PCB電路板（Printed Circuit Board）和PCB鉆咀（PCB Drill Bit）是電子制造過程(cheng)中的(de)兩個不(bu)同但相關的(de)工(gong)具和材料。

PCB電(dian)(dian)(dian)(dian)(dian)路板(ban)是(shi)一種(zhong)帶有導電(dian)(dian)(dian)(dian)(dian)圖案的(de)(de)板(ban)，用(yong)于在電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)組(zu)件(jian)之間傳輸電(dian)(dian)(dian)(dian)(dian)流。這些電(dian)(dian)(dian)(dian)(dian)路板(ban)通常由絕緣材料（如(ru)環氧樹脂(zhi)增強的(de)(de)玻璃纖(xian)維(wei)，即FR-4）制(zhi)成，上(shang)面(mian)覆蓋有導電(dian)(dian)(dian)(dian)(dian)層，這些導電(dian)(dian)(dian)(dian)(dian)層通過蝕刻工藝形成電(dian)(dian)(dian)(dian)(dian)路圖案。PCB電(dian)(dian)(dian)(dian)(dian)路板(ban)廣泛用(yong)于電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)產(chan)品的(de)(de)制(zhi)造(zao)，如(ru)計(ji)算機(ji)、手(shou)機(ji)、電(dian)(dian)(dian)(dian)(dian)視(shi)和(he)其他電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)設備。

PCB鉆(zhan)(zhan)咀是一種用于在(zai)PCB電(dian)路(lu)板(ban)上(shang)(shang)鉆(zhan)(zhan)孔(kong)的工具。這些鉆(zhan)(zhan)咀通常由硬質(zhi)合金(jin)或高速鋼制成，用于在(zai)電(dian)路(lu)板(ban)上(shang)(shang)鉆(zhan)(zhan)出連接(jie)點、安裝孔(kong)或其他所需的孔(kong)。鉆(zhan)(zhan)孔(kong)是PCB制造(zao)過程中的一個(ge)重要步(bu)驟，它允許連接(jie)器、插座(zuo)、電(dian)子組(zu)件(jian)和其他部(bu)件(jian)被(bei)安裝和固定到電(dian)路(lu)板(ban)上(shang)(shang)。

PCB電路(lu)板是電子(zi)組件的基礎結構，而PCB鉆(zhan)咀是用來在(zai)PCB上鉆(zhan)孔的工具。兩者在(zai)電子(zi)產品(pin)的設(she)計和制造中都(dou)扮演著關鍵角色。
