ければならず、甚だ手間隙のかかるものであった。By the way, in the above method of manufacturing the lead pin with brazing material, when various types of lead pins 3 are sequentially fed to the carbon jig 1, the pins having different pin sizes are mixed and fed. This is carbon jig 1
When it is inserted into the large number of holes 2 of the above, the lead pin 6 with the brazing material 5 mixed with different sizes is made. The state of the brazing material 5 after brazing in the furnace can be inspected from above the carbon jig 1, but it cannot be inspected because the difference in pin size is hidden in the hole 2 of the carbon jig 1. Therefore, when inspection is required, it is necessary to inspect each of the lead pins 6 with the brazing material 5 discharged from the holes 2 of the carbon jig 1 one by one, which is very time consuming.
