Problems solved by technology

For the typical interconnection between circuit modules in microwave components, the traditional direct soldering rigid connection is replaced by the gold ribbon bonded interconnection structure with arched and curved shape, which can buffer the interconnection itself and the external load it bears. This flexible structure The reliability of the interconnection is greatly improved, but due to the initial irregular configuration of the gold ribbon bonding interconnection, and this configuration is more susceptible to deformation due to environmental loads, these change the discontinuity of the signal transmission path, which will affect the high The transmission performance of high-frequency microwave signals is significantly affected, and the change of the interconnection shape parameters has great uncertainty, which in turn causes the uncertainty of signal transmission after the interconnection
In the existing literature, there are few reports on the impact mechanism of interconnection form and signal transmission performance. However, engineering mostly stays on manual experience and a large number of software simulations, which cannot accurately and effectively realize signal transmission performance prediction and regulation, resulting in high labor costs. , and the work efficiency is low
