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 filter, 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 nozzle, 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 as being located between said nozzle and said filter chamber of said desoldering tool or said clog or blockage being located at a filter within said controller;
- a cable and vacuum conduit removably interconnecting said controller and said desoldering tool;
- and
- a vacuum conduit port assembly having a cap, a filter and a filter support, said clog detection program provided for further determining if a clog or blockage is located at said filter of said vacuum conduit port assembly or at said desoldering tool.

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 and after the sleep mode program is terminated, a control program in the controller allows the vacuum pump to operate only when said on/off trigger switch is depressed and a heating element of said heater assembly and a nozzle reach a set temperature.
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 wherein said controller further comprises a sleep mode program for limiting power to said desoldering tool after an off-delay period that is terminated by the operation of said on/off trigger switch;
- and
- a cable and vacuum conduit removably interconnecting said controller and said desoldering tool.

A desoldering system comprising:
- a controller including a filter, 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 nozzle, 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 as being located between said nozzle and said filter chamber of said desoldering tool or said clog or blockage being located at a filter within said controller;
- a cable and vacuum conduit removably interconnecting said controller and said desoldering tool;
- wherein said clog detection program receives input from said pressure sensor positioned proximate said vacuum pump, and determines the location of the clog by:
- waiting a first period after activation of said vacuum pump to determine the pressure at said pressure sensor;
- waiting a second period after said first period to make a second determination of the pressure at said pressure sensor;
- comparing said first pressure to said second pressure;
- and
- determining the location of the clog of the system based upon the comparison of said first pressure to said second pressure.

A desoldering system, comprising:
- a controller including a filter, 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 nozzle, 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, said controller provides a visual display of the degree of clogging or blockage on said display, the display corresponding to a measured negative pressure measured at a piezoelectric sensor having a voltage output that is converted to the output to said display in said controller;
- and
- a cable and vacuum conduit removably interconnecting said controller and said desoldering tool.
