Modelling of thermocouple geometry variations for improved heat transfer monitoring in smart electronic manufacturing environment

Original language description

In this paper, the effect of different thermocouple constructions are investigated from the aspect of reflow soldering, to achieve more precise soldering profile acquisition and failure analysis at different soldering heat transfer methods. The paper focuses on convection-based reflow and vapour phase soldering processes and related heat transfer coefficients. Different thermocouple constructions were investigated. The parameters involve ASTM-type (K, T, J), length of uninsulated wire length, insulation material (PFA, PVC, PTFE, woven glass-fibre), insulation thickness and dimensions of the hot-spot. The physical dimensions were obtained with optical microscopy for validation. Finite element analysis with multiphysics modelling (convection- and condensation-based heat transfer, and heat conduction in solids) was applied. After validation, the results show that most parameter and geometry changes – most significantly the uninsulated wire end – can result in non-negligible timely differences in 100 ms range between different sensors, pointing to the requirement of sorting and pairing in symmetric measurement environment. The results can be applied in modern manufacturing environment and in future process modelling and evaluation tasks.
