style="text-indent:25px">SMT貼片涂敷工藝及設(shè)備：SMT貼片進(jìn)行涂敷的主要目的是將膠水或焊膏精確地涂敷于PCB上，使貼片工序貼裝的元器件能夠粘在PCB焊盤(pán)上。按照涂數(shù)方式的不同表面涂數(shù)工藝可分為以下幾種。根據(jù)SMT貼片加工焊膏與貼片膠組成成分的不同，焊膏涂敷通常采用模板絲網(wǎng)印刷工藝、噴涂工藝、點(diǎn)涂工藝，貼片膠涂敷通常采用注射點(diǎn)涂工藝、針式轉(zhuǎn)移工藝、絲網(wǎng)模板印刷工藝，二者的優(yōu)先選擇順序也分別是模板絲網(wǎng)印工藝和注射點(diǎn)涂工藝。焊膏或貼片膠涂敷時(shí)，SMT加工廠大批量生產(chǎn)一般使用大型自動(dòng)化設(shè)備，諸如，印刷機(jī)、點(diǎn)膠機(jī)、點(diǎn)膏機(jī)等。小批量或手工涂敷時(shí)，通常采用臺(tái)式點(diǎn)膠或點(diǎn)膏機(jī)、臺(tái)式印劇機(jī)甚至手工涂敷。鎮(zhèn)江smt貼片有什么用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。</p><div

style="text-indent:25px">SMT貼片紅膠是一種聚稀化合物，主要成份為基料（即主體高份子材料）、填料、固化劑、其它助劑等。SMT貼片紅膠具有粘度流動(dòng)性，溫度特性，潤(rùn)濕特性等。根據(jù)紅膠的這個(gè)特性，故在生產(chǎn)中，利用紅膠的目的就是使零件牢固地粘貼于PCB表面，防止其掉落。因此貼片膠是屬于純消耗非必需的工藝過(guò)程產(chǎn)物，現(xiàn)在隨著PCA設(shè)計(jì)與工藝的不斷改進(jìn)，通孔回流焊、雙面回流焊都已實(shí)現(xiàn)，用到貼片膠的PCA貼裝工藝呈越來(lái)越少的趨勢(shì)。SMT貼片膠的儲(chǔ)存：在室溫下可儲(chǔ)存7天，在小于5℃時(shí)儲(chǔ)存大于個(gè)6月，在5～25℃可儲(chǔ)存大于30天。</p><p style="text-indent:25px">在SMT貼片加工的日常工作中，我們經(jīng)常會(huì)遇到一些做電力電子、電源、工業(yè)控制、充電樁的產(chǎn)品，上面大多數(shù)都是DIP插件物料，而且很多的物料因?yàn)楦N片物料的耐溫性和加工要求不一致，就需要用到手工焊接，特別是常見(jiàn)的翼形引腳元件比較常見(jiàn)。一般情況下如果是不能機(jī)貼的話，會(huì)選擇用人工手焊的形式把之后剩余的幾個(gè)料焊接上去。那么翼形引腳的手工焊接方法您了解多少呢？一、逐個(gè)焊點(diǎn)焊接：1、用鑷子夾持器件，對(duì)準(zhǔn)方向使引腳與PCB焊盤(pán)對(duì)齊，居中貼放在相應(yīng)的焊盤(pán)上。2、選用圓錐形或鑿子形烙鐵頭，焊牢器件斜對(duì)角1~2個(gè)引腳。3、從***條引腳開(kāi)始、順序逐個(gè)焊點(diǎn)焊接，同時(shí)加少許直徑0.5mm（或更細(xì)一些）的焊錫絲，將器件兩側(cè)或四周引腳全部焊牢。窄間距時(shí)，不容易控制焊錫絲的送入量，因此也可以涂助焊劑，然后用轉(zhuǎn)移法逐個(gè)焊點(diǎn)焊接。二、拖焊法：1、用鑷子夾持器件，對(duì)準(zhǔn)極性和方向，使引腳與焊盤(pán)對(duì)齊，居中貼放在相應(yīng)的焊盤(pán)上，用圓錐或鑿子形烙鐵頭先焊牢器件斜對(duì)角1~2個(gè)引腳。2、涂助焊劑。3、給烙鐵頭上錫。4、從***條引腳開(kāi)始、順序向下緩慢勻速拖拉烙鐵，將器件兩側(cè)全部焊牢。SMT貼片加工設(shè)備工藝流程：模板：(鋼網(wǎng))

1、SMT貼片技術(shù)員佩戴好檢驗(yàn)OK的靜電環(huán)，插件前檢查每個(gè)訂單的電子元件無(wú)錯(cuò)/混料、破損、變形、劃傷等不良現(xiàn)象 2、電路板的插件板需要提前把電子物料準(zhǔn)備好，注意電容極性方向須正確無(wú)誤 3、SMT印刷作業(yè)完畢后進(jìn)行無(wú)漏插、反插、錯(cuò)位等不良產(chǎn)品的檢查，將良好的上錫完成品流入下一工序。 4、SMT貼片組裝作業(yè)前請(qǐng)配戴靜電環(huán),金屬片緊貼手腕皮膚并保持接地良好,雙手交替作業(yè)。 5、?USB/IF座子/屏蔽罩/高頻頭/網(wǎng)口端子等金屬元件,插件時(shí)須戴手指套作業(yè)。 6、所插元器件位置、方向須正確無(wú)誤,元件平貼板面,架高元件必須插到K腳位置。 7、如有發(fā)現(xiàn)物料與SOP以及BOM表上規(guī)格不一致時(shí),須及時(shí)向班/組長(zhǎng)報(bào)告。 8、物料需輕拿輕放不可將經(jīng)過(guò)SMT前期工序的PCB板掉落而導(dǎo)致元件受損,晶振掉落不可使用。 9、上下班前請(qǐng)將工作臺(tái)面整理干凈,并保持清潔。 10、嚴(yán)格遵守作業(yè)區(qū)操作規(guī)則，首件檢測(cè)區(qū)、待檢區(qū)、不良區(qū)、維修區(qū)、少料區(qū)的產(chǎn)品嚴(yán)禁私自隨意擺放，上下班交接要注明未完工序。SMT貼片加工中出現(xiàn)的連錫，漏焊等各種工藝問(wèn)題。鎮(zhèn)江smt貼片有什么用</p><p style="text-indent:25px">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)。江蘇貼片加工工廠</p><p 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(mǎn)足要求 2、溫度分布的均勻性，無(wú)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(zhǎng)度。加熱區(qū)長(zhǎng)度越長(zhǎng)、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(rùn)性 7、應(yīng)具備溫度曲線測(cè)試功能，如果設(shè)備無(wú)此配置，應(yīng)外購(gòu)溫度曲線采集器。江蘇貼片加工工廠</p><p style="text-indent:25px">中山市浩明電子科技有限公司是一家SMT (貼片)+COB(邦定) 來(lái)料代加工，擁有8條高精密全自動(dòng)生產(chǎn)線，可貼裝 0402 、 0201 、SOT 、SOP
