style="text-indent:25px">電子元器件自主可控是指在研發(fā)、生產(chǎn)和保證等環(huán)節(jié)，主要依靠國內(nèi)科研生產(chǎn)力量，在預(yù)期和操控范圍內(nèi)，滿足信息系統(tǒng)建設(shè)和信息化發(fā)展需要的能力。電子元器件關(guān)鍵技術(shù)及應(yīng)用，對電子產(chǎn)品和信息系統(tǒng)的功能性能影響至關(guān)重要，涉及到工藝、合物半導(dǎo)體、微納系統(tǒng)芯片集成、器件驗證、可靠性等。回顧過去一年國內(nèi)方案設(shè)計，電路板加工，PCBA OEM，SMT貼片產(chǎn)業(yè)運行情況，上半年市場低迷、部分外資企業(yè)產(chǎn)線轉(zhuǎn)移、中小企業(yè)經(jīng)營困難，開工不足等都是顯而易見的消極影響。但隨著方案設(shè)計，電路板加工，PCBA OEM，SMT貼片產(chǎn)業(yè)受到相關(guān)部門高度重視、下游企業(yè)與元器件產(chǎn)業(yè)的黏性增強、下游 5G 產(chǎn)業(yè)發(fā)展前景明朗等利好因素的驅(qū)使下，我國電子元器件行業(yè)下半年形勢逐漸好轉(zhuǎn)。根據(jù)近幾年的數(shù)據(jù)顯示，中國已然成為世界極大的電子元器件市場，每年的進口額高達2300多億美元，超過石油進口金額。但是**根本的痛點仍然沒有得到解決——眾多的有限責(zé)任公司企業(yè)，資歷不深缺少金錢，缺乏人才，渠道和供應(yīng)鏈也是缺少，而其中困惱還是忠實用戶的數(shù)量。服務(wù)包括電信服務(wù)、互聯(lián)網(wǎng)服務(wù)、信息接入軟件應(yīng)用等。信息服務(wù)的建設(shè)是各類信息產(chǎn)品應(yīng)用的基礎(chǔ),加大網(wǎng)絡(luò)提速降費力度和加快推進5G技術(shù)商用有利于推動加工產(chǎn)品創(chuàng)新和產(chǎn)業(yè)化升級。四川軟硬PCBA電路板公司</p><p
