Technical Field

[0001] The utility model relates to the technical field of circuit board detection, in particular to a fixing detection tool for micro-pitch circuit boards. Background Art

[0002] A micro-pitch circuit board is an electronic component assembly substrate with micro-pitch circuits, and its circuit spacing is much smaller than that of traditional circuit boards. The emergence of miniaturized circuit boards has greatly promoted the miniaturization, lightweight and high performance of electronic equipment. The design, manufacture and application of micro-pitch circuit boards involve a series of complex processes and technologies, such as photolithography, etching and copper plating. The selection and precision of these technologies have a decisive influence on the quality and performance of micro-pitch circuit boards. After the micro-pitch circuit boards are produced, they must be tested to ensure the quality and stability of the circuit boards, thereby ensuring the performance and quality of the final products.

[0003] During the detection process, the micro-pitch circuit board is first placed in the detection template, and then it needs to be connected to specific points on the circuit board through contact probes or electrodes for detection. However, the detection template is prone to slight shaking due to external factors during the detection, which may cause deviation in the contact of the detection probe, affecting the precision and accuracy of subsequent detection. In addition, the shaking of the detection template may easily damage the probe that contacts the circuit board. Utility Model Content

[0013] Compared with the prior art, the utility model provides a tooling for fixing and detecting micro-pitch circuit boards, which has the following beneficial effects.

[0014] 1. The utility model sets a positioning component, a fixing component, a spring and a circular groove to cooperate with each other. The positioning component can be used to position the detection needle plate and the detection template, so that the detection template and the detection needle plate can be accurately docked together when they are combined to achieve accurate positioning and fixation. Then, the upper cover plate is covered on the detection template. Under the action of the circular groove, the upper cover plate completely embeds the detection template. At this time, the spring always pushes the detection template to move, and then cooperates with the fixing component to limit and fix it, so that the detection template is firmly limited and the detection probe is protected from damage, thereby ensuring stability and accuracy during the detection process.
