Abstract
A pressure gauge or monitor is attached to a soldering iron so that the pressure with which the iron is being applied can be precisely monitored. Such a pressure monitor on a soldering iron can be used to monitor the pressure applied with the soldering iron when forming a solder electrode on an anti-reflective film of a cathode ray tube. This allows such electrodes to be consistently and optimally formed for grounding the anti-reflective film.
Claims22
A soldering iron in combination with a pressure monitor, said combination comprising:
- a soldering iron having a soldering tip;
- and
- a pressure monitor mounted on said soldering iron, said pressure monitor monitoring a pressure with which said soldering iron is applied;
- wherein said pressure monitor comprises a spring that is compressed in correspondence with said pressure of said soldering iron;
- and
- wherein said pressure monitor further comprises a gauge with a needle that is deflected along a numeric scale in correspondence with compression of said spring.
A method of forming a solder electrode on an anti-reflective film of a cathode ray tube, said method comprising:
- monitoring a pressure applied with a soldering iron that is forming said solder electrode;
- and
- maintaining said pressure within a pre-determined optimal range;
- wherein said monitoring said pressure further comprises compressing a spring on said soldering iron in correspondence with said pressure applied;
- and
- wherein said monitoring said pressure further comprises deflecting a needle of a pressure gauge along a numeric scale in correspondence with compression of said spring.
A device for forming a solder electrode on an anti-reflective film of a cathode ray tube, said device comprising:
- means for monitoring a pressure applied with a soldering iron that is forming said solder electrode, wherein said means for monitoring said pressure further comprises a spring on said soldering iron that is compressed in correspondence with said pressure applied;
- means for maintaining said pressure within a pre-determined optimal range;
- and
- means for visually indicating said pressure based on compression of said spring, wherein said visual indication means further comprises a needle of a pressure gauge deflected along a numeric scale in correspondence with compression of said spring.
A method of forming a solder electrode on an anti-reflective film of a cathode ray tube, said method comprising:
- forming an anti-reflective film on a cathode ray tube;
- with a soldering iron, forming a solder electrode on said film;
- monitoring a pressure applied by said soldering iron that is forming said solder electrode;
- and
- maintaining said pressure within a pre-determined optimal range based on said monitoring;
- wherein said monitoring said pressure further comprises compressing a spring on said soldering iron in correspondence with said pressure applied;
- and
- wherein said monitoring said pressure further comprises deflecting a needle of a pressure gauge along a numeric scale in correspondence with compression of said spring.
