If the electric core is the substandard product electric core, then control first manipulator and directly abandon electric core, that is to say, do not have the substandard product electric core of protection glue film and no longer place and carry on defeated material mechanism and carry out flattening and short circuit test on next step. So, first manipulator only will have the certified products electricity core of protection glue film and place on defeated material mechanism and carry to carry out next step flattening and short circuit test.
