Abstract
A system includes a first module to store times and temperatures for phases in a profile to rework a populated printed circuit board (PCB) for a first integrated circuit (IC) on the PCB and a second module to store suggestions for modifying one or more of the times and the temperatures in the profile to generate a revised profile, the suggestions being associated with pass/fail indications determined from actual temperature information for the profile.
Claims15
A system, comprising:
- a first module to store times and temperatures for stages in a profile including solder heating stages to rework a populated printed circuit board (PCB) including removing a first integrated circuit (IC) on the PCB;
- an oven element to focus heat on the first integrated circuit during the rework of the PCB;
- a plurality of temperature sensing elements to detect actual temperature information associated with the first integrated circuit;
- and
- a second module to store suggestions for an operator to modify the times and/or the temperatures in the profile to generate a revised profile, the suggestions being associated with pass/fail indications determined from actual temperature information for the profile.
