The disadvantage is that OP300 check out because the same events occurred because after spraying Datum deformation results in a more serious position deviation
This disadvantage is in the OP300 test out, the cause is the same as the cause, after the spray Datum deformation caused by the position degree deviation more serious
This disadvantage is detected in op300, the same reason is the same as the cause, and the datum deformation causes more serious positional deviation during spraying<br>
