Service Introduction

Given that the rapid development of rail transit industry in China, the manufacturing scale of rail transit products has been expanded, and the R&D cycle has been shortened, in addition, the control and competitiveness of products are facing with much pressures from domestic and foreign markets. During the life cycle of products, providing high-quality product and achievement of the low efficiency or even zero failure have become the important competitiveness of enterprises, which is also the challenge of enterprise quality control. The technical team of component screening and failure analysis in GRG Test is committed to the quality control and material reliability evaluation of the product life cycle. In addition, it has rich experience in technology fields such as the process quality evaluation of chips and semiconductor power devices, the service life assessment and the reliability test of electronic components and material components.
