style="text-indent:25px">一般來說smt貼片機都會存在拋料問題，而拋料會產(chǎn)生缺件不良，其實拋料問題產(chǎn)生的主要原因一般是吸取不良和識別不良。1、吸取不良，主要原因是NOZZLE未能吸起材料，這種情況發(fā)生的原因可能是NOZZLE堵塞，缺損，F(xiàn)EEDER不良等原因造成的。在發(fā)生吸取不良時，應(yīng)該檢查吸嘴有沒有被堵塞或者表面是不是不平，這個問題可以通過更換吸嘴來解決。檢查FEEDER的進料位置是否正確，如果不正確可以通過微調(diào)整，使元件在吸取的中心點上來解決問題。檢查程序中設(shè)定的元件厚度是否正確，如果設(shè)定錯誤的話會導(dǎo)致機器無法識別從而造成無法吸取的情況。</p><p style="text-indent:25px">smt貼片：印刷：其作用是將焊膏或貼片膠漏印到PCB的焊盤上，為元器件的焊接做準備。所用設(shè)備為印刷機（錫膏印刷機），位于SMT生產(chǎn)線的前端。點膠：因現(xiàn)在所用的電路板大多是雙面貼片，為防止二次回爐時投入面的元件因錫膏再次熔化而脫落，故在投入面加裝點膠機，它是將膠水滴到PCB的固定位置上，其主要作用是將元器件固定到PCB板上。所用設(shè)備為點膠機，位于SMT生產(chǎn)線的前端或檢測設(shè)備的后面。有時由于客戶要求產(chǎn)出面也需要點膠，而現(xiàn)在很多小工廠都不用點膠機，若投入面元件較大時用人工點膠。SMT表面組裝技術(shù)也愈加成熟，設(shè)備和功能也在不斷完善，SMT貼片加工技術(shù)已經(jīng)逐漸取代傳統(tǒng)插裝技術(shù)。</p><div

style="text-indent:25px">smt貼片要降低成本，減少費用：(1)印制板使用面積減小，面積為通孔技術(shù)的1/12，若采用CSP安裝則其面積還要大幅度下降；(2)減少印制板的鉆孔數(shù)，節(jié)省返工費用；(3)由于頻率特性的提高，電路調(diào)試成本降低；(4)由于片式元器件體積小、重量輕，降低了包裝、運輸和儲存成本；SMT芯片加工工藝可節(jié)省材料、能源、設(shè)備、人力、時間等。成本可降低高達30％和50％。要實現(xiàn)穿孔安裝印制板的完全自動化，必須擴大40%原印制板面積，使自動插件的插裝頭可以插入元件，否則就沒有足夠的間隙，零件就會損壞。smt貼片加工的優(yōu)點:組裝密度高、電子產(chǎn)品體積小、重量輕。福建樣片SMT貼片售價</p><p style="text-indent:25px">smt貼片表面安裝元器件在功能上和插裝元器件沒有差別，其不同之處在于元器件的封裝。福建樣片SMT貼片售價</p><p style="text-indent:25px">SMT貼片加工價錢計算目前幾乎處于通明階段，幾錢一個點的算法很復(fù)雜。不過首先，需求明白“點”的概念，不同的公司采用的算法不同，但針對一塊PCB板來講，初的SMT貼片加工費用總價是一樣的。 SMT貼片加工的次要目的是將貼片元器件貼裝到PCB的焊盤上，有的公司將一個焊盤計算為一個點，但也有將兩個焊點（例如一個0201的貼片電阻）計作一個點的情況。以焊盤計算為一個點為例。只需求計算PCB板上一切的焊盤數(shù)即可，但是遇到一些特殊的元器件，比如電感、大的電容、IC等。福建樣片SMT貼片售價</p><p
