ABSTRACT:
A system for removing protective coatings from a circuit board assembly. The system includes a tool for removing protective coatings from a circuit board assembly. The tool has a flow head, which includes a support, having an opening which is adapted to contact the circuit board assembly and flow solvent to the surface of the circuit board. The flow head may also include a solvent nozzle positioned within the support. The solvent nozzle has an opening adapted to apply solvent to the circuit board assembly. The flow head also includes a solvent recovery volume positioned beneath the support and adjacent to the nozzle. The system also includes a second solvent reservoir, a mechanism for applying heat to the reservoir, and a mechanism for circulating solvent from the reservoir to the flow head and back to the reservoir.
