style="text-indent:25px">SMT貼片機(jī)的維護(hù)和保養(yǎng)是整個(gè)PCBA制造工序中的重要事情，特別是機(jī)械和電子儀器的保養(yǎng)。所有機(jī)械部分的維護(hù)包括貼裝頭、吸嘴、空氣壓力、潤(rùn)滑等的的維護(hù)。 1.貼裝頭：空氣通道一為了保證機(jī)器的精確性和安裝速度，浙江smt貼片專業(yè)加工，要求定期清潔空氣通道（從空氣過(guò)濾組件到吸嘴托進(jìn)行吹氣）?？諝膺^(guò)濾器一一每星期將空氣過(guò)濾器從空氣過(guò)濾組件中拿出一次，査看其污染情況。如果被灰塵堵塞，予以更換。 2.吸嘴：如果吸嘴有污物，如焊料，堵在吸嘴里，吸氣就不會(huì)有力。如果在吸嘴的底面有污物，會(huì)造成漏氣，同時(shí)造成進(jìn)行圖像處理時(shí)，浙江smt貼片專業(yè)加工，系統(tǒng)不能識(shí)別較小的元件。用酒精清潔吸嘴，用吹風(fēng)機(jī)吹去灰塵（每周至少一次），浙江smt貼片專業(yè)加工。檢查橡膠吸墊是否有裂縫和污染。SMT貼片降低成本達(dá)30%~50%。浙江smt貼片專業(yè)加工</p><div

style="text-indent:25px">清潔時(shí)不要將酒精酒在SMT貼片機(jī)的吸嘴標(biāo)記上。如果不小心灑上了，要立即將其擦去。清潔吸嘴后，一定要再涂上硅酮潤(rùn)滑油。將少量硅酮潤(rùn)滑油涂在吸墊的外表面上，然后再用干布擦去潤(rùn)滑油，可防止橡膠吸墊變質(zhì)。檢査空氣壓力，這一步主要檢查真空排出管的性能。首先打開真空閥門，然后用手指堵住吸嘴頂部，查看負(fù)壓是否大于0.08MPa（600mmHg）。SMT貼片機(jī)械潤(rùn)滑：對(duì)以下部件每月進(jìn)行一次潤(rùn)滑。X軸球形螺釘，X軸引導(dǎo)器；y軸引導(dǎo)器、引導(dǎo)軸、球形螺釘、調(diào)節(jié)螺釘；傳輸導(dǎo)軌引導(dǎo)軸；貼裝頭球形螺桿、線性通路、潤(rùn)滑油孔、多槽軸；托盤供料器的球形螺釘、滑動(dòng)組件、多槽軸。杭州smt貼片加工電子SMT貼片加工中焊膏中焊劑含量太高，在回流焊過(guò)程中過(guò)多的焊劑的流動(dòng)導(dǎo)致了元器件的移位。</p><div

style="text-indent:25px">SMT貼片加工焊接后的清洗是指利用物理作用、化學(xué)反應(yīng)的方法去除SMT再流焊、波峰焊和手工焊后殘留在表面組裝板表面的助焊劑殘留物及貼片加工組裝工藝過(guò)程中造成的污染物、雜質(zhì)的工序污染物對(duì)表面組裝板的危害 1、焊劑和焊音中添加的活化劑帶有少量西化物、酸或鹽，焊接后形成極性殘留物履蓋在焊點(diǎn)表面。當(dāng)電子產(chǎn)品加電時(shí)，極性殘留物的離子就會(huì)朝極性相反的導(dǎo)體遷移，嚴(yán)重時(shí)會(huì)引起短路。 2、目前常用焊劑中的鹵化物、氯化物具有很強(qiáng)的活性和吸濕性，在湘濕的環(huán)境中對(duì)基板和焊點(diǎn)產(chǎn)生腐蝕作用，使基板的表面絕緣電阻下降并產(chǎn)生電遷移，嚴(yán)重時(shí)會(huì)導(dǎo)電，引起短路或斷路。</p><p style="text-indent:25px">SMT的特點(diǎn)：1、組裝密度高、電子產(chǎn)品體積小、重量輕，貼片元件的體積和重量只有傳統(tǒng)插裝元件的1/10左右，一般采用SMT之后，電子產(chǎn)品體積縮40%~60%，重量減輕60%~80%。2、可靠性高、抗振能力強(qiáng)。焊點(diǎn)缺陷率低。3、高頻特性好。減少了電磁和射頻干擾。4、易于實(shí)現(xiàn)自動(dòng)化，提高生產(chǎn)效率。降低成本達(dá)30%~50%。節(jié)省材料、能源、設(shè)備、人力、時(shí)間等。為什么要用表面貼裝技術(shù)(SMT)？ 1、電子產(chǎn)品追求小型化，以前使用的穿孔插件元件已無(wú)法縮小，電子產(chǎn)品功能更完整，所采用的集成電路(IC)已無(wú)穿孔元件，特別是大規(guī)模、高集成IC，不得不采用表面貼片元件產(chǎn)品批量化，生產(chǎn)自動(dòng)化，廠方要以低成本高產(chǎn)量，出產(chǎn)較好的產(chǎn)品以迎合顧客需求及加強(qiáng)市場(chǎng)競(jìng)爭(zhēng)力。2、電子元件的發(fā)展，集成電路(IC)的開發(fā)，半導(dǎo)體材料的多元應(yīng)用，電子科技**勢(shì)在必行，追逐國(guó)際潮流。貼裝所用設(shè)備為貼片機(jī)，位于SMT生產(chǎn)線中絲印機(jī)的后面。</p><div

style="text-indent:25px">SMT貼片加工中施加焊膏的工藝要求：1、施加的焊膏量均勻，一致性好。焊膏圖形要消晰，相鄰的圖形之間盡量不要粘連。焊膏圖形與焊盤圖形要一致，盡量不要錯(cuò)位。2、在一般情況下，焊盤上單位面積的焊膏量應(yīng)為0.8mg/mm3左右:對(duì)卒間距元器件，應(yīng)為0.5mgmm2左右。3、印刷在基板上的焊膏，與希望重量值相比，可允許有一定的偏差，至于焊膏覆蓋每個(gè)焊盤的面積，應(yīng)在75％以上。采用免清洗技術(shù)時(shí)，要求焊膏全部位于焊盤上，無(wú)鉛要求焊膏完全覆蓋焊盤。4、焊膏印刷后，應(yīng)無(wú)嚴(yán)重塌落，邊像整齊，錯(cuò)位不大于02mm對(duì)容間距元器件焊盤，錯(cuò)位不大于O0lm?；灞砻娌辉试S被焊膏污染。采用免清洗技術(shù)時(shí)，可通過(guò)縮小模板開口尺寸的方法，使焊膏全部位于焊盤上。加工SMT貼片過(guò)程中就需要了解元器件移位的原因，并針對(duì)性進(jìn)行解決。杭州smt貼片加工批發(fā)</p><p
