在玻纖布的熱清洗工序中采用高于常規(guī)的溫度或更長(zhǎng)的處理時(shí)間進(jìn)行過(guò)燒處理，這種布稱作過(guò)燒布或脆化布。過(guò)燒布的特點(diǎn)是適當(dāng)降低布的抗拉強(qiáng)度，使布變脆，從而提高布的鉆孔加工性，改善孔壁質(zhì)量。 </p> <p> 過(guò)燒布一般控制在強(qiáng)度比普通布低20% -80% 。將兩種過(guò)燒布和對(duì)照的普通布用常規(guī)工藝制成雙面覆銅板，用仰mm 的鉆頭以60000 rlmin 的轉(zhuǎn)速， 25 mm 的孔距對(duì)三種雙面覆銅板作鉆孔加工性試驗(yàn)，試驗(yàn)結(jié)果如表5-3-23 所示。該表中例1 和例2 為過(guò)燒布，例3
