如何判斷FPC線路板的(de)優劣(lie)？

一：從外觀上分辨出(chu)電路板的好壞

一般情(qing)況下，FPC線路板(ban)外(wai)觀可通過三(san)個(ge)方面來(lai)分(fen)析判(pan)斷(duan);

1、大小和厚度(du)的標準規則。

線路板對標準電路板的厚度是不(bu)同的大小，客戶可以(yi)測量檢查根(gen)據自己產品的厚度及(ji)規格。

2、光和顏色。

外部電路板都有油墨(mo)(mo)覆蓋，線路板能起到絕(jue)緣(yuan)的作(zuo)用(yong)，如果板的顏色不亮，少點墨(mo)(mo)，保溫板本(ben)身是不好(hao)的。

3、焊縫外觀。

線路板由于零(ling)件較多，如果焊接不好(hao)，零(ling)件易(yi)脫落(luo)的線路板，嚴重(zhong)影響電路板的焊接質量，外觀好(hao)，仔細辨認，界面強(qiang)一(yi)點常(chang)重(zhong)要的。

第二：質(zhi)優(you)的(de)FPC線路(lu)板需要(yao)符合以下幾點(dian)要(yao)求(qiu)

1、要求(qiu)元件(jian)安裝上去(qu)以后(hou)電(dian)話機(ji)要好用(yong)，即電(dian)氣(qi)連接要符合要求(qiu);

2、線(xian)路(lu)(lu)(lu)的線(xian)寬、線(xian)厚(hou)、線(xian)距符合要求，以免線(xian)路(lu)(lu)(lu)發熱、斷路(lu)(lu)(lu)、和(he)短路(lu)(lu)(lu);

3、受高溫銅(tong)皮不容(rong)易脫落;

4、銅表面不容(rong)易(yi)氧化(hua)(hua)，影響安裝速度，氧化(hua)(hua)后用不久就(jiu)壞了(le);

5、沒(mei)有額外的(de)電磁輻射;

6、外形(xing)(xing)(xing)沒有變形(xing)(xing)(xing)，以免(mian)安裝(zhuang)(zhuang)后(hou)外殼變形(xing)(xing)(xing)，螺絲孔錯位。現(xian)在都是機械化安裝(zhuang)(zhuang)，線(xian)路板的(de)孔位和線(xian)路與設(she)計的(de)變形(xing)(xing)(xing)誤差應該在允許的(de)范圍之內;

7、而高(gao)溫、高(gao)濕及耐(nai)特殊也(ye)應該(gai)在考慮的范圍內(nei);

8、表面的力學性能要符合安裝要求。

中間層(ceng)，就(jiu)(jiu)是(shi)(shi)在PCB板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)頂(ding)層(ceng)和(he)(he)底層(ceng)之間的(de)(de)(de)(de)(de)(de)(de)層(ceng)，簡(jian)單(dan)地說多(duo)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)就(jiu)(jiu)是(shi)(shi)將多(duo)個單(dan)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)和(he)(he)雙(shuang)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)壓制(zhi)而(er)成(cheng)(cheng)，中間層(ceng)就(jiu)(jiu)是(shi)(shi)原先單(dan)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)和(he)(he)雙(shuang)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)頂(ding)層(ceng)或底層(ceng)。在PCB板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)制(zhi)作(zuo)過(guo)(guo)程中，首(shou)先需要在一(yi)塊(kuai)基底材料（一(yi)般采(cai)用合成(cheng)(cheng)樹(shu)脂材料）的(de)(de)(de)(de)(de)(de)(de)兩面敷上(shang)銅膜(mo)，然后通(tong)過(guo)(guo)光繪等(deng)工(gong)(gong)藝將圖紙中的(de)(de)(de)(de)(de)(de)(de)導線連接(jie)關系(xi)轉換到印(yin)(yin)制(zhi)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)材上(shang)（對(dui)圖紙中的(de)(de)(de)(de)(de)(de)(de)印(yin)(yin)制(zhi)導線、焊盤(pan)和(he)(he)過(guo)(guo)孔覆膜(mo)加(jia)以保(bao)(bao)護(hu)，防止這(zhe)些部分(fen)的(de)(de)(de)(de)(de)(de)(de)銅膜(mo)在接(jie)下來的(de)(de)(de)(de)(de)(de)(de)腐(fu)蝕工(gong)(gong)藝中被腐(fu)蝕），再(zai)通(tong)過(guo)(guo)化學(xue)腐(fu)蝕的(de)(de)(de)(de)(de)(de)(de)方(fang)式（以FeCl3或H2O2為主要成(cheng)(cheng)分(fen)的(de)(de)(de)(de)(de)(de)(de)腐(fu)蝕液）將沒有覆膜(mo)保(bao)(bao)護(hu)部分(fen)的(de)(de)(de)(de)(de)(de)(de)銅膜(mo)腐(fu)蝕掉，然后完(wan)(wan)成(cheng)(cheng)鉆孔，印(yin)(yin)制(zhi)絲(si)印(yin)(yin)層(ceng)等(deng)后期處理工(gong)(gong)作(zuo)，這(zhe)樣(yang)一(yi)塊(kuai)PCB板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)就(jiu)(jiu)基本制(zhi)作(zuo)完(wan)(wan)成(cheng)(cheng)了(le)。同(tong)理，多(duo)層(ceng)PCB板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)就(jiu)(jiu)是(shi)(shi)在多(duo)個板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)層(ceng)完(wan)(wan)成(cheng)(cheng)后再(zai)采(cai)取壓制(zhi)工(gong)(gong)藝將其壓制(zhi)成(cheng)(cheng)一(yi)塊(kuai)電(dian)路板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)，而(er)且為了(le)減少成(cheng)(cheng)本和(he)(he)過(guo)(guo)孔干擾，多(duo)層(ceng)PCB板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)往(wang)往(wang)并(bing)不比雙(shuang)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)和(he)(he)單(dan)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)厚(hou)多(duo)少，這(zhe)就(jiu)(jiu)使得(de)組成(cheng)(cheng)多(duo)層(ceng)PCB板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)層(ceng)相(xiang)對(dui)于普通(tong)的(de)(de)(de)(de)(de)(de)(de)雙(shuang)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)和(he)(he)單(dan)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)往(wang)往(wang)厚(hou)度更小，機械(xie)強度更低，導致對(dui)加(jia)工(gong)(gong)的(de)(de)(de)(de)(de)(de)(de)要求更高。所以多(duo)層(ceng)PCB板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)制(zhi)作(zuo)費(fei)用相(xiang)對(dui)于普通(tong)的(de)(de)(de)(de)(de)(de)(de)雙(shuang)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)和(he)(he)單(dan)層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)就(jiu)(jiu)要昂貴(gui)許(xu)多(duo)。靈敏的(de)(de)(de)(de)(de)(de)(de)低電(dian)平電(dian)路中，以消(xiao)除接(jie)地環(huan)路中可能(neng)產生的(de)(de)(de)(de)(de)(de)(de)干擾，對(dui)每電(dian)路都應(ying)有各自隔離和(he)(he)屏蔽好(hao)接(jie)地線。
