The system of the present invention provides a pair of assembly modules for assembling electronic components to a series of printed circuit boards or like substrates. The pair of assembly modules are operatively connected in series, and each module includes a pair of assembly stations operating in parallel within the module. Means are provided to bypass the first assembly module and deliver unpopulated substrates to the second module for processing, while simultaneously bypassing the second assembly module with substrates populated by the first assembly module. In the event that one of the assembly stations of either assembly module is inoperative, it may be bypassed and the assembly of its electronic components redistributed to the remaining, operative assembly stations to optimize the productivity of the system.
