Abstract:

A dummy electronic assembly without electronic components was used to measure loadings and deflections caused by 0.2, 0.3, 0.4, 0.5 and 0.6 gcm3 densities of polystyrene bead foam during fusion and thermal cycling. Previously developed and proven transducers showed that the lower three densities caused low and safe loads and deflections, but that the highest two densities must be used with care for fragile electronic components.
