Central Laboratory Introduction

Central Laboratory Introduction The central lab is public test service platform of Sunlord and has a Physical and chemical Lab , a Reliability Test Lab, an Electrical Testing Research Lab, a Simulation Lab and a Pilot Lab. The central lab owns numerous advanced imported test instruments and simulation software which provide structure analysis, material characterization, failure mechanism analysis, electrical specification research, EMC test , magnetism devices simulation, R&D experiments and small-lot production of electronic materials.

The Central Laboratory was formally established in 2011, covering an area of about 5000m2, with equipment assets of more than 100 million yuan. Currently, there are more than 100 professional laboratory personnel, and the expert advisory team mainly composed of product managers, R & D engineers and quality engineers. On the basis of being rooted in Shunluo, the laboratory has carried out extensive and in-depth cooperation with equipment solutions, third-party testing institutions, universities, etc., to provide strong technical support and all-round experimental services for internal and external customers of the company. In September 2016, Sunro Electronics and the world-renowned electronic measurement expert Shiside Technology cooperated to establish the "Sunro Electronics - Shiside Technology Electronic Measurement Joint Laboratory". The joint laboratory mainly conducts test technology research, test platform construction and talent cultivation in the field of electronic measurement based on the demand of CIS. In order to improve the management level and technical capability in the field of detection and analysis, we obtained the national accreditation qualification of CNAS in December 2017.
