href='http://www.joysunique.com/' target='_blank' class='key_tag'><font color=#2086ee><strong>防爆LED燈</strong></font></a>的出產門檻很低，所以很多人都開始做它。但是有經驗的人還是有方法辨認出正規廠家出產的LED燈和山寨版(也就是在出租屋里完全用手藝制作的產品)?，F在，防爆LED燈廠家就教你如何用肉眼來區分LED燈的質量。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">1、看包裝</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">一般的防爆LED燈帶都是選用防靜電盤式包裝，一般是5米一卷或10米一卷，外用防靜電防潮包裝袋密封。而且山寨版LED燈帶由于節省了本錢，挑選了材料板，便不再使用防靜電防潮的包裝袋，仔細看盤片就可以看出消除標簽外觀留下的痕跡和劃痕。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">2、看標志</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">一般防爆LED燈都會用帶有標簽的郵袋和卷筒來代替印刷標簽。標簽仿冒印刷，規范和參數不一致。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">3、看附件</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">為了節省資金，正規LED燈帶將附加使用說明和燈帶規范手冊，并將其配置為LED燈帶接頭或；而劣質的LED燈帶包裝將不附加。</span></p><p><br/></p><p style="text-align:center"><img src="http://www.joysunique.com/data/images/product/thumb_20180205141054_915.jpg" alt="防爆LED燈用肉眼識別好壞" width="484" height="364" border="0" vspace="0" title="防爆LED燈用肉眼識別好壞" style="width: 484px; height: 364px;"/></p><p><br/></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">4、看焊點</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">常規防爆LED燈選用SMT貼片工藝出產的防爆LED燈帶，選用錫膏回流焊工藝。所以防爆LED燈的焊點相對比較潤滑，焊接點數較少。焊接腳部選用多點包扎，焊接時會呈現不同程度的錫尖，這是典型的工藝焊接現象。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">5、看FPC與銅箔的覆銅片為凸面</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">從焊接片與FPC之間的銜接處可見。接近柔性線路板的壓延銅片可以恣意曲折而不掉落。鍍銅板材曲折過大，簡單產生焊點掉落，溫度過高維修也會形成焊點掉落。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">6、看防爆LED燈外外表清潔</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">如果選用SMT工藝出產的LED燈帶，其外觀干凈，無雜質，無污漬。但如果選用山寨手藝焊接工藝出產的防爆LED燈，不管其外觀多么干凈，都會留下污跡和清洗痕跡，FPC外觀乃至還會呈現焊劑和錫渣。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑,
