Abstract
A method comprises inserting a press-fit element into a through hole on a substrate board. The method also comprises obtaining a target heat-application plan for the press-fit element. The method also comprises applying heat to the press-fit element. The method also comprises determining that the target heat-application plan has been completed. The method also comprises withdrawing heat from the press-fit element.
Claims11
A method comprising:
- inserting a press-fit element into a through hole on a substrate board;
- obtaining a sensitive-component condition for a component on the substrate board;
- obtaining a target heat-application plan for the press-fit element;
- applying heat to the press-fit element;
- detecting that the sensitive-component condition has been reached at the component on the substrate board;
- triggering, based on the detecting that the sensitive-component condition has been reached, a sensitive-component alarm,
- determining that the target heat-application plan has been completed;
- and
- withdrawing heat from the press-fit element.
A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:
- obtain a target heat-application plan for a press-fit connection;
- obtain a sensitive-component condition for a component on a substrate board;
- activate a heating element to heat a press-fit element in a through hole on the substrate board;
- monitor a first temperature of the press-fit connection;
- monitor a second temperature of the component;
- detect, based on the monitoring the second temperature, that the sensitive-component condition has been reached at the component on the substrate board;
- trigger, based on the detecting that the sensitive-component condition has been reached, a sensitive-component alarm;
- determine, based on the monitoring the first temperature, that the target heat-application plan has been completed;
- and
- deactivate, based on the determining, the heating element.
