摘要:
An embedded type multifunctional integrated structure and a method for manufacturing the same are disclosed. The present invention utilizes the concept of multi-layer design to integrated more than two passive components on a component structure that would be adhered to a substrate. Hence, the embedded type multifunctional integrated structure has an OCP function, an OVP function, an anti-EMI function, and an anti-ESD function at the same time. Therefore, the present invention effectively integrated two or more than one passive components in order to increase function of the embedded type multifunctional integrated structure. Moreover, the present invention effectively reduces the size of the passive components on a PCB and reduces the number of solder joints.
