Description

technical field [0001] The present application relates to the field of circuit technology, in particular to a printed circuit board transmission strip line and electronic equipment. Background technique [0002] With the development of science and technology, the application of electronic equipment is becoming more and more extensive. In the production process of electronic equipment, it is necessary to conduct high and low temperature reliability tests on electronic equipment, and the printed circuit board transmission belt line is a key component of electronic equipment. During the high and low temperature reliability test, due to the difference in expansion coefficient between the substrate layer in the printed circuit board transmission line and the metal cavity or metal plate used for the grounding function, the printed circuit board transmission belt will be damaged during the high temperature test. Problems such as cracking or deformation of the solder joints used to ...

AI Technical Summary

Problems solved by technology

It can be seen from the first aspect that in this embodiment, at least one groove is provided on one side of at least one first welding point to relieve the force on the at least one first welding point when the metal component expands, thereby solving the problem of printed circuit board Due to the different thermal expansion coefficients of materials in the transmission belt line, the deformation or cracking of the at least one first welding point does not need to add an additional material layer, thereby reducing the cost of the printed circuit board transmission belt line
