Abstract

The invention discloses an SIP packaging structure based on an embedded integrated pull-up and pull-down resistor IPD, and belongs to the field of packaging integration. The structure comprises a packaging substrate, a chip and a printed circuit board. An embedded integrated pull-up and pull-down resistor IPD is embedded in the packaging substrate to complete pull-up and pull-down functions of various different levels; the chip is mounted at the top of the packaging substrate; the printed circuit board is installed at the bottom of the packaging substrate. According to the embedded integrated pull-up and pull-down resistor IPD, pull-up and pull-down bias of a chip circuit port can be realized, the port of the chip is interconnected with a power supply end and a ground end, special design can be carried out according to different requirements, and the connection mode cannot be changed after being fixed. According to the SIP packaging structure based on the embedded integrated pull-up and pull-down resistor IPD, linear pressure can be reduced to a great extent, and the number of wiring layers is reduced; meanwhile, the size of the pull-up resistor and the pull-down resistor in the SIP is almost reduced, and the requirements for miniaturization, light weight and generalization of the SIP are well met.

Description

Technical field [0001] The present invention relates to a package integration technology, and particularly relates to a packaging structure for a SIP based on the pull-down resistor embedded integrated the IPD. Background technique [0002] As integrated circuit manufacturing technology to smaller process node development, and functional requirements of the system toward a more powerful development, design of the entire system on a single integrated circuit chip becomes more challenging, SiP is becoming an alternative. [0003] In order to meet the growing requirements of system functions, integrated into the SiP in the bare number of chips is also rising, the number of pull-down resistor matching is also increasing, to the SiP traces and miniaturization has brought more pressure . Inventive content [0004] Object of the present invention is to provide a pull-down resistor based SIP package IPD embedded integrated on to address the current SIP systems increasingly difficult to ...
