Description

Auxiliary jig for ECU printed circuit board Technical Field The utility model relates to the technical field of electronic equipment manufacturing, in particular to an ECU printed circuit board auxiliary jig. Background ECU (Electronic Control Unit) the printed circuit board is a core component of an electronic control unit, is widely applied to automobiles, industrial control and various electronic devices, and is used as a key link of device control logic and signal processing, and the processing quality and the processing precision of the printed circuit board have decisive influence on the overall performance and the stability of the device. In the processing process of the ECU printed circuit board, the use of the auxiliary jig is important for ensuring the processing efficiency and quality. Particularly in the core link of lead-free tin spraying, the conventional ECU printed circuit board auxiliary jig comprises a guide rail, a front air knife and a rear air knife, and the distance between the rear air knife and a rail is ensured through a specific structural design, so that the quality of lead-free tin spraying is improved to a certain extent. However, in the practical application process, such auxiliary jig gradually exposes obvious limitations. Specifically, the position setting of the front air knife and the rear air knife of the existing ECU printed circuit board auxiliary jig is relatively fixed, and the distance and the whole position of the existing ECU printed circuit board auxiliary jig cannot be flexibly adjusted. This defect results in the tool not being able to adapt to the circuit board processing of different size demands, greatly restricting the commonality and flexibility of the tool. When circuit boards of different specifications need to be processed, operators may need to replace different jigs or perform complicated adjustment, which not only increases the complexity of operation, but also reduces the processing efficiency. More serious, because the jig cannot be adapted to circuit boards with different sizes, inaccurate positioning in the processing process can be caused, so that uniformity and quality of tin spraying are affected, and potential risks are finally brought to the overall performance and reliability of the ECU printed circuit board. Therefore, in order to overcome the defects in the prior art, an auxiliary fixture for an ECU printed circuit board is urgently needed to solve the problem. The novel auxiliary jig can have the function of flexible adjustment so as to adapt to the processing of circuit boards with different size requirements, and simultaneously maintain or improve the quality and efficiency of lead-free tin spraying, thereby providing powerful support for the processing industry of ECU printed circuit boards. Disclosure of utility model The utility model aims to provide an ECU printed circuit board auxiliary jig, which solves the problems that the existing ECU printed circuit board auxiliary jig in the prior art is relatively fixed in position setting of a front air knife and a rear air knife, and the distance and the whole position of the front air knife and the rear air knife cannot be flexibly adjusted.
