3 Soldering iron temperature test When the product is on the line, the soldering iron of the welding station is tested for temperature, and adjusted to the required temperature as required, and the record is archived after adjustment.
4 Electric batch torque test Torque test of the electric batch of the assembly station during mass production, and adjust to the appropriate torque according to the torque standard, ensure that the screw can be hit in place and will not slip, and record and archive after adjustment.
5 Semi-finished product aging When the product is assembled into a semi-finished product, the product is subjected to the aging test to ensure the reliability of the product. The semi-finished product is aged for 4 hours, and the aging method is impacted by aging.

After the confirmation is completed, the aging can be ended for the next production.
7 Constant temperature and humidity assembly After the aging of the semi-finished products, the products will be assembled in the constant temperature and humidity workshop, and the electric batch will be tested and set before the assembly.
8 High-pressure waterproof test Perform a high-pressure waterproof test on the assembled product, firstly protect the product against scratches, then test and set the test pressure. After the standard test time is reached, check whether the product is waterproof or not, and the non-conforming product is returned for repair.
9 Finished product aging Perform product aging test on products that have passed the waterproof test to further ensure product reliability. The finished product is aged for 4 hours, and the aging method is impacted by aging.
