Product Information Sheet MATERIAL ID: EPO-TEK® 430 Date: 10/2006 Per: Rev: V Material Description: A two component, copper-filled, electrically and thermally conductive epoxy for adhesive bonding in electronics. It may be used at the PCB level for inter-connecting, grounding and EMI RF shielding. Fast curing at relatively low temperatures may be realized. Number of Components: Two Mix Ratio by weight: 100:2.5 Cure Schedule (minimum) 80°C/30 Minutes - 60°C/1 Hour Specific Gravity: --- Part A: 3.56 Part B: 1.02 Pot Life: 3 Hours Shelf Life: One year at room temperature - (viscosity will advance) NOTE: Container(s) should be kept closed when not in use. Filled systems should be stirred thoroughly before mixing and prior to use MATERIAL CHARACTERISTICS: To be used as a guide only, not as a specification. Data below is not guaranteed. Different batches, conditions and applications yield differing results; Cure condition: 150°C/1 hour * denotes test on lot acceptance basis PHYSICAL PROPERTIES: *Color (before cure): Part A: Brown Copper Part B: Amber Weight Loss: *Consistency: Thick paste @ 200°C: 0.18 % *Viscosity (23°C): @ 250°C: 0.27 % @ 1.0 rpm 300,000 - 400,000 cPs @ 300°C: 0.45 % Thixotropic Index: N/A Operating Temp: *Glass Transition Temp: = 110 °C (Dynamic Cure Continuous: - 55°C to + 250°C 20—200°C /ISO 25 Min; Ramp -10—200°C @ 20°C/Min) Intermittent: - 55°C to + 350°C Coefficient of Thermal Expansion (CTE): Storage Modulus @ 23°C: 608,362 psi Below Tg: 28 x 10-6 in/in°C Ion Content: Above Tg: 144 x 10-6 in/in°C Cl-: 33 ppm Shore D Hardness: 86 NH4+: 63 ppm Lap Shear @ 23°C: > 2,000 psi Na+: 5 ppm Die Shear @ 23°C: = 5 Kg / 1,700 psi K+: > 1 ppm Degradation Temp: 420 °C *Particle Size: = 50 microns ELECTRICAL AND THERMAL PROPERTIES: Thermal Conductivity: 1.34 W/mK Dielectric Constant (1KHz): N/A *Volume Resistivity @ 23°C: = 0.005 Ohm-cm Dissipation Factor (1KHz): N/A OPTICAL PROPERTIES @ 23°C: Spectral Transmission: N/A Index of Refraction: N/A EPOXY TECHNOLOGY, INC. 14 FORTUNE DRIVE, BILLERICA, MA 01821 (978) 667-3805, FAX (978) 663-9782 WEB SITE: www.epotek.com Document No. 43 Rev.
