Abstract: This article took the PC main board as a research object and simulated how to optimize the position of the desktop main board pads. The static stress analysis was executed using ABAQ -US/Standard. The objective was to reduce the local deformation of computer main board occurs when the connector was inserted and extracted during the assembly process, preventing the chips and capacitances on the main board from becoming invalid. The simulation results showed that the FEA method with Abaqus can be used to predict the main board performance and structure optimization.

Abstract: This paper has an explicit exposition on the study of waste PC-Main Board recycling by pyrolysis approach. The decomposing of PC-Main Board is completed above 400°C. For PC main boards around 77% solid residual (pyro-solid), 9 % pyro-oil and 14% pyro-gas were produced after the pyrolysis.The volatile detected by gas chromatography-mass spectrometry (PY-GC-MS) and the results indicated that:1) No significant influence of temperature on the products were observed over 400°C, only with the increase of temperature the small molecules volatile substance became a little high. 2) The characteristic pyrolysis products contained high concentrations of phenol, brom- phenol, while bisphenol A, tetrabromobisphenol A, methyl phenols, C1-C4 alkanes and alkanes were present.
