style="text-indent:25px">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。東莞標準SMT貼片技術(shù)</p><p style="text-indent:25px">SMT貼片中IC如何焊接的大概方法：1、將PCB電路板做好清潔并且固定好。2、給IC引腳圖上一側(cè)較邊緣位置的焊盤上錫。3、用鑷子把SMT貼片IC放在PCB電路板上設(shè)計好的位置并且固定。用電烙鐵在預先上錫的焊盤上加熱，焊好該引腳。4、仔細檢查引腳位置是否正確，若存在位置不正確的情況則需要重新焊接PCBA貼片IC。5、在確認引腳位置正確之后將焊好的引腳對角線位置的引腳焊好，這樣可以避免在焊接其他引腳時IC發(fā)生移動引起PCBA貼片IC引腳錯位。6、這時候就可以焊接其他引腳了，這個過程不錯的是使用帶有放大鏡的臺燈，焊接時選用尖頭電烙鐵將IC的引線一個一個仔細焊好。7、用放大鏡檢查引腳焊接情況，是否存在虛焊橋接等情況。8、橋接處理方法：SMT貼片IC引腳密集導致焊接發(fā)生橋接，這種情況將焊錫熔化后吸走進行重新焊接即可。這個過程要小心仔細不能損壞到引腳。9、再次用放大鏡檢查焊點,確保焊點合格且無粘連短路現(xiàn)象。東莞標準SMT貼片技術(shù)</p><p
