Soldering apparatus with calculation unit for obtaining information of its consumed electric energy

摘要

In a reflow soldering apparatus (100), air heated by heaters (12) is blown by fans (14,16) onto a printed circuit board (40). Temperature controllers (20) that control temperature of the heaters (12) supply operation amount thereof to a calculation unit (26) that calculates consumed electric energy of soldering apparatus (100). Inverters (22) that control revolution of fans (14,16) supply a value of current to the calculation unit (26). A control unit (24) supplies a coefficient of the consumed electric energy to the calculation unit (26). The calculation unit (26) calculates a total amount of consumed electric energy of the reflow soldering apparatus (100) based on the operation amount, value of current and coefficient of the consumed electric energy thus obtained. A display unit (30) displays on an operation screen the total amount of consumed electric energy of the reflow soldering apparatus (100), which has been calculated by the calculation unit (26).
