線路(lu)(lu)板做為一種(zhong)高科(ke)技的(de)產品，在電子產品中起著(zhu)重要(yao)的(de)作(zuo)用，那么線路(lu)(lu)板都(dou)是有(you)什么作(zuo)用呢?在了解線路(lu)(lu)板作(zuo)用的(de)時候(hou)，我們需要(yao)了解下線路(lu)(lu)板的(de)一些基本(ben)的(de)概念、主要(yao)結構(gou)等(deng)相關的(de)知識。

　　線路板定義：

　　電(dian)(dian)路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)名稱有：線路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，PCB板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，鋁基(ji)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，高頻板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，厚銅板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，阻抗板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，PCB，超(chao)薄(bo)線路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，超(chao)薄(bo)電(dian)(dian)路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，印刷(銅刻(ke)蝕技術)電(dian)(dian)路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)等(deng)。電(dian)(dian)路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)使電(dian)(dian)路(lu)迷你化、直(zhi)觀(guan)化，對于固定電(dian)(dian)路(lu)的(de)批量生產(chan)和(he)優化用電(dian)(dian)器布(bu)局起重(zhong)要作用。電(dian)(dian)路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)可稱為印刷線路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)或(huo)印刷電(dian)(dian)路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，英(ying)文名稱為(Printed Circuit Board)PCB、(Flexible Printed Circuit board)FPC線路(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban).

　　線路板結構：

　　印刷電路板主要由焊盤、過孔、安裝孔、導線、元器件、填充、等組(zu)成，其主要功能如下：

　　焊盤：用(yong)于焊接(jie)元器件引腳的金屬(shu)孔。

　　過(guo)孔(kong)：用于連接各(ge)層之間元器(qi)件引腳(jiao)的(de)金屬(shu)孔(kong)。

　　安裝孔：用(yong)于固定印刷電路板。

　　導線：用于連(lian)接元器件(jian)引腳的電氣網(wang)絡銅膜。

　　填充(chong)：用于(yu)地線網絡的敷銅，可以有效的減(jian)小阻抗。

　　線路板作用：

　　線(xian)路板(ban)(ban)(ban)在(zai)電(dian)路中主要起(qi)著導線(xian)的(de)作(zuo)用(yong)、固(gu)定(ding)的(de)作(zuo)用(yong)在(zai)電(dian)子管時(shi)代是沒(mei)有電(dian)路板(ban)(ban)(ban)的(de)，元件(jian)都比(bi)較大(da)，那時(shi)用(yong)到好(hao)多(duo)的(de)焊架來固(gu)定(ding)元件(jian)。用(yong)導線(xian)來連接。導線(xian)多(duo)時(shi)都有好(hao)多(duo)線(xian)把(ba)(ba)捆在(zai)一起(qi)。電(dian)路板(ban)(ban)(ban)使(shi)電(dian)路迷你化、直觀(guan)化，對于固(gu)定(ding)電(dian)路的(de)批量生產和優化用(yong)電(dian)器布局起(qi)重要作(zuo)用(yong)，帶有連通導體的(de)絕緣板(ban)(ban)(ban)，把(ba)(ba)電(dian)子元器件(jian)固(gu)定(ding)其上(shang)且聯成電(dian)路。簡單比(bi)如可以這(zhe)樣理解，線(xian)路板(ban)(ban)(ban)就是電(dian)子元器件(jian)的(de)載體。
