Claim Text:
1. A method performed by a handheld soldering iron station for a soldering joint connection validation, the handheld soldering iron station including a soldering cartridge having a soldering tip, the method comprising: identifying a type of the soldering cartridge being used by the soldering iron station and obtaining information related to the identified cartridge; determining that a soldering event has started by measuring a power level delivered to the soldering tip, within a first predetermined time period; performing a preliminary validation by measuring a soldering tip temperature, after the soldering event has started; monitoring the power level delivered to the soldering tip to detect liquidus occurrence; determining a thickness of an intermetallic component (IMC) of the soldering joint as a function of soldering time and soldering tip temperature, after detect the liquidus occurrence; determining whether the thickness of the IMC is within a predetermined range, within a predetermined cooling time period; and indicating that a reliable soldering joint connection is formed, when the thickness of the IMC is within the predetermined range, within the predetermined cooling time period.
