[Problem that the idea aims to solve]

However, the autoloader unit described above can be used instead of a ceramic substrate. When trying to convey the lead frame to the parts handler 15, the parts handler There was a problem that the positioning position at No. 15 was inaccurate. This is a lead frame. The reference part of the board is not the side surface like a ceramic board, but a hole or notch. It was because it was. To eliminate such problems, the transfer arm 10 should be made with high precision. It may be possible to form them at the same time, but doing so increases the cost. Also, When the lead frame is directly mounted on the parts handler 15, the lead frame becomes thin and flexible. The positioning operation must be performed carefully due to the visibility, and the positioning time is long. There was also the problem that it would take a while. If positioning takes time, the laser trimmer will stop for a long time. This results in a decrease in efficiency.
