FR-4環(huán)氧板是以環(huán)氧樹脂作粘合劑，以電子級玻璃纖維布作增強材料的一類基板。它的粘結片和內(nèi)芯薄型覆銅板，是制作多層印制電路板的重要基材。 </p> <p> FR-4環(huán)氧樹脂板的機械性能、尺寸穩(wěn)定性、抗沖擊性、耐濕性能比紙基板高。它的電氣性能優(yōu)良，工作溫度較高，本身性能受環(huán)境影響小。在加工工藝上，要比其他樹脂的玻纖布基板具有很大的優(yōu)越性。這類產(chǎn)品主要用于雙面PCB ，用量很大。環(huán)氧玻纖布基板，應用普遍的產(chǎn)品型號為FR-4 ，近年來由于電子產(chǎn)品安裝技術和PCB 技術發(fā)展需要，又出現(xiàn)高Tg 的FR-4 產(chǎn)品。 </p><p style="text-indent:25px">黑色玻璃纖維布壓制固化成型壓制固化成型分三個階段,即預熱、熱壓和冷卻,特種環(huán)氧板還必須在熱壓成型后進行熱處理,即補充固化。(1)預熱階段將疊坯料盒裝人壓機熱板間,合攏熱板,而后給壓1~3MPa,給溫至100~120℃,并保持25~45min,使預漫漬料中的樹脂進一步浸透到玻璃布纖維的空隙中去,同時也可使揮發(fā)物進一步溢出。若預熱溫度過高則易流膠、甚至跑料(坯料滑出熱板間)以及導致層壓板表面麻孔;若預熱溫度偏低且時間不足,在熱壓階段升溫加壓過快,會導致被壓物滑出。環(huán)氧板，就選上海偉奮實業(yè)有限公司，讓您滿意，歡迎新老客戶來電！</p><div
