Problems solved by technology

[0004] In the above-mentioned related technologies, the setting of the inner shield can make the electronic components have low electromagnetic interference and high electromagnetic tolerance. However, the inner shield needs to be formed by filling the groove with conductive glue. The conductive glue has poor fluidity and is not easy to fill the groove. Groove, the dispensing process is complicated, and defects such as voids and delamination are prone to occur, which not only affects the shielding effect of the inner shield, but also makes the shielding effect of the mutual electromagnetic interference between the electronic components inside the system-in-package module poor, and affects the shielding layer. The coverage effect makes the interference shielding effect between the packaged module and external electronic components poor

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a system-in-package module and terminal equipment. Background technique [0002] System-in-Package SIP (System In Package) integrates multiple functional chips and components into one package to achieve a complete function. SIP is a new type of packaging technology, which has the advantages of short development cycle, more functions, lower power consumption, better performance, lower cost and price, smaller volume and light weight. For complex SIP packages, the radio frequency and the main chip are integrated together, and the subsystems inside the package will also interfere with each other electromagnetically, so electromagnetic isolation must be carried out inside the package. [0003] In related technologies, the main method of electromagnetic isolation inside the package is to use sub-cavity shielding. There are several electronic components on the su...
