Quality Evaluation Method for Integrated Chip Packaging Test Data under Non-Normal Distribution Using Line Chart Vertex Weight Accumulation
摘要
Abstract
In the early stage of integrated chip(IC)packaging and testing,the limited amount of data often leads to non-normal distribution,making it difficult to evaluate quality using existing process capability indices.This paper proposes a Line Chart Vertex Weight Accumulation Method that does not rely on the mean or variance.By filtering out extreme deviation data points using the 99.73%interval range and replacing the traditional process mean with the weight-accumulated mean of line chart vertices,the method enables accurate quality evaluation of IC packaging without depending on distribution assumptions.Simulation results show that this method provides more stable process capability index calculations compared to other non-nor-mal distribution approaches and can effectively detect quality issues at the early testing stage,thereby reducing packaging and testing costs.关键词
