<p> 扭曲變形的PCB板，整平的難度比弓曲變形的板難度要大一些，但只要操作得法，也可獲得良好的整平效果。 </p> <p> 關(guān)鍵點是要將扭曲變形的PCB板的對角線放入到弓形模具的中心線位置（待整平的PCB板與模具錯開45℃角），按上述方法整平，就可明顯減小扭曲值。上海偉奮實業(yè)有限公司為您提供環(huán)氧板，歡迎新老客戶來電！</p><div

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(qiáng)材料的一類基板。它的粘結(jié)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(jī)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(yīng)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(shù)和PCB 技術(shù)發(fā)展需要，又出現(xiàn)高Tg 的FR-4 產(chǎn)品。上海環(huán)氧板加工</p><p
