Description

PCBA board support frame

Technical Field

The utility model relates to a tool field especially relates to a PCBA board support frame.

Background

The jig is a tool for carpenters, ironmen, pliers, machines, electronic controls and other handicrafts, and is mainly used as a tool for assisting in controlling positions or actions (or both). The jig can be divided into a process assembly type jig, a project test type jig and a circuit board test type jig.

A Printed Circuit Board (PCB), which is called a Printed Circuit Board (PCB) for short, is one of important parts in the electronic industry. Almost every kind of electronic equipment, as small as electronic watches, calculators, as large as computers, communication electronics, military weaponry systems, requires printed boards for electrical interconnection as long as there are electronic components such as integrated circuits. In the course of research on larger electronic products, the most fundamental success factor is the design, documentation and manufacture of the printed boards of the products. The quality of printed board design and manufacture directly affects the quality and cost of the whole product and even results in a success or failure of commercial competition. A Printed Circuit Board Assembly (PCB) Board, i.e., a PCB Board blank, is subjected to SMT (Surface Mount Technology) Assembly, and then subjected to a DIP (Dual Inline-pin Package) Assembly process, i.e., a PCB Board with electronic components soldered and assembled thereon.

Electronic components are attached to the front side and the back side of a plurality of PCBA boards, when a table board is placed for inspection or components are required to be welded and maintained, if a supporting table is not used, the components facing the working table are easy to damage the components due to the fact that the components touch the table board, and due to the fact that the sizes and heights of the partially attached components are different, the components are easy to incline when placed, and inspection and maintenance are inconvenient. In order to avoid damaging the component on the surface contacting the table board, a specific jig is required to hollow out the downward part or a customized standard clamping jig is used for supporting the bottom.

If use standard customization screens saddle, because PCBA board size is different, the trompil size on the PCBA board is different or can be blocked the position of difference, so can only one-to-one use tool, increased the cost of doing the tool number of pieces like this.
