3 Terms and Definitions
The terms and definitions defined in GB/T 4146 (all parts), GB/T 19466.1, and GB/T 19466.3 apply to this document.
4 Principle
The differentially scanned calorimetric curves of the samples were measured by differential scanning calorimetry (DSC) on the heat-treated samples using a programmed temperature rise method.
The resulting peak melting temperature (Tpm) characterizes the bonding temperature of the sample.
5 Instruments and Tools
5.1 Differential Scanning Calorimetry (DSC), the main performance is as follows.
a) It can increase the temperature at the same rate of 0.5°C/min~20°C/min;
b) Keep the test temperature constant within ±0.5°C for at least 60 minutes;
c) The ability to heat up in stages or warm up in other modes;
d) The gas flow rate is in the range of 10mL/min to 50mL/min, and the deviation is controlled within ±10%;
e) The resolution of the temperature signal is within 0.1°C and the noise is below 0.5°C;
f) The instrument can automatically record the DSC curve and integrate the area between the curve and the baseline, with a deviation of less than 2%;
g) Sample holder assembly with one or more sample holders.
5.2 Specimen dish. stainless steel, able to seal and withstand the overpressure generated during the measurement process.
5.3 Analytical balance. 0.1mg.
5.4 Standard sample. Indium, melting temperature 157°C, purity ≥99.9%; tin, melting temperature 231°C, purity ≥99.9%.
5.5 Air source. Nitrogen, purity ≥99.99%.
5.6 oven. temperature control accuracy ± 3 °C, temperature fluctuations ± 1 °C.
