③ Paste your own job number.

5、 Inspection

① Appearance: whether the blanking core is too long; Winding quality of welding tape; Whether the terminal crimping is good, whether the plug-in terminal is inserted incorrectly or missing, whether the terminal falls off, and whether the insertion position is correct.

Test method: visual sample comparison.

② Size: whether the size is correct, and whether the sleeve is too long or too short.

③ Others: whether the use of fuse meets the requirements, whether the operation of each link meets the regulations, and whether the production process meets the requirements of customers.
