The X-ray spectrum of the rim of non-thermal shells consists in general of thermal and nonthermal components. Such emission is therefore the most informative for analysis of the electron thermalization and acceleration processes. In this work, we present preliminary results on the analysis of 30 narrow regions covering the whole outer shock rim of the shell of SN1006, selected in the XMM-Newton archive observations of this remnant. Two different approaches to analyzethe spectra are applied that allows us to cross-check the best- fit models. Our results will complement previous studies on the non-thermal component with information on the thermal emission and vice versa. The constraints which can be put on the level of electron-ion equipartition and on the electron injection effciency with this kind of analysis are also discussed.
