Abstract: A circuit board device includes one or more slots formed in a board, and one or more fastener members having one or more projections engageable into the slots of the board, to anchor the fastener member to the board, and to prevent the fastener member from moving relative to the board while welding the fastener member to the board with one or more solders. One or more electronic components may then be precisely and easily aligned with and secured to the fastener members with the other fastener members. A solder member may be applied on the board for securing to the solders.

Abstract: An electrical device includes an electrical device body, a stand foot component and a resilient member. The electrical device body has a stand foot holder. The stand foot holder has two opposite sides each formed with a first pivotal portion. The stand foot holder further has a first slide-connecting portion between the first pivotal portions. A concave portion is formed in the first slide-connecting portion. The stand foot component is mounted in the stand foot holder and has two opposite sides each formed with a second pivotal portion pivotally connected with the first pivotal portion. A second slide-connecting portion, which may slide relative to the first slide-connecting portion, is formed between the second pivotal portions. A convex portion is formed in the second slide-connecting portion. When the stand foot component is held in the stand foot holder, the convex portion sinks into the concave portion.
