A structure and method for retaining fastening element solder are introduced. The structure includes a fastening element which has a solderable surface and a fastening portion or a hole portion. One end of the hole portion or the fastening portion has a retaining portion. During a soldering heating process, solder flows into or enters the retaining portion to cool down and solidify. The solidified solder is retained in the retaining portion. The fastening element is firmly coupled to a first object because of coordination between the solderable surface and the retaining portion, and the second object is coupled to or removed from the fastening element because of coordination between the fastening portion and the hole portion, so as to couple together and separate the first and second objects repeatedly and quickly.

The first trace includes a first circumventing part configured to circumvent the fixing part; and the second trace includes a second circumventing part configured to circumvent the fixing part and having a directional component different from the first direction.

Portable electronic devices by their nature are designed to be regularly physically repositioned and relocated, which can cause significant mechanical stresses on internal components, including printed circuit boards (PCBs). This is particularly true when a portable electronic device is handled roughly. These significant mechanical stresses can cause threaded mechanical fasteners securing the PCBs to become dislodged. A dislodged threaded mechanical fastener may contact electrically conductive features of the PCB or other internal components, thereby causing a ground fault or short. At a minimum, this may cause the portable electronic device to not work well, or at all. Further, this may cause the portable electronic device to overheat and become a fire hazard. The presently disclosed technology detects if the threaded mechanical fasteners within a portable electronic device become dislodged. A user of the portable electronic device may then be warned, and the portable electronic device may be powered down.

A method of assembling a fastener structure on a plate body is introduced. The fastener structure includes a body portion and a fastening body. The body portion has a solderable layer, and the solderable layer is soldered to a plate body. The fastening body combines movably with the body portion. The fastening body has a head and a fastening portion. The body portion or the fastening body is provided on the plate body for soldering after it is picked up by a tool so that the body portion can combine with the plate body. Also, the body portion or the fastening body combines with an assisting pickup unit, and the fastener structure is provided on the plate body for soldering after it is picked up by a tool through the assisting pickup unit so that the body portion can combine with the plate body.
