Problems solved by technology

Therefore, traditional soldering stations, which had only one power output level, did not optimize the functionality of the different cartridge tips available in the market.
However, even these new technologies encountered serious shortcomings.
As a result, the sensed temperature of the heating element within the cartridge did not reflect the true temperature of the tip.
Second, because of the distance between the sensor and the tip, the temperature gradient between the sensor and the tip could often be steep.
Although the user skill level required to measure and to calculate the difference was certainly lower than that required to adjust the dials, the process still expended valuable time.
A more significant issue involved the removal of a cartridge having a given tip configuration from the connector and the replacement with a cartridge having a different tip configuration.
For example, if the tip temperature is not adjusted to the proper level, the soldering iron is operable to solder an application or type of solder even though the setting is unsuitable for the application or type of solder.
If soldering is performed at an inappropriate temperature, the electronic component to be soldered may be damaged by the excessive heat or the solder connection could be weak if the tip was either not hot enough or too hot.
This increases the average cost of goods and decreases profit margins.

Abstract

An automated soldering system with an intelligent power supply that can automatically configure the power output to interchangeable soldering cartridges, where the soldering cartridges include readable information to allow the power supply to properly power the cartridge to achieve a desired, entered operating temperature. The system includes a cartridge with an identifier that contains information particular to that cartridge, a reader able to read that information, and an indicator positioned on a connector into which the cartridge is inserted.

Description

[0001] 1. Field of the Invention:[0002] The present invention relates to an automated soldering system with an intelligent power supply that can automatically configure the power output to interchangeable soldering cartridges, where the soldering cartridges include readable information to allow the power supply to properly power the cartridge to achieve a desired, entered operating temperature. In particular, the present invention encompasses the use of an identifier on the cartridges and a reader coupled to the power supply for immediate recognition of the type of soldering cartridge to be used. In addition, to inform the user that the station is operational, a LED indicator preferably located proximate to the interchangeable cartridge and activated by the automated soldering system displays various light signals for the user.[0003] 2. General Background and State of the Art:[0004] Soldering stations have been in use for many years. The typical soldering station includes two compon...
