Abstract: This paper demonstrates a design of high integrated and miniaturized multi-core general-purpose control computer module, which can be implemented through the system-in-packaging (SiP) technology. This module integrates nine large-scale integrated circuits, including multi-core DSP, FPGA, SDRAM, and Flash. It employs a high-temperature co-fired ceramic (HTCC) tube shell and utilizes a double-sided dual-cavity layout packaging design technology to achieve miniaturization, generalization, and high-density integration of complex system circuits. Additionally, to address issues such as the integrity of high-speed SerDes circuit signals, the difficulty of heat dissipation from high-power active devices, and the integrity of large-scale circuit power supplies within the module, a high-reliability design was achieved through comprehensive simulation and optimization methods covering mechanical, electrical, and thermal aspects. Small-scale trial production and functional performance testing have also been completed. The product measures 39 mm×39 mm×6.49 mm and weighs 29 g. Compared to a system composed of discrete components, the volume and weight are reduced by over 80%. At ambient temperature(25°C) and high temperature(105°C), the DSP and FPGA functions within the microsystem module operate stably, memory read/write operations function normally, and the high-speed communication rate can reach 5 Gb/s. All functions and performance indicators meet the design expectations. The work presented in this manuscript can provide ideas and methods for the miniaturization, high integration, and high-reliability design of similar system-level packaging products.

引言
針對當前電子系統(tǒng)的核心關鍵元器件和計算機等部組件小型化、低成本和快速研制的迫切需求,在已有國產技術基礎上,如何快速提升電子系統(tǒng)的技術成熟度,大幅度降低電子產品體積、重量、成本,建立適用于通用化和批量化需求的元器件與部組件“短、平、快”研制流程,縮短研制和交付周期,是當前亟需解決的核心關鍵技術攻關課題。采用系統(tǒng)級封裝(System in Package,SiP)[1-3]技術是當前解決系統(tǒng)微小型化和有效提升產品可靠性的一條有效途徑,該技術更能滿足集成電路向更高集成度、更高性能、更高工作頻率發(fā)展的要求。目前國內也有不少單位和研究機構基于SiP技術進行了相關產品設計和可靠性研究工作[4-6]。
本文提出了一種基于全國產化裸芯級封裝的SiP小型化通用計算控制模塊研制方法,通過將四核DSP、FPGA、SDRAM和Flash等器件進行系統(tǒng)集成和封裝,使產品的構造趨向模塊化、集成化,實現(xiàn)接口靈活擴展、高速通信、程序存儲及數(shù)據(jù)運算等功能。該模塊具有體積小、功耗低、處理性能高、通用性強、使用靈活等特點。該模塊相比傳統(tǒng)的由DSP和FPGA等單芯片組成的系統(tǒng),可極大縮小系統(tǒng)占用面積和系統(tǒng)功耗,大幅降低產品成本,縮短研制周期,對電子系統(tǒng)的發(fā)展、提高產品競爭力具有巨大促進作用。
