PCBA物料主要涉及哪些?PCBA的中文(wen)意思是電路(lu)板(ban)組成(cheng)品(pin),就是一塊電路(lu)印制(zhi)板(ban)上,插(cha)上了(le)各(ge)(ge)式各(ge)(ge)樣的電子(zi)零(ling)件(jian),只要設計需要,什么電子(zi)零(ling)件(jian)都(dou)可以采(cai)用,工藝不(bu)外于插(cha)件(jian)焊(han)錫,貼片焊(han)錫,涉及到有(you)物料除印制(zhi)電路(lu)板(ban)本身(shen)外,常見的有(you)IC,電阻(zu),電容,電感,接(jie)插(cha)連接(jie)器,等等。。。
PCB的(de)(de)(de)(de)英(ying)文全(quan)稱為(wei)PrintedCircuitBoard,中文直接翻譯是(shi)(shi)「印(yin)刷(shua)(shua)(shua)電(dian)路(lu)(lu)(lu)板(ban)(ban)(ban)(ban)」,簡稱「電(dian)路(lu)(lu)(lu)板(ban)(ban)(ban)(ban)」,有人把它中英(ying)混合(he)稱「PC板(ban)(ban)(ban)(ban)」,印(yin)刷(shua)(shua)(shua)電(dian)路(lu)(lu)(lu)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)制造真的(de)(de)(de)(de)就是(shi)(shi)仿造書本紙(zhi)張的(de)(de)(de)(de)印(yin)刷(shua)(shua)(shua)技術,只是(shi)(shi)隨著科技進步(bu),印(yin)刷(shua)(shua)(shua)電(dian)路(lu)(lu)(lu)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)制造也越來(lai)越精細,而(er)(er)且越來(lai)越復雜。現今(jin)的(de)(de)(de)(de)電(dian)子(zi)(zi)產品之所以有那么(me)多(duo)的(de)(de)(de)(de)功能,基本上就是(shi)(shi)由一個一個電(dian)子(zi)(zi)線路(lu)(lu)(lu)與(yu)電(dian)子(zi)(zi)元(yuan)件(jian)組合(he)而(er)(er)成的(de)(de)(de)(de),而(er)(er)這(zhe)(zhe)些電(dian)路(lu)(lu)(lu)必須要(yao)有載體(ti),PCB就是(shi)(shi)這(zhe)(zhe)個載體(ti)。所以PCB基本上就是(shi)(shi)印(yin)刷(shua)(shua)(shua)有電(dian)子(zi)(zi)線路(lu)(lu)(lu)的(de)(de)(de)(de)板(ban)(ban)(ban)(ban)子(zi)(zi),負責連通(tong)(tong)電(dian)子(zi)(zi)元(yuan)件(jian)溝通(tong)(tong)的(de)(de)(de)(de)管道。一般稱呼這(zhe)(zhe)種已經印(yin)刷(shua)(shua)(shua)電(dian)子(zi)(zi)線路(lu)(lu)(lu)但還沒(mei)將電(dian)子(zi)(zi)元(yuan)件(jian)組裝上的(de)(de)(de)(de)PCB為(wei)光(guang)板(ban)(ban)(ban)(ban)或裸(luo)版(ban)。pcb打樣是(shi)(shi)指的(de)(de)(de)(de)什么(me)意思?
