal flow during bonding. This product provides superior electrical conductivity when bonding circuit materials to metal back planes and heat sinks. This product has excellent adhesion to aluminum, ceramic, and a variety of other substrates. Additional applications include, but are not limited to, assembling electrical and electronic components. This system features excellent thermal stability and flexibility in the B-Staged form. 126-37 is an anisotropic conductive version of 125-22.

    B-stage Procedure

    Apply adhesive to substrate or release liner. Next apply heat to advance the curing to the non-tacky stage when cooled to room temperature. A temperature of 100°C to 120°C for 2 to 5 minutes is required, B-Stage time is mass related. User is encouraged to experiment for optimum drying time at a given temperature.

    Bonding Procedure

    To use, apply b-staged adhesive to one part, carefully align parts to be bonded, apply uniform pressure to maintain location. Cure for 15 minutes at 200°C, or 30 minutes at 175°C, or 1 hour at 160°C. For better adhesion of the bstaged film to the first part, it is suggested to warm the part to 40°C. Cure times given are mass related, timing should start after adhesive and substrates reach curing temperature.

    These temperatures and times are presented as a guide only. The end-user is encouraged to experiment to determine optimum curing schedule.

    Handling And Storage

    Material is ready to use as received. Store frozen to maintain consistent flow properties. Allow material to warm up to room temperature before opening container. It is important to resuspend any settled filler before using. Be careful not entrap air while mixing. 126-37 can be thinned with small amounts of CMI# 113-12 (fast drying), or #102-03 (slow drying) thinners.
