高頻貼(tie)(tie)(tie)片電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)工作中的(de)(de)(de)異常(chang)(chang)噪聲需(xu)要(yao)定期檢(jian)查嗎？1.定期檢(jian)查產品質量(liang)：看看電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)流波(bo)形是(shi)(shi)怎樣的(de)(de)(de)，如果波(bo)形正常(chang)(chang)，那么屏蔽貼(tie)(tie)(tie)片電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)的(de)(de)(de)質量(liang)就會(hui)出現(xian)問題(ti)。如果波(bo)形不正常(chang)(chang)，那就可能(neng)是(shi)(shi)電(dian)(dian)(dian)(dian)路(lu)中的(de)(de)(de)一(yi)個問題(ti)，需(xu)要(yao)調試。2.檢(jian)查生產過(guo)程：檢(jian)查電(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)電(dian)(dian)(dian)(dian)流和電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)的(de)(de)(de)導(dao)線直徑(jing)是(shi)(shi)否符合要(yao)求(qiu)，檢(jian)查電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)繞組的(de)(de)(de)過(guo)程，如繞組是(shi)(shi)否發生松動等(deng)。高頻貼(tie)(tie)(tie)片電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)異常(chang)(chang)噪聲的(de)(de)(de)解(jie)決方法(fa)：1.噪音一(yi)般是(shi)(shi)不可能(neng)解(jie)決的(de)(de)(de)，但(dan)一(yi)旦在使用貼(tie)(tie)(tie)片電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)的(de)(de)(de)過(guo)程中出現(xian)異常(chang)(chang)噪音，只(zhi)有一(yi)個解(jie)決辦法(fa)就是(shi)(shi)更換它。2.對于未(wei)使用的(de)(de)(de)貼(tie)(tie)(tie)片電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)產品，可以通(tong)過(guo)浸泡在靜水(shui)中、用膠水(shui)進(jin)行強化、更堅(jian)固的(de)(de)(de)繞組、改(gai)變鐵芯(xin)、具有良好的(de)(de)(de)磁致伸縮效(xiao)應等(deng)方法(fa)，簡單而有效(xiao)地減少(shao)噪音的(de)(de)(de)影響(xiang)。工字電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)可用于自動插件(jian)機器(qi)。深(shen)圳NR磁膠電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)原理

繞(rao)組線(xian)(xian)圈(quan)(quan)電感(gan)，繞(rao)線(xian)(xian)注意事項：1.繞(rao)線(xian)(xian)線(xian)(xian)圈(quan)(quan)的(de)(de)抽頭(tou)(tou)要有明(ming)顯的(de)(de)標記，有抽頭(tou)(tou)的(de)(de)線(xian)(xian)圈(quan)(quan)也要有明(ming)顯的(de)(de)標記，便(bian)于(yu)安裝和維護。2.不同(tong)(tong)(tong)頻(pin)率(lv)特(te)性的(de)(de)線(xian)(xian)圈(quan)(quan)、不同(tong)(tong)(tong)材(cai)料(liao)(liao)的(de)(de)磁芯和不同(tong)(tong)(tong)工(gong)作頻(pin)率(lv)的(de)(de)線(xian)(xian)圈(quan)(quan)具(ju)有不同(tong)(tong)(tong)的(de)(de)特(te)性。工(gong)作在(zai)(zai)音頻(pin)段(duan)的(de)(de)繞(rao)組線(xian)(xian)圈(quan)(quan)電感(gan)通常采(cai)用(yong)(yong)硅(gui)鋼片(pian)(pian)或坡莫合金(jin)作為磁芯材(cai)料(liao)(liao)。鐵氧體作為低頻(pin)磁芯材(cai)料(liao)(liao)，其電感(gan)大，可(ke)高(gao)達幾(ji)(ji)衡(heng)至幾(ji)(ji)十衡(heng)。在(zai)(zai)幾(ji)(ji)十萬赫(he)茲到幾(ji)(ji)兆赫(he)的(de)(de)范圍內，如中(zhong)波(bo)廣(guang)播段(duan)的(de)(de)線(xian)(xian)圈(quan)(quan)，一般(ban)采(cai)用(yong)(yong)鐵氧體磁芯，多(duo)股絕緣(yuan)線(xian)(xian)繞(rao)制。當頻(pin)率(lv)高(gao)于(yu)幾(ji)(ji)兆赫(he)時，磁芯采(cai)用(yong)(yong)高(gao)頻(pin)鐵氧體，空(kong)心線(xian)(xian)圈(quan)(quan)也常用(yong)(yong)。在(zai)(zai)這種情況下，不宜采(cai)用(yong)(yong)多(duo)股絕緣(yuan)線(xian)(xian)，而應采(cai)用(yong)(yong)單股粗鍍銀(yin)線(xian)(xian)纏繞(rao)。當頻(pin)率(lv)高(gao)于(yu)100MHz時，不能(neng)使(shi)(shi)用(yong)(yong)鐵氧體磁芯，只能(neng)使(shi)(shi)用(yong)(yong)空(kong)心線(xian)(xian)圈(quan)(quan)；如果需要微調，可(ke)以使(shi)(shi)用(yong)(yong)鋼芯。高(gao)頻(pin)電路(lu)中(zhong)使(shi)(shi)用(yong)(yong)的(de)(de)扼流(liu)圈(quan)(quan)，除電感(gan)和額定電流(liu)外，分布電容不應過大。成都繞(rao)線(xian)(xian)電感(gan)好用(yong)(yong)嗎導(dao)致(zhi)貼(tie)片(pian)(pian)繞(rao)線(xian)(xian)電感(gan)焊接不良原(yuan)因：貼(tie)片(pian)(pian)繞(rao)線(xian)(xian)電感(gan)焊盤有毛刺。

在(zai)(zai)片式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器的應用(yong)(yong)中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器的基本參數(shu)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)，品質因數(shu)，固(gu)有(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)，穩定性，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)通(tong)過和使用(yong)(yong)頻(pin)率等(deng)。主要表現(xian)為(wei)(wei)對低頻(pin)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻很小，近(jin)似為(wei)(wei)零(ling)，對高頻(pin)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻很大(da)。頻(pin)率越高，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻越大(da)。通(tong)常(chang)亨(heng)利這個單元太大(da)了，常(chang)用(yong)(yong)單位是“毫享，mH”、“微享，uH”，在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中主要作用(yong)(yong)是濾波（整流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中濾除交流(liu)成份）、在(zai)(zai)有(you)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路常(chang)加(jia)一個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)阻止(zhi)高頻(pin)成份對外幅射、和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)一起組成高通(tong)或(huo)(huo)低通(tong)濾波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路等(deng)等(deng)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)是由線圈構成的，既(ji)有(you)空芯(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)，也有(you)鐵芯(xin)或(huo)(huo)磁芯(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)。加(jia)鐵芯(xin)或(huo)(huo)磁芯(xin)后的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)，會(hui)使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量增(zeng)大(da)很多(duo)。

實際上，電(dian)感(gan)(gan)(gan)器焊(han)(han)接(jie)在電(dian)感(gan)(gan)(gan)器生產(chan)中(zhong)并不(bu)(bu)(bu)是(shi)(shi)很重要(yao)，但它(ta)也(ye)是(shi)(shi)一個(ge)非常重要(yao)的步驟。我(wo)們有(you)必要(yao)做出(chu)合(he)理(li)的選擇，采取合(he)理(li)的方式來確保我(wo)們的電(dian)感(gan)(gan)(gan)性能更強(qiang)大。導致貼(tie)(tie)片(pian)繞線電(dian)感(gan)(gan)(gan)焊(han)(han)接(jie)不(bu)(bu)(bu)良(liang)原因(yin)：1、電(dian)感(gan)(gan)(gan)焊(han)(han)盤氧(yang)化或(huo)有(you)異物(wu)：貼(tie)(tie)片(pian)繞線電(dian)感(gan)(gan)(gan)焊(han)(han)接(jie)不(bu)(bu)(bu)良(liang)，電(dian)感(gan)(gan)(gan)焊(han)(han)盤有(you)氧(yang)化或(huo)有(you)異物(wu)是(shi)(shi)造成各種(zhong)電(dian)感(gan)(gan)(gan)焊(han)(han)錫不(bu)(bu)(bu)良(liang)的一種(zhong)常見(jian)問題，所以不(bu)(bu)(bu)只是(shi)(shi)貼(tie)(tie)片(pian)繞線電(dian)感(gan)(gan)(gan)，也(ye)是(shi)(shi)導致其他類(lei)型(xing)電(dian)感(gan)(gan)(gan)焊(han)(han)接(jie)不(bu)(bu)(bu)良(liang)的常見(jian)異常原因(yin)。2、貼(tie)(tie)片(pian)繞線電(dian)感(gan)(gan)(gan)焊(han)(han)盤有(you)毛刺：貼(tie)(tie)片(pian)繞線電(dian)感(gan)(gan)(gan)工藝(yi)中(zhong)有(you)一個(ge)切(qie)腳(jiao)作(zuo)業，在這個(ge)工藝(yi)中(zhong)，如果切(qie)刀(dao)保養不(bu)(bu)(bu)好，容易導致電(dian)感(gan)(gan)(gan)焊(han)(han)盤料片(pian)出(chu)現毛刺，這種(zhong)情況下也(ye)會造成電(dian)感(gan)(gan)(gan)貼(tie)(tie)附不(bu)(bu)(bu)平整(zheng)，從(cong)而(er)產(chan)生焊(han)(han)接(jie)不(bu)(bu)(bu)良(liang)。電(dian)感(gan)(gan)(gan)線圈(quan)的共同作(zuo)用是(shi)(shi)阻斷電(dian)流。

空心電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)線(xian)(xian)(xian)圈發熱(re)(re)怎么(me)解決呢(ni)？1、建議把磁(ci)心換大,這樣可(ke)減少匝數(shu),縮(suo)短線(xian)(xian)(xian)長(chang).正(zheng)激變換,紋波電(dian)(dian)流(liu)小(xiao),磁(ci)損小(xiao),主(zhu)要是電(dian)(dian)阻熱(re)(re)檢(jian)查濾波電(dian)(dian)容(rong)，還(huan)有(you)(you)電(dian)(dian)容(rong)失效 會造(zao)成電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)過熱(re)(re)變色。2、電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)是否(fou)接(jie)在(zai)整(zheng)流(liu)管后(hou)面？該電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)前(qian)端如(ru)有(you)(you)濾波電(dian)(dian)容(rong)請檢(jian)查是否(fou)開路(lu)。3、此電(dian)(dian)源(yuan)有(you)(you)兩個(ge)同樣的(de)(de)電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)，一(yi)個(ge)串在(zai)正(zheng)極(ji)，一(yi)個(ge)串在(zai)負極(ji)（沒有(you)(you)壞），貼(tie)片(pian)電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)前(qian)面直接(jie)的(de)(de)是可(ke)控的(de)(de)場管沒有(you)(you)其它電(dian)(dian)容(rong)，通過這兩個(ge)一(yi)正(zheng)一(yi)負串起來的(de)(de)電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)給一(yi)個(ge)線(xian)(xian)(xian)圈通電(dian)(dian)，并(bing)且由前(qian)端管子給的(de)(de)受控脈(mo)沖直電(dian)(dian)流(liu)。4、線(xian)(xian)(xian)經太(tai)細,這會導致電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)的(de)(de)電(dian)(dian)阻很(hen)大,在(zai)電(dian)(dian)流(liu)的(de)(de)有(you)(you)效值一(yi)定的(de)(de)情(qing)況下,電(dian)(dian)桿發熱(re)(re)就很(hen)正(zheng)常了(le)。加鐵芯或磁(ci)芯后(hou)的(de)(de)電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)，會使電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)量增大很(hen)多。江(jiang)蘇磁(ci)珠電(dian)(dian)感(gan)(gan)(gan)(gan)(gan)作用
