Description

PCB testing and fixing device

[ technical field ] A method for producing a semiconductor device

The utility model relates to a circuit board technical field especially relates to a PCB board test fixing device.

[ background of the invention ]

The PCB is also called a printed circuit board, and is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. It is called a "printed" circuit board because it is made using electronic printing. PCB boards have evolved from single-layer to double-sided, multi-layer, and flexible, and still maintain their respective trends. Due to the continuous development towards high precision, high density and high reliability, the volume is continuously reduced, the cost is reduced, and the performance is improved, so that the printed board still keeps strong vitality in the development engineering of future electronic equipment. The PCB needs to be tested after production is completed, but due to the fact that the sizes and the thicknesses of the PCBs in different batches are different, the PCB fixing jig needed in testing cannot be shared.

The utility model discloses it is not enough to solve prior art and research and propose.
