And secondly, crimping is performed by using a crimping tool, and the end head can be crimped by pushing the crimping tool through hydraulic pressure in the tool. Thirdly, sampling tension test is carried out after the bridging line is manufactured, and delivery is carried out after the test is qualified. The bonding wire is manufactured through the steps, only one surface of the indentation of the bonding wire terminal is found, and the bonding wire is often pulled out of the terminal integrally when a pull-out force test is carried out, so that the requirement of the pull test is not met, and unqualified products are easily caused.
