Definitions

  • time-series temperature distribution data may be expressed in correspondence with the electronic component 12 mounted on the soldered workpiece 10 instead of expressing the upper surface of the workpiece 10 to be soldered with a two-dimensional matrix. For example, if time-series temperature distribution data is generated from a temperature distribution image signal of a temperature distribution image of 30 images taken at intervals of 0.1 seconds for a workpiece 10 to be soldered on which four electronic components 12 are mounted. The time change of the temperature distribution of the workpiece 10 to be soldered is expressed as a 4 ⁇ 30 three-dimensional matrix.
  • step S50 a step of determining whether the electronic component 12 is soldered to the workpiece 10 to be soldered and determining whether the maintenance work of the soldering apparatus 100 is necessary is performed.
  • the monitoring determination unit 62 calculates the temperature difference by comparing the data of the corresponding divided regions in the master data accumulated in the storage unit 63 and the time-series temperature distribution data generated in step S40. Then, the monitoring determination unit 62 determines whether or not the temperature difference is within a predetermined allowable temperature difference range by comparing the temperature difference and the allowable temperature difference range.
  • the allowable temperature difference range is a criterion for determining the soldering state, and is information indicating the allowable temperature difference range, and is stored in the storage unit 63 in advance.
  • an appropriate value preset in the monitoring determination unit 62 can be used as the adjustment instruction value of the device control parameter.
  • the electronic component 12 may be damaged.
  • the first peak temperature P1 and the second peak temperature P2 are too low, the soldering of the electronic component 12 fails.
  • the peak temperature time PT is too short, it is considered that at least one of the primary jet 86 and the secondary jet 87 is weakened.
  • the peak temperature time PT is too long, it is considered that at least one of the primary jet 86 and the secondary jet 87 is too strong.
  • the melting point of lead-free solder is about 200 ° C. or more and 230 ° C. or less.
  • the allowable range of peak temperature differs for each electronic component 12, and the case where the allowable range of peak temperature exists below 200 ° C. It is also conceivable that the range exists at 230 ° C. or higher. This is because the temperature measured by the thermo camera 5 is the upper surface of the workpiece 10 to be soldered, not the lower surface where the terminals 13 of the electronic component 12 to be soldered are present. For this reason, the temperature of the upper surface of the workpiece 10 to be soldered measured by the thermo camera 5 may be lower than the temperature of the lower surface where the terminal 13 of the electronic component 12 is present and the molten solder 85 is sprayed.
