Abstract: An electronic seal includes a main body, an insertion bolt, and an identification circuit. Thus, the electronic seal has a determined identification code so that the identification host can rapidly identify the article (or storage space) sealed by the electronic seal, and the sealed article is identified and managed easily and conveniently by provision of the electronic seal, thereby saving the manual work.

Abstract: A testing probe including a shaft body and a plurality of claws is provided. Each cross section of the shaft body has a substantially identical shape and a substantially identical outer diameter. The claws are formed integrally with the shaft body at an end thereof. An orthogonal projection of the claws on any one of the cross sections of the shaft body is within the contour of the cross section. Contacting a solder bump on a test pad of a circuit board with the claws of the testing probe increases the test yield of the circuit board.

Abstract: A local temperature control fixture suitable for a circuit board is provided, and the circuit board has at least a first heat-receiving region. The fixture includes a heat-insulating board. The heat-insulating board is positioned over the circuit board suitably and has at least a first exposing region whose projection on the circuit board is superposed with the first heat-receiving region. Furthermore, by means of the local temperature control fixture, components on the circuit board can be properly heated according to the volumes thereof so as to melt solder between the components and the circuit board. Therefore, the components in different sizes are firmly soldered onto the circuit board.
