Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to a multi-size PCB board testing device. Background Technology

[0002] PCB, or Printed Circuit Board, is a crucial component of the electronics industry. Almost every electronic device, from small items like watches and calculators to large systems like computers, communication devices, and military weapons, relies on PCBs for electrical interconnection with integrated circuits and other electronic components. A PCB consists of an insulating substrate, connecting wires, and solder pads for mounting and soldering electronic components. It serves the dual purpose of conductive lines and an insulating substrate, replacing complex wiring to achieve electrical connections between components. This simplifies the assembly and soldering of electronic products, reduces the workload of traditional wiring methods, and significantly reduces the labor intensity of workers. However, during PCB production, dimensional inspection is required. Traditionally, this involves workers using measuring tools to measure the length, width, and height of the PCB sequentially.

However, the detection is only performed manually with scale, which cannot guarantee the detection accuracy. In view of this, a multi-size PCB board detection device is proposed.
