style="text-indent:25px">在SMT貼片加工過程中要用到多種檢測設(shè)備，以在線或離線的形式工作，以達(dá)到產(chǎn)品的制造、檢驗(yàn)的要求。為了保證產(chǎn)品制造過程中的質(zhì)量，檢測設(shè)備的準(zhǔn)備非常重要。檢測設(shè)備：1.AOI的準(zhǔn)備內(nèi)容:檢查運(yùn)行狀態(tài)，工藝文件，檢測程序，SMT技術(shù)員設(shè)置工藝參數(shù)，光源，杭州smt電子貼片生產(chǎn)，運(yùn)行記錄等。2.ICT的準(zhǔn)備內(nèi)容:檢查運(yùn)行狀態(tài)、工藝文件，檢測程序，設(shè)置工藝參數(shù)，運(yùn)行記錄，針床夾具等。3.AM的準(zhǔn)備內(nèi)容:檢査運(yùn)行狀態(tài)，工藝文件，檢測程序，杭州smt電子貼片生產(chǎn)，杭州smt電子貼片生產(chǎn)，設(shè)置工藝參數(shù)，防輻射，運(yùn)行記錄等。SMT貼片有良好的潤濕性，焊接點(diǎn)的邊緣應(yīng)當(dāng)較薄。杭州smt電子貼片生產(chǎn)</p><div

style="text-indent:25px">SMT貼片再流焊設(shè)備的質(zhì)量：再流焊質(zhì)量與設(shè)各有著十分密切的關(guān)系。影響SMT貼片再流焊質(zhì)量的主要參數(shù)如下。 1、溫度控制精度應(yīng)達(dá)到0.1-0.2℃，溫度傳感器的靈敏度要滿足要求 2、溫度分布的均勻性，無鉛要求傳輸帶橫向溫差＜生2℃，否則很難保證整板的焊接質(zhì)量 3、加熱區(qū)長度。加熱區(qū)長度越長、加熱區(qū)數(shù)量越多，越容易調(diào)整和控制溫度曲線。 4、傳送帶運(yùn)行要平穩(wěn)，傳送帶振動(dòng)會(huì)造成移位、立碑、冷焊等焊接缺陷。 5、加熱效率會(huì)影響溫度曲線的調(diào)整和控制。加熱效率與設(shè)各結(jié)構(gòu)、空氣流動(dòng)設(shè)計(jì)等有關(guān) 6、是否配備氮?dú)獗Ｗo(hù)系統(tǒng)，氮?dú)獗Ｗo(hù)可以減少高溫氧化，提高焊點(diǎn)浸潤性 7、應(yīng)具備溫度曲線測試功能，如果設(shè)備無此配置，應(yīng)外購溫度曲線采集器。SMT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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">電子產(chǎn)品都是通過在PCB板上加上各種電容、電阻等電子元器件，從而實(shí)現(xiàn)不同使用功能的，而這些元件要能穩(wěn)固的裝在PCB上，就需要各種不同的SMT貼片加工工藝來進(jìn)行加工組裝。SMT貼片加工是一種將無引腳或短引線表面組裝元器件，簡稱SMC或SMD，中文稱片狀元器件，安裝在印制電路板的表面或其它基板的表面上，通過再流焊或浸焊等方法加以焊接組裝的電路裝連技術(shù)。SMT基本工藝構(gòu)成要素有：錫膏印刷--> 零件貼裝-->回流焊接-->AOI光學(xué)檢測--> 維修--> 分板。SMT貼片加工的優(yōu)點(diǎn)：實(shí)現(xiàn)了電子產(chǎn)品組裝的高密度、高可靠、小型化、低成本，以及生產(chǎn)的自動(dòng)化。</p><p style="text-indent:25px">SMT貼片膠的使用目的：①波峰焊中防止元器件脫落(波峰焊工藝)。在使用波峰焊時(shí)，為防止印制板通過焊料槽時(shí)元器件掉落，而將元器件固定在印制板上。②再流焊中防止另一面元器件脫落(雙面再流焊工藝)。雙面再流焊工藝中，為防止已焊好的那一面上大型器件因焊料受熱熔化而脫落，要使有SMT貼片膠。③防止元器件位移與立處(再流焊工藝、預(yù)涂敷工藝)。用于再流焊工藝和預(yù)涂敷工藝中防止貼裝時(shí)的位移和立片。④作標(biāo)記(波峰焊、再流焊、預(yù)涂敷)。此外，印制板和元器件批量改變時(shí)，用貼片膠作標(biāo)記。SMT生產(chǎn)工藝有兩條基本的工藝流程，即焊膏一回流焊工藝和貼片膠一波峰焊工藝。</p><div

style="text-indent:25px">SMT貼片膠的管理：由于SMT貼片紅膠受溫度影響用本身粘度，流動(dòng)性，潤濕等特性，所以SMT貼片紅膠要有一定的使用條件和規(guī)范的管理。1)紅膠要有特定流水編號(hào)，根據(jù)進(jìn)料數(shù)量、日期、種類來編號(hào)。2)紅膠要放在2～8℃的冰箱中保存，防止由于溫度變化，影響特性。3)紅膠回溫要求在室溫下回溫4小時(shí)，按先進(jìn)先出的順序使用。4)對于點(diǎn)膠作業(yè)，膠管紅膠要脫泡，對于一次性未用完的紅膠應(yīng)放回冰箱保存，舊膠與新膠不能混用。5)要準(zhǔn)確地填寫回溫記錄表，回溫人及回溫時(shí)間，使用者需確認(rèn)回溫完成后方可使用。通常，紅膠不可使用過期的。在SMT貼片加工中，隨著PCBA電路板的集成度越來越高，集成電路的內(nèi)絕緣層越來越薄。鄭州貼片smt加工</p><p
