Abstract:
A method for attaching an electronic component to a substrate on which at least one of said electronic component and said substrate have solder predisposed on at least one contact member thereof, said process comprising:picking said electronic component from a supply source;transporting said electronic component from said supply source while simultaneously heating said electronic component;positioning said electronic component over a preselected site defined on said substrate while simultaneously heating said electronic component to a temperature sufficient to effect solder reflow of the solder predisposed on said at least one contact member of said at least one of the electronic component and the substrate;placing said electronic component on the preselected site defined on the substrate;simultaneously holding said electronic component on said preselected site defined on the substrate and interrupting the heating of said electronic component whereby the temperature of said electronic component drops to a temperature below said temperature sufficient to effect solder reflow and said solder becomes solidified; andsubsequently releasing the holding of the electronic component on the preselected site defined on the substrate.
