In the Semiconductor Chip Thermal Testing & Packaging industry, precise temperature control is essential for device reliability, package integrity, and repeatable electrical performance. From temperature cycling and burn-in to underfill cure, mold-temperature control, and thermal chamber operation, manufacturers rely on heat transfer fluids that can respond quickly across both sub-zero and elevated process windows. Industry testing commonly spans low temperatures down to-70°C or belowand high temperatures up to125–150°Cfor reliability screening and burn-in, making low-viscosity circulation and thermal stability critical.EuroTherm 200 (E200)offers a-85 to 230°Crange with1.20 mm²/s viscosity at 40°C, supporting rapid low-temperature response and long service life.EuroTherm 230 (E230)covers-60 to 230°Cwith1.90 mm²/s viscosity at 25°C, delivering dependable thermal stability for packaged-device testing loops. For wider integrated heating-and-cooling duty,EuroTherm 280 (E280)provides-100 to 220°Cservice,1.0 mm²/s viscosity at 40°C, and apour point below -110°C, ideal for extreme cycling systems. Silicone-basedSi-05andSi-10further broaden process flexibility with-80 to 280°Cand-60 to 300°Cperformance, plus4.0and7.9 mm²/s viscosity at 40°Crespectively, helping semiconductor facilities improve temperature uniformity, reduce thermal stress, and maintain high-throughput packaging consistency.
