F. buffers need to be filled between the inside of the carton and the PCB board
G. endurance specifications after carton sealing
H. maximum weight limit of each case

A. information that must be written outside the box: such as "shipping marks", P / N, version, cycle, quantity, origin country and other important information.
B. relevant quality certificates shall be attached, such as slice, weldability report, test record, and test reports required by customers. Place it in the way specified by the customer.
