  • Patent number: 4752025
    Abstract: A repair terminal is disclosed for reworking defective components on printed circuit boards. The terminal has a heater arm which lowers itself over the component, and directs hot gas thereon. A vacuum shroud surrounds the heat zone around the component and removes excess heat so as to minimize damage to surrounding components. The heater arm has inner and outer tubes, the inner tube delivering hot gas the outer tube removing it. Thus the outer tube prevents an operator from being burned by the dangerously hot temperature of the inner tube. A workholder is also disclosed for holding and aligning the circuit board with the heater arm. The workholder is capable of adjustment along the X- and Y-axes as well as in the theta orientation.
