Abstract
A desoldering tool and control system including enhanced features for detecting solder clogging as well as on-delay and sleep mode functions to enhance the life of the desoldering tool components.
Claims28
A desoldering system, comprising:
- a controller including a vacuum pump, a power supply system, a pressure sensor, a display and control circuitry including operation and clog detection programs;
- a desoldering tool including a heater assembly, a filter chamber and a removable filter assembly and an on/off trigger switch;
- said controller measuring a vacuum pressure and displaying a degree of the vacuum pressure for identifying a status of a clog or blockage;
- and
- a cable and vacuum conduit removably interconnecting said controller and said desoldering tool.
2 more elements
A desoldering system, comprising:
- a controller including a vacuum pump, a power supply system, a pressure sensor and control circuitry;
- a desoldering tool including a heater assembly, a filter chamber and a removable filter assembly and an on/off trigger switch;
- and
- a cable and vacuum conduit removably interconnecting said controller and said desoldering tool;
- and
- said controller further comprising a sleep mode program for limiting power to said desoldering tool that is terminated by an operation of said on/off trigger switch.
3 more elements
A desoldering system, comprising:
- a controller including a vacuum pump, a power supply system and control circuitry including a vacuum pump on-delay and user selectable and adjustable vacuum pump off-delay programs;
- a desoldering tool including a heater assembly, a filter chamber and a removable filter assembly and an on/off trigger switch;
- and
- a cable and vacuum conduit removably interconnecting said controller and said desoldering tool.
1 more element
A removable filter assembly for a desoldering tool, said desoldering tool including a heater assembly and a filter chamber sized to receive said removable filter assembly, said removable filter assembly comprising:
- a chamber element having a forward end and a proximal end;
- a front holder mounted to said forward end of said chamber element, said front holder including an orifice;
- a solder collector locate in the proximal end of said chamber element, said solder collector secured to a mounting base and said solder collector having a generally cone shaped cross section with a large end of said cone open and facing said orifice of said front holder whereby liquefied solder entering said chamber element through said orifice solidifies onto said solder collector;
- and
- a filter holder on said proximal end of said chamber element.
