Process for depopulating a circuit board
Abstract:
Apparatus and methods for removing components from a circuit board. A conveyor transports circuit boards having components attached with solder through a heating section. When the solder has been melted by application of electromagnetic radiation, the circuit board is subjected to mechanical forces that dislodge the components to be removed from the circuit board. In one embodiment, the electromagnetic radiation is supplied by heaters operating at color temperatures in the vicinity of 973 Kelvin. The components are recovered in a form that allows their reuse.
