Description

Technical Field

[0001] The utility model relates to the field of circuit boards, in particular to a spliced printed circuit board. Background Art

[0002] As the name suggests, circuit board panelization involves joining multiple circuit boards together to form a large set. The significance of circuit board panelization lies in, first, facilitating subsequent soldering and mounting of circuit boards for customers; second, it increases board utilization, thereby reducing production costs. Because each industry's products vary, the sizes of the PCBs used vary. Some electronics industry PCBs are relatively small, often designed as panelization. This not only facilitates processing and production at electronics factories, but also reduces board waste and lowers costs. Existing circuit board panelization uses a special-shaped notch to connect two different circuit boards. However, this method only allows for two-dimensional fixation of the two boards, preventing lateral and vertical offset, and cannot achieve vertical fixation. To address this issue, we have proposed a spliced printed circuit board. Utility Model Content
