Copper bar

Copper bar

Semiconductor device connection bar

This is a semiconductor device connection bar made from a 3.0mm copper plate. After the cutting process is completed, hole processing for 9π and 6.5π, as well as tapping at three locations, will be performed. Next, chamfering will be done, and bending will be carried out with a bender, completing the main processing. A first inspection will be conducted, followed by a final inspection after nickel plating is completed. The production time, including the plating process, is estimated to be around 2 to 3 days.
