Acceptable - Class 1,2,3(可接受条件 - 1,2,3级)
No evidence exists that pink ring affects functionality. The pres-
ence of pink ring may be considered a process indicator but is not
nonconforming. The focus of concern should be the quality of the
lamination bond and hole cleaning and conditioning processes.
没有证表明粉红圈影响印制板的能。粉红圈的出现可
将其为制程示,但不是不符合状况。应该将关
点放压粘接和与处理制程的质量上。
