在使用之前，先將被粘接的元件表面清潔干凈，除掉表面的油污和其它雜質(zhì)（可用揮發(fā) 性有機(jī)溶劑，如：乙醇，**）。將錫膏涂覆于需粘接的焊點(diǎn)上，再將元件精細(xì)放置在焊點(diǎn)上，放置回流焊中高溫焊接。 </p> <p> 將涂覆好的元器件通過(guò)傳送帶送到回流焊中工作4-7分鐘，即可焊接且有導(dǎo)電作用； </p> <p> 開(kāi)啟后未用完再密封好，低溫存放，防止產(chǎn)品吸潮影響質(zhì)量； </p> <p> 由于錫膏的高粘度特性和針筒包裝形式，以及不同客戶(hù)的設(shè)備，使用方式等不同，針筒內(nèi) 有1-2g殘留錫膏，屬于正常現(xiàn)象； </p> <p> 04、錫膏的包裝、貯存及運(yùn)輸 </p> <p> <br /> </p> <p> 本品在-5℃-10℃下低溫貯存，產(chǎn)品有效貯存期6個(gè)月，超期復(fù)驗(yàn)，若符合標(biāo)準(zhǔn)，仍可使用； </p> <p> 包裝：瓶裝和針筒包裝。 </p> <p> 瓶裝：多用于500g的白色罐子。 </p> <p> 針筒：本品于5CC、10CC、30CC、55CC 透明針筒，6盎司、12盎司白色針筒包裝，東莞使用點(diǎn)膠針，可根據(jù)用戶(hù) 需求協(xié)商指定包裝； </p> <p> 針頭：目前主要用TT針頭（JD514，東莞使用點(diǎn)膠針，東莞使用點(diǎn)膠針,516）或塑座不銹鋼針頭或全不銹鋼針頭（18-25G針頭）； </p> <p> 本品按非危險(xiǎn)品貯存和運(yùn)輸。 </p> <p>

點(diǎn)膠機(jī)如何配置點(diǎn)膠針筒，隨著點(diǎn)膠行業(yè)迅速發(fā)展，點(diǎn)膠機(jī)種類(lèi)不斷增多，在點(diǎn)膠機(jī)使用中點(diǎn)膠針筒作為點(diǎn)膠配件，在膠過(guò)程中發(fā)揮著重要作用，那么怎樣選取一款適合的點(diǎn)膠針筒呢？目前點(diǎn)膠機(jī)常規(guī)用的塑料點(diǎn)膠針頭的尺寸分別有30cc、55cc、100cc、200cc不等。確定好塑料點(diǎn)膠針筒尺寸之后，然后選擇點(diǎn)膠控制器和適配器，點(diǎn)膠控制器主要作用為提供氣壓和回吸，可防止膠水漏滴和進(jìn)行點(diǎn)膠。適配器作用提供氣壓輸送管道和結(jié)合點(diǎn)膠針筒。把膠水放置在塑料點(diǎn)膠針筒內(nèi)之后，安裝上點(diǎn)膠適配器，打開(kāi)點(diǎn)膠適配器的回吸功能，防止膠水滴漏，然后就是使用點(diǎn)膠機(jī)進(jìn)行壓力桶耳機(jī)填充膠水了。 </p> <p> <br /> </p> <p> 另外選擇點(diǎn)膠針筒還需要考慮到膠水的性質(zhì)、膠水的粘稠度問(wèn)題以及膠水的化學(xué)性能問(wèn)題。例如瞬間膠：對(duì)水性使用安全式活塞和Teflon 內(nèi)襯金屬點(diǎn)膠針筒，對(duì)粘度較強(qiáng)的瞬間膠，可以使用錐形斜式點(diǎn)膠針頭，若需撓性則使用PP 點(diǎn)膠針頭。UV膠：使用琥珀色點(diǎn)膠針筒，白色活塞及斜式點(diǎn)膠針頭（可遮紫外線(xiàn)）若使用其他種類(lèi)點(diǎn)膠針頭。根據(jù)不同種類(lèi)的膠水選擇不同種類(lèi)的點(diǎn)膠針筒才能使點(diǎn)膠更加的高效和確保點(diǎn)膠的質(zhì)量。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> </p> <p> <br /> </p> </p> <p> <br /> 珠海點(diǎn)膠針客戶(hù)至上按照膠水的特殊性質(zhì)，粘稠度、以及化學(xué)性質(zhì)來(lái)進(jìn)行選取。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

對(duì)于點(diǎn)膠針筒所使用的膠水的固化，一般生產(chǎn)廠(chǎng)家已給出溫度曲線(xiàn)。在實(shí)際應(yīng)盡可能采用較高溫度來(lái)固化，使膠水固化后有足夠強(qiáng)度。 </p> <p> 與工作面距離 </p> <p> 不同的點(diǎn)膠機(jī)采用不同的點(diǎn)膠針筒，有些點(diǎn)膠針筒有一定的止動(dòng)度。每次工作開(kāi)始之前應(yīng)做點(diǎn)膠針筒與工作面距離的校準(zhǔn)，即Z軸高度校準(zhǔn)。 </p> <p> 氣泡 </p> <p> 膠水一定不能有氣泡。一個(gè)小小氣泡就會(huì)造成許多產(chǎn)品沒(méi)有膠水；每次中途更換膠管時(shí)應(yīng)排空連接處的空氣，防止出現(xiàn)空打現(xiàn)象。 </p> <p> 點(diǎn)膠壓力 </p> <p> 點(diǎn)膠設(shè)備給針管（膠）提供一定壓力以保證膠水供應(yīng)，壓力大小決定供膠量和膠水流出速度。壓力太大易造成膠水溢出、膠量過(guò)多；壓力太小則會(huì)出現(xiàn)點(diǎn)膠斷續(xù)現(xiàn)象和漏點(diǎn)，從而導(dǎo)致產(chǎn)品缺陷。應(yīng)根據(jù)膠水性質(zhì)、工作環(huán)境溫度來(lái)選擇壓力。環(huán)境溫度高會(huì)使膠水粘度變小、流動(dòng)性變好，這時(shí)需調(diào)低壓力值，反之亦然。 </p> <p> 膠水的粘度 </p> <p> 膠的粘度直接影響點(diǎn)膠針筒的質(zhì)量。粘度大，則膠點(diǎn)會(huì)變小，甚至拉絲；粘度小，膠點(diǎn)會(huì)變大，進(jìn)而可能滲染產(chǎn)品。點(diǎn)膠過(guò)程中，應(yīng)對(duì)不同粘度的膠水，選取合理的壓力和點(diǎn)膠速度 [1] 。 </p> <p>
