    • A method for cleaning a surface of a resin layer capable of sufficiently improving peel strength of a metal film formed by plating on a surface which is roughened by performing a desmear treatment on a resin layer containing a resin added with a large amount of filler is provided. The method is characterized in that, when a surface of a resin layer on which a metal film is formed by plating is roughened by a desmear treatment and, then, the thus-roughened surface of the resin layer is cleaned, the surface of the resin layer formed with a resin compounded with a filler in an amount of 20 wt % or more such that a difference of a coefficient of thermal expansion between the resin layer and the metal film is allowed to be reduced is roughened by subjecting it to the desmear treatment and, secondly, the filler which is deposited on the thus-roughened surface of the resin layer is removed by ultrasonic cleaning in which ultrasonic vibration of a frequency of from 35 to 50 kHz is applied.
    • 提供一种清洗树脂层的表面的方法,该树脂层的表面能够通过在含有添加有大量填料的树脂的树脂层上进行去污处理而将通过电镀形成的金属膜的剥离强度充分提高到粗糙化的表面上 。 该方法的特征在于,当通过电镀将其上形成金属膜的树脂层的表面通过去污处理进行粗糙化,然后清洁树脂层的这样粗糙化的表面时,树脂的表面 由树脂层和金属膜之间的热膨胀系数的差减少20重量%以上的与填料混合的树脂形成的层进行粗糙化处理 其次,通过施加频率为35〜50kHz的超声波振动的超声波清洗除去沉积在树脂层的粗糙化表面上的填料。
