style="text-indent:25px">從事SMT貼片行業(yè)以來(lái)很多的時(shí)候我們都會(huì)被客戶(hù)問(wèn)到，你們的貼片機(jī)怎么樣？是高速機(jī)還是什么機(jī)？是全自動(dòng)的還是半自動(dòng)的？你們的貼片機(jī)多少錢(qián)一臺(tái)？還有的客戶(hù)會(huì)問(wèn)，大概多少錢(qián)能給架起一條SMT貼片線呢？其實(shí)不只是客戶(hù)關(guān)心關(guān)注我們的貼片機(jī)，作為SMT貼片加工廠商，貼片機(jī)就是我們吃飯的飯碗，那么如何維護(hù)好SMT貼片機(jī)，就是我們必須要考慮的問(wèn)題。那么貼片機(jī)如何維護(hù)好呢？1.機(jī)械活動(dòng)模組部分。如果要是超負(fù)荷的去使用，那么就需要機(jī)器長(zhǎng)時(shí)間的不間斷運(yùn)行，首先各類(lèi)活動(dòng)模塊的部分，就會(huì)磨損（比如：絲桿、導(dǎo)軌、滑塊，傳動(dòng)皮帶，馬達(dá)聯(lián)軸器等），跟汽車(chē)的保養(yǎng)一樣，潤(rùn)滑油這部分的保養(yǎng)就必須及時(shí)到位。如果長(zhǎng)時(shí)間的干磨不只會(huì)降低機(jī)器在長(zhǎng)時(shí)間在超負(fù)荷狀態(tài)下的精度對(duì)品質(zhì)造成的問(wèn)題，同時(shí)也會(huì)加急機(jī)器使用壽命的衰減。2.電路管網(wǎng)及表面處理。只要有空氣的地方就避免不了會(huì)出現(xiàn)灰塵和積垢，如果積垢長(zhǎng)時(shí)間的堆積，會(huì)對(duì)電路的散熱造成致命的損害，溫度過(guò)熱會(huì)對(duì)電路的壽命產(chǎn)生非常大的影響。SMT貼片整個(gè)生產(chǎn)過(guò)程中用到的設(shè)備和工具都應(yīng)具有防靜電能力。</p><div
