Abstract: A welding structure capable of rotational movement and a welding method for the same are introduced. The welding structure capable of rotational movement includes a seat member and a rotational movement member. The seat member has a welding portion. The rotational movement member is movably fitted to the seat member. The rotational movement member has a pressing portion for welding the welding portion to an object; thus, the rotational movement member undergoes rotational movement while the pressing portion is pressing against a pressed object, thereby causing displacement of the object. Therefore, the welding structure capable of rotational movement and the welding method for the same exhibit enhancement of ease of use, labor saving, and convenience.

Abstract: A soldering component and a method of fitting it to boards are introduced. The soldering component includes a body and a fitting portion. The fitting portion is fitted to an object. The body has an engaging portion with an elastic retraction space conducive to elastic retraction of two or more engagement portions, allowing the engagement portions to engage with another object. The soldering component has a weldable surface to be soldered to a weldable surface of the object. The weldable surface of the object has a built-in solder layer adapted to be heated for soldering the soldering component and the weldable surface of the object together. The soldering component is disposed in a carrier, taken out with a tool, compared with the object by a comparison device to determine a fitting position on the object, positioned at the fitting position with the tool, thereby being fitted to the object.

Abstract: A press-fit structure and a press-fit method are introduced. The press-fit structure includes a body, a pressurizing portion, a material storage space, a restricting portion and a limit stop portion. The pressurizing portion is for applying a pressure on an object to cause a material of the object to flow into or enter the material storage space. The object is restricted by the restricting portion, and a restriction direction of the press-fit structure is restricted by the limit stop portion. Thus, the press-fit structure and the press-fit method of the present disclosure are enabled to provide a required object with a stable assembly effect.

Abstract: 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.

Abstract: A fastening device includes a head member and a body member. The head member has a stem portion provided with a fastening section; and the body member is movably assembled to the head member and includes an elastic fastening section for engaging with a first workpiece. To connect the first workpiece to a second workpiece, simply fasten the fastening section of the stem portion to the second workpiece. To disconnect the first workpiece from the second workpiece, simply release the fastening section from the second workpiece. With these arrangements, it is able to quickly connect and easily disconnect two workpieces to and from one another.
