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.
Key words : electromechanical control;system level packaging;package on package;high integrate

引言

機(jī)電控制領(lǐng)域非常寬泛,包括傳統(tǒng)的AC/DC電機(jī)控制,以及現(xiàn)代的伺服電機(jī)控制、步進(jìn)電機(jī)控制等。應(yīng)用場(chǎng)景有工業(yè)機(jī)器人、數(shù)控機(jī)床、自動(dòng)化生產(chǎn)線等,其核心技術(shù)是各類電機(jī)的速度調(diào)節(jié)和精確定位控制。傳統(tǒng)的機(jī)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(duì)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(shí)現(xiàn)走線互聯(lián),再將需要的信號(hào)和電源進(jìn)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(huì)產(chǎn)生翹曲,故集成芯片數(shù)量有限。為此,本文設(shè)計(jì)了一種基于TSV和FanOUT技術(shù)的機(jī)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。
