1. A method for transfer fluxing, comprising the following steps in the following order:

  • loading a product program;

    acquiring a fluxing tool comprising a flux reservoir on a first robot head of an automated component placement machine;

    attaching a compliant pad to an opening in the flux reservoir;

    controlling the deposition of flux onto the complaint pad;

    acquiring a component on a second robot head of the automated component placement machine;

    identifying a target placement location for the component on a substrate;

    identifying a position of the component on the second robot head;

    determining a component placement site for the component on the substrate based on the identifying of the target placement location on the substrate and on the identifying of the position of the component on the second robot head;

    moving the first robot head carrying the fluxing tool to the component placement site;

    applying flux to the component placement site with the fluxing tool;

    placing the component on the substrate using the second robot head; and

    determining if additional components need to be placed and, if so, repeating the steps from acquiring the component; and

    if not, ending the process.
