Description

Technical Field

[0001] The present invention relates to the technical field of PCB production, and in particular to a supporting device for PCB production. Background Art

[0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Printed circuit boards are often represented by "PCB" instead of "PCB boards". It has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, improves the level of automation and production labor rate. According to the number of layers of the circuit board, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. Since printed circuit boards are not general terminal products, the definition of the name is slightly confusing. For example: the motherboard used in personal computers is called the mainboard, and cannot be directly called a circuit board. Although there is a circuit board in the motherboard, it is not the same. Therefore, when evaluating the industry, the two are related but cannot be said to be the same. For example: because there are integrated circuit parts loaded on the circuit board, the news media calls it an IC board, but in fact it is not equivalent to a printed circuit board. The printed circuit board we usually refer to is a bare board-that is, a circuit board without components.

[0003] There are more and more types of existing PCB boards, and their thicknesses are also different. Traditional PCB board production support racks are mostly fixedly arranged for PCB boards, which is not convenient for transporting PCB boards of different thicknesses.
