style="text-indent:25px">清潔時不要將酒精酒在SMT貼片機的吸嘴標記上。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滑油。將少量硅酮潤滑油涂在吸墊的外表面上，然后再用干布擦去潤滑油，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，查看負壓是否大于0.08MPa（600mmHg）。SMT貼片機械潤滑：對以下部件每月進行一次潤滑。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、潤滑油孔、多槽軸；托盤供料器的球形螺釘、滑動組件、多槽軸。SMT貼片加工要求各裝配位號元器件的類型、型號和極性等特征標記要符合產(chǎn)品的裝配圖和BOM表要求。</p><div

1、用自動上板機，或人工把PCB輕輕放在傳送帶（或夾具）上，機器自動完成噴涂助焊劑、干燥、預(yù)熱、波峰焊、冷卻等操作。2、在波峰焊出口處接住PCB。3、按照行業(yè)標準《焊點質(zhì)量評定》SJ/T10666-1995或IPC-A-610E進行首件焊接質(zhì)量檢驗。根據(jù)首件焊接結(jié)果調(diào)整焊接參數(shù)，直到質(zhì)量符合要求后才能進行連續(xù)批量生產(chǎn)。PCBA首件檢驗我們之前就已經(jīng)反復(fù)強調(diào)過，其重要性不言而喻。為什么說在波峰焊后要進行首件檢測呢？其實PCBA的主要生產(chǎn)流程包括：錫膏印刷、SMT貼片、回流焊焊接、DIP插件、波峰焊焊接。如果沒有問題的話，經(jīng)過了波峰焊焊接的電路板就可以拿回去組裝成完成品了。那么如果我們對一個已經(jīng)走完了生產(chǎn)流程的產(chǎn)品不加檢驗就去生產(chǎn)，如果出現(xiàn)品質(zhì)異常，那么已經(jīng)組裝好的產(chǎn)品也要拆下來重新返修。所以除非是客戶明確表示不用做首件檢測的情況，其余情況下，PCBA加工廠一定要在波峰焊接完成之后進行首件檢測，經(jīng)過檢驗合格之后跟客戶確認，下一步在進行量產(chǎn)和批量生產(chǎn)才是一個可行的方案。天津貼片加工價格表</p><p
