摘要
腰部偏孔是HDI板厂常见一种制程问题。其原因为板件局部变形所致,往往通过调整钻带系数无法改善,成为困扰HDI板厂的一大顽疾。文章通过对腰部偏孔的原因进行分析研究,试板层别,力图找到局部变形的原因并讨论改善方案。
Waist Hole-shift as common defects of HDI process,the reason is part distortion of PCB.It could not be improved throng adjusting dill belt scale.In this paper,through the study and analysis of waist holeshift of PCB,it did a lot of experiments and mass production verification of the possible reasons,and tried to find some effective solutions to discuss this problem with industry colleagues.
