TMA Testing for PCB CTE and Glass Transition Temperature

Thermomechanical Analyzer

Core Function: The TMA (Thermomechanical Analyzer) evaluates sample expansion or contraction over a wide temperature range
Advanced Testing: Performs creep, stress relaxation, and stress-strain measurements in a single instrument
Temperature Range: -170°C to 600°C (TMA7100) / up to 1500°C (TMA7300, with alumina furnace)
High Sensitivity: 0.01 μm resolution with a ±5 mm TMA measurement range

Application: TMA thermomechanical analysis tests PCB substrate CTE to evaluate dimensional stability under temperature changes. (New Machine)
