日(ri)前，國(guo)家市(shi)場監督管理(li)總局(ju)和國(guo)家標(biao)準化管理(li)委員會聯合發布(bu)2020年第20號國(guo)家標(biao)準批準公(gong)告，由銅(tong)陵有色安徽銅(tong)冠銅(tong)箔(bo)(bo)公(gong)司牽頭主(zhu)持修訂的《GB/T 5230-2020印制板用電解銅(tong)箔(bo)(bo)》獲得正(zheng)式(shi)公(gong)布(bu)，并將于2021年8月1日(ri)正(zheng)式(shi)實(shi)施。本標(biao)準對印制板用電解銅(tong)箔(bo)(bo)的分類、外觀(guan)、尺寸、物理(li)性能要求、工藝要求、特殊要求、質量保證規(gui)定(ding)、檢(jian)驗(yan)驗(yan)方法、包裝(zhuang)、標(biao)志運(yun)輸及儲存等作出(chu)明確規(gui)定(ding)。

印(yin)制(zhi)(zhi)(zhi)板(ban)用(yong)電解銅(tong)(tong)箔是制(zhi)(zhi)(zhi)造印(yin)制(zhi)(zhi)(zhi)板(ban)用(yong)剛性覆箔板(ban)、撓性覆箔板(ban)、微波電路基(ji)板(ban)、涂樹脂銅(tong)(tong)箔等印(yin)制(zhi)(zhi)(zhi)板(ban)基(ji)材(cai)重要的(de)基(ji)礎電子材(cai)料，其質量優(you)劣直接影響印(yin)制(zhi)(zhi)(zhi)板(ban)基(ji)材(cai)和印(yin)制(zhi)(zhi)(zhi)板(ban)質量及其可靠性。

發(fa)(fa)達(da)國(guo)(guo)家已對印制(zhi)板(ban)(ban)用(yong)金屬箔(bo)的(de)分(fen)類、質(zhi)(zhi)量(liang)等級、金屬箔(bo)的(de)各(ge)項技(ji)(ji)(ji)術(shu)(shu)要求(qiu)、質(zhi)(zhi)量(liang)保(bao)證規(gui)(gui)定、試驗(yan)方法(fa)、包(bao)裝及標(biao)(biao)志(zhi)作出了明確規(gui)(gui)定，而之前我(wo)(wo)國(guo)(guo)GB/T 5230-1995《電(dian)(dian)解(jie)銅(tong)(tong)(tong)(tong)箔(bo)》僅包(bao)括標(biao)(biao)準(zhun)電(dian)(dian)解(jie)銅(tong)(tong)(tong)(tong)箔(bo)、高延展(zhan)性電(dian)(dian)解(jie)銅(tong)(tong)(tong)(tong)箔(bo)兩種電(dian)(dian)解(jie)銅(tong)(tong)(tong)(tong)箔(bo)，產(chan)品(pin)品(pin)種少，技(ji)(ji)(ji)術(shu)(shu)水(shui)平低，不(bu)能適(shi)應技(ji)(ji)(ji)術(shu)(shu)和市場(chang)發(fa)(fa)展(zhan)需求(qiu)，與(yu)市場(chang)需求(qiu)完(wan)全脫(tuo)節，使我(wo)(wo)國(guo)(guo)目前制(zhi)造印制(zhi)板(ban)(ban)和覆銅(tong)(tong)(tong)(tong)板(ban)(ban)大量(liang)使用(yong)的(de)重(zhong)要電(dian)(dian)子材料——電(dian)(dian)解(jie)銅(tong)(tong)(tong)(tong)箔(bo)產(chan)品(pin)檢驗(yan)無(wu)統一的(de)標(biao)(biao)準(zhun)，質(zhi)(zhi)量(liang)無(wu)法(fa)保(bao)證，成為制(zhi)約產(chan)業發(fa)(fa)展(zhan)的(de)瓶頸。因此，研究制(zhi)定《印制(zhi)板(ban)(ban)用(yong)電(dian)(dian)解(jie)銅(tong)(tong)(tong)(tong)箔(bo)》標(biao)(biao)準(zhun)，對印制(zhi)板(ban)(ban)用(yong)電(dian)(dian)解(jie)銅(tong)(tong)(tong)(tong)箔(bo)的(de)各(ge)項技(ji)(ji)(ji)術(shu)(shu)要求(qiu)作出具體規(gui)(gui)定十分(fen)迫切，該標(biao)(biao)準(zhun)的(de)制(zhi)定必將對指導我(wo)(wo)國(guo)(guo)印制(zhi)板(ban)(ban)用(yong)銅(tong)(tong)(tong)(tong)電(dian)(dian)解(jie)箔(bo)科研、生產(chan)、質(zhi)(zhi)量(liang)檢驗(yan)，規(gui)(gui)范市場(chang)、促進我(wo)(wo)國(guo)(guo)印制(zhi)板(ban)(ban)用(yong)電(dian)(dian)解(jie)銅(tong)(tong)(tong)(tong)箔(bo)的(de)發(fa)(fa)展(zhan)和質(zhi)(zhi)量(liang)提高及其上下(xia)游相關新興產(chan)業發(fa)(fa)展(zhan)發(fa)(fa)揮積(ji)極作用(yong)。
