印制板金屬化孔作為印刷電路板中的重要組成部分，在電子設(shè)備中發(fā)揮著非常重要的作用。本文通過(guò)分析印制板金屬化孔的靜態(tài)力學(xué)性能，探討了金屬化孔表面處理技術(shù)在可靠性方面的影響。從鉆孔到金屬化，通過(guò)對(duì)板材厚度、離子清洗等工藝參數(shù)的分析，對(duì)金屬化孔可靠性的影響進(jìn)行了深入的研究。

首先，本文對(duì)銅箔厚度與金屬化孔可靠性的影響進(jìn)行了探討。通過(guò)實(shí)驗(yàn)得出，在板厚0.8mm和1.0mm的印制板上，金屬化孔的可靠性分別為82%和78%。其次，本文分析了離子清洗工藝對(duì)金屬化孔可靠性的影響。結(jié)果表明，離子清洗工藝可以有效地提高金屬化孔的可靠性。

本文研究結(jié)果表明，金屬化孔的性能與制程參數(shù)、材料等因素密切相關(guān)。應(yīng)根據(jù)實(shí)際情況選擇合適的制程參數(shù)，確保金屬化孔表面處理的有效性和可靠性，為印制板生產(chǎn)提供有力的技術(shù)支持。
