隨著(zhu)VLSI、電(dian)子零件(jian)(jian)(jian)的(de)(de)小型(xing)化(hua)、高(gao)集積化(hua)的(de)(de)進展，多(duo)層(ceng)板多(duo)朝搭(da)配高(gao)功能電(dian)路(lu)(lu)的(de)(de)方(fang)向前進，是故對高(gao)密度線(xian)(xian)路(lu)(lu)、高(gao)布(bu)線(xian)(xian)容量的(de)(de)需求(qiu)日殷，也(ye)連帶(dai)地對電(dian)氣(qi)特(te)性（如Crosstalk、阻(zu)(zu)抗特(te)性的(de)(de)整合(he)）的(de)(de)要求(qiu)更(geng)(geng)趨嚴格。而多(duo)腳(jiao)數零件(jian)(jian)(jian)、表面組裝元(yuan)件(jian)(jian)(jian)（SMD）的(de)(de)盛行，使得電(dian)路(lu)(lu)板線(xian)(xian)路(lu)(lu)圖(tu)案的(de)(de)形狀更(geng)(geng)復雜、導體線(xian)(xian)路(lu)(lu)及(ji)孔(kong)徑更(geng)(geng)細小，且(qie)朝高(gao)多(duo)層(ceng)板（10~15層(ceng)）的(de)(de)開發(fa)蔚為(wei)風氣(qi)。1980年代后(hou)半，為(wei)符合(he)小型(xing)、輕量化(hua)需求(qiu)的(de)(de)高(gao)密度布(bu)線(xian)(xian)、小孔(kong)走(zou)勢(shi)，0.4~0.6 mm厚的(de)(de)薄形多(duo)層(ceng)板則逐漸普及(ji)。以沖孔(kong)加工方(fang)式完成(cheng)(cheng)零件(jian)(jian)(jian)導孔(kong)及(ji)外形。此外，部份少(shao)量多(duo)樣(yang)生產(chan)的(de)(de)產(chan)品(pin)，則采用感光阻(zu)(zu)劑(ji)形成(cheng)(cheng)圖(tu)樣(yang)的(de)(de)照相法。

纖(xian)(xian)維(wei)(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)的(de)(de)缺點是背(bei)面(mian)有網(wang)紋，造成(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)材(cai)(cai)(cai)兩(liang)面(mian)表面(mian)積不等，OSB刨(bao)花板(ban)(ban)(ban)(ban)(ban)怎么用，吸濕后因產(chan)(chan)生膨脹力差(cha)異而使板(ban)(ban)(ban)(ban)(ban)材(cai)(cai)(cai)翹曲變形；硬質(zhi)板(ban)(ban)(ban)(ban)(ban)材(cai)(cai)(cai)表面(mian)堅硬，osb刨(bao)花板(ban)(ban)(ban)(ban)(ban)原料(liao)，釘(ding)釘(ding)困難，OSB刨(bao)花板(ban)(ban)(ban)(ban)(ban)廠商，耐水性(xing)差(cha)。干法纖(xian)(xian)維(wei)(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)雖然避免(mian)了(le)某(mou)些缺點，但成(cheng)(cheng)(cheng)本較高。組(zu)成(cheng)(cheng)(cheng)纖(xian)(xian)維(wei)(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)的(de)(de)基本單元是分離的(de)(de)木質(zhi)纖(xian)(xian)維(wei)(wei)(wei)(wei)或纖(xian)(xian)維(wei)(wei)(wei)(wei)束。制取(qu)纖(xian)(xian)維(wei)(wei)(wei)(wei)的(de)(de)原料(liao)主要來自森林(lin)采伐剩余(yu)物，伊春OSB刨(bao)花板(ban)(ban)(ban)(ban)(ban)，如(ru)(ru)枝椏、梢頭、小徑材(cai)(cai)(cai)等；以(yi)及木材(cai)(cai)(cai)加工剩余(yu)物，如(ru)(ru)板(ban)(ban)(ban)(ban)(ban)邊(bian)、刨(bao)花、鋸末等。此外還可(ke)利用林(lin)產(chan)(chan)化(hua)學加工的(de)(de)廢(fei)料(liao)（如(ru)(ru)栲(kao)膠(jiao)和(he)(he)水解的(de)(de)剩余(yu)物）和(he)(he)其(qi)他(ta)植物桿莖制取(qu)纖(xian)(xian)維(wei)(wei)(wei)(wei)。針葉材(cai)(cai)(cai)的(de)(de)纖(xian)(xian)維(wei)(wei)(wei)(wei)含(han)量(liang)高，纖(xian)(xian)維(wei)(wei)(wei)(wei)長度(du)比闊(kuo)葉材(cai)(cai)(cai)長30～50%。
