如何正確選購(gou)LED軟光條

　　在您選購LED 軟光條的時候，不要只是關注價格，要從以下幾方面去綜合考核，才能買到性價比好的LED 軟光條。

　　1、LED軟光條采用的芯片：芯片有國產和臺灣芯片，還有進口芯片(包括美國芯片、日本芯片、德國芯(xin)片(pian)等)。芯(xin)片(pian)不同(tong)，價格差異(yi)很大。進口芯(xin)片(pian)價格比較(jiao)昂貴，在國(guo)內市場很少人用，那種主要是針對高端客戶。目前(qian)的中高端客戶一般選用的是臺灣(wan)芯片，性價比是**的。

　　2、LED軟光條封裝：分樹脂封裝和硅膠封裝。樹脂封裝的價格要便宜一些，因為散熱性能稍差，其他都(dou)是(shi)一樣。硅膠封(feng)裝的(de)散熱(re)性能好，因此價格要比樹脂封(feng)裝的(de)稍貴一點(dian)。

　　3、LED軟光條顏色的一致性：目前國內有很多封裝廠，大大小小加起來也有上千家，當然也就有實力的強弱之分(fen)。有很多(duo)小(xiao)的封裝廠由于(yu)沒有分(fen)光(guang)分(fen)色機，因此(ci)要么(me)不分(fen)光(guang)分(fen)色，要么(me)就是外發(fa)。這(zhe)樣對于(yu)品(pin)質就很(hen)難保證(zheng)。

　　4、LED軟光條焊接效果：LED軟光條的組裝分手工焊接和機器焊接兩種，手工焊接就是用烙鐵，采用原始(shi)的辦法進(jin)行焊接。這種作業(ye)方式(shi)出來(lai)的產品一(yi)是(shi)外(wai)觀難看(焊點大小不(bu)一(yi)致、助焊劑殘留(liu)多、焊點(dian)不(bu)光(guang)滑、LED 封裝被燙壞(huai)等)，二是靜(jing)電(dian)保護措(cuo)施不(bu)好，很多(duo)LED 芯片被擊(ji)穿，導致通(tong)電(dian)時(shi)出(chu)(chu)現微亮(liang)或者不(bu)亮(liang)的(de)現象。機(ji)器(qi)焊(han)(han)接就不(bu)一樣，機(ji)器(qi)焊(han)(han)接是用回流焊(han)(han)進(jin)行焊(han)(han)接，不(bu)僅焊(han)(han)接后的(de)產品(pin)外觀漂亮(liang)(焊(han)(han)點(dian)大(da)小(xiao)一致、焊(han)(han)點(dian)光(guang)滑、焊(han)(han)錫量呈規則的(de)圓弧狀、無助焊(han)(han)劑殘留、LED 封裝完(wan)好)，而且不(bu)會出(chu)(chu)現芯片被靜(jing)電(dian)燒壞(huai)的(de)現象。同時(shi)，LED 的(de)位置和方向都比(bi)較美觀。這個可以從外觀上直接看(kan)出(chu)(chu)來(lai)。

　　5、LED軟(ruan)光條 FPC材質：FPC 分壓(ya)(ya)延(yan)銅(tong)(tong)(tong)(tong)(tong)(tong)和敷銅(tong)(tong)(tong)(tong)(tong)(tong)兩種(zhong)，敷銅(tong)(tong)(tong)(tong)(tong)(tong)板比較便宜，壓(ya)(ya)延(yan)銅(tong)(tong)(tong)(tong)(tong)(tong)比較貴。電解(jie)銅(tong)(tong)(tong)(tong)(tong)(tong)顧名(ming)思義就是通(tong)過(guo)電解(jie)的(de)(de)方(fang)法使銅(tong)(tong)(tong)(tong)(tong)(tong)離子吸附在(zai)基材上而形成銅(tong)(tong)(tong)(tong)(tong)(tong)箔，所以(yi)它的(de)(de)特(te)點是：導電性強(qiang)，但(dan)耐彎(wan)折度(du)(du)相對(dui)較弱;壓(ya)(ya)延(yan)銅(tong)(tong)(tong)(tong)(tong)(tong)就是將高(gao)純(chun)度(du)(du)(>99.98%)的(de)(de)銅(tong)(tong)(tong)(tong)(tong)(tong)用碾壓(ya)(ya)法貼在(zai)FPC 上--因為FPC 與銅(tong)(tong)(tong)(tong)(tong)(tong)箔有極好的(de)(de)粘合性，銅(tong)(tong)(tong)(tong)(tong)(tong)箔的(de)(de)附著強(qiang)度(du)(du)和工作溫度(du)(du)較高(gao)，可以(yi)在(zai)260℃的(de)(de)熔錫中浸焊而無起泡。這個過(guo)程頗像搟餃子皮，*薄可以(yi)小于1mil(工業單位：密耳，即(ji)千分之一英寸，相當于0.0254mm)。壓(ya)(ya)延(yan)銅(tong)(tong)(tong)(tong)(tong)(tong)是通(tong)過(guo)擠(ji)壓(ya)(ya)的(de)(de)方(fang)法得到(dao)銅(tong)(tong)(tong)(tong)(tong)(tong)箔，它的(de)(de)特(te)點是：耐彎(wan)折度(du)(du)好，但(dan)導電性弱于電解(jie)銅(tong)(tong)(tong)(tong)(tong)(tong)，主要(yao)用于翻蓋手機里的(de)(de)攝像頭之類的(de)(de)。從外觀上看(kan)，電解(jie)銅(tong)(tong)(tong)(tong)(tong)(tong)發紅(hong)，壓(ya)(ya)延(yan)銅(tong)(tong)(tong)(tong)(tong)(tong)偏黃

　　6、FPC 有(you)無經(jing)過(guo)環(huan)保認(ren)證(zheng)、UL 認(ren)證(zheng)?LED 有(you)無**等。有(you)經(jing)過(guo)認(ren)證(zheng)和有(you)**的，價(jia)格比較(jiao)貴，沒有(you)的價(jia)格便宜。

　　7、LED的亮(liang)(liang)度：不同亮(liang)(liang)度的LED價(jia)格(ge)不同，普通(tong)亮(liang)(liang)度和高亮(liang)(liang)的 LED 價(jia)格(ge)相(xiang)差比較懸殊。因此，采購(gou)的時候一定(ding)要清楚的知道自己需(xu)要的是(shi)什么樣的亮(liang)(liang)度，這樣才(cai)能(neng)準(zhun)確(que)的定(ding)位自己的產品。一般選購(gou)如果(guo)明了這幾(ji)項的話，對于價(jia)格(ge)的把握會比較準(zhun)確(que)。不至于只(zhi)是(shi)為了殺價(jia)而殺價(jia)，能(neng)做到有的放矢。這樣才(cai)能(neng)選購(gou)您理想的LED 軟(ruan)光(guang)條。
