Weighted Distribution Constraint Based Prediction of Available Interval of Coaxial-to-Microstrip Flexible Interconnection

Space-Borne System-in-Package Based on High Reliability Microwave Interconnections

“…The coaxial seal can not only realize the transmission of high frequency microwave signals, but also realize the airtightness due to the dielectric filling between the internal and external conductive layers. Therefore, the coaxial seal is usually used to realize the transmission of microwave signals between the cavities in the microwave package and the external environment [11][12][13].…”

“…To solve this reliability problem, the coaxial seal and the substrate are usually connected by flexible structures such as wires and strips [13,14]. The interconnection modes mainly include core wire winding soldering [15], gold-ribbon lap bonding [16] and goldribbon wrap bonding [17].…”

“…The ABCD matrix [13] can be used to analyze the transmission characteristics of the gradually opening part in the air coaxial structure. It is set to be divided into n parts.…”

“…Therefore, the initial values of the diameter dd and length L 2 of the gradually opening air coaxial line can be calculated based on Equations ( 2)-( 4), ( 12), (13), and (15), and then the design can be completed by further optimization in the 3D electromagnetic simulation software, such as HFSS. Based on the parameters in the previous example, which are shown in Table 4, the initial values of the diameter and the length of the air coaxial line are calculated to be 0.7 mm and 0.5 mm, respectively.…”
