摘要: A detonator assembly method wherein a base charge is placed into a tube to abut a closed end of the tube, an electronic module is positioned inside the tube, a displacement member with a stop formation is used to move the module, against a frictional restraining force, to a location at which the stop formation abuts a rim of the tube and wherein the module is held in position by deforming the tube into engagement with the module.
