摘要: 机电控制系统包含多款芯片,其小型化、轻量化的需求日益迫切,系统级封装(System in Package)技术作为一种先进封装手段能够将多款不同类型的芯片集成于更小的空间中。基于系统级封装技术,并结合TSV与FanOUT技术设计了一款机电控制SiP电路,该电路包括顶层DSP信号控制单元和底层FPGA信号处理单元,两者通过PoP(Package on Package)形式堆叠构成SiP电路,相比于常规分立器件所搭建的机电控制系统,该SiP体积缩小70%以上,重量减轻80%以上。针对该款SiP电路设计了相应的测试系统,且对内部的ADC及DAC等芯片提出了一种回环测试的方法,能够提高测试效率。测试结果表明,该电路满足设计要求,在机电控制领域具有一定的应用前景。

Abstract: Electromechanical control system contains many kinds of chips, and its miniaturization and lightweight demand is increasingly urgent. As an advanced packaging method, system level packaging (System in Package)technology can integrate many different types of chips in a smaller space. In this paper, a SiP circuit of electromechanical control is designed based on system-level packaging technology, combined with TSV and FanOUT technology. The circuit includes the DSP signal control unit and the bottom FPGA signal processing unit, which are stacked in the form of PoP to form a SiP circuit. Compared with the electromechanical control system built by conventional discrete devices, the SiP volume is reduced by more than 70% and the weight is reduced by more than 80%. A test system is designed for SiP circuit, and a loopback test method is proposed for ADC and DAC chips, which can improve the test efficiency. The results show that the circuit meets the design requirements and has a certain application prospect in the field of electromechanical control.

引言
機電控制領域非常寬泛,包括傳統(tǒng)的AC/DC電機控制,以及現(xiàn)代的伺服電機控制、步進電機控制等。應用場景有工業(yè)機器人、數(shù)控機床、自動化生產(chǎn)線等,其核心技術(shù)是各類電機的速度調(diào)節(jié)和精確定位控制。傳統(tǒng)的機電控制系統(tǒng)一般是將DSP、FPGA、ADC、DAC和EEPROM等分立的元器件安裝在PCB上,這種形式的控制系統(tǒng)體積較大,在對空間有要求的情況下存在一定限制。
隨著集成電路封裝技術(shù)發(fā)展,SiP采用多芯片單封裝可以大幅度降低電路占用面積,提高系統(tǒng)可靠性,并降低成本[1-4]。常規(guī)的SiP方案一般采用基板形式,將不同芯片平鋪在塑封或陶瓷基板上,在基板上實現(xiàn)走線互聯(lián),再將需要的信號和電源進行扇出[5-12]。受基板加工工藝限制和封裝工藝限制,基板尺寸過大會產(chǎn)生翹曲,故集成芯片數(shù)量有限。為此,本文設計了一種基于TSV和FanOUT技術(shù)的機電控制SiP電路,采用上下兩層堆疊的方式,在同等面積上可集成2倍數(shù)量的芯片,能夠有效地解決上述問題。
