电路板高密度化倾向,使得细、密线路板成为业界广泛的发展方向,而线路等级75μm/75μm甚至更细密之线路板,已在多家PCB制造商批量生产。然而,由于外层前处理参数、方法、物料管控不当产生的外层良率降低及报废飙升,令众多业者痛心疾首,望板兴叹。本文通过对与外层前处理相关的案例进行解析及探讨,希望为同行业者带来有参考价值的资料。
電路闆高密度化傾嚮,使得細、密線路闆成為業界廣汎的髮展方嚮,而線路等級75μm/75μm甚至更細密之線路闆,已在多傢PCB製造商批量生產。然而,由于外層前處理參數、方法、物料管控不噹產生的外層良率降低及報廢飆升,令衆多業者痛心疾首,望闆興歎。本文通過對與外層前處理相關的案例進行解析及探討,希望為同行業者帶來有參攷價值的資料。

High-density tendency of printed circuit boards has made the boards with ifner and denser circuits widely-accepted in the industry. Boards with line width and spacing of 75μm/75μm or even smaller than that, have been massively produced in many PCB manufacturers. However, the decreasing of out-layer yield and the soaring of scrap rate due to the improper controlling of the parameters, methods and materials in out-layer pretreatment process, has frustrated many manufacturers. This paper, through the analysis and discussion of the cases related to the out-layer pretreatment, is intended to bring the manufacturers with useful information for their reference.
