Components Test

Our country has a wide area and great differences in climatic conditions, the vehicle interior and exterior trims and electronic components are easy to be damaged under the severe climatic conditions such as atmospheric environment temperature, humidity, corrosive medium, sandstorm, rain and snow. During the development of intelligence, electronization and networking, the implementation of new products needs to be strictly verified.

(II) Technical scheme

EMC design: EMC design control is carried out through multiple dimensions such as EMC test index decomposition, EMC component selection, system power supply and grounding layout, product schematic diagram, product structure cable, PCBLayout, etc. In addition, EMC simulation can be verified in combination with relevant design parameters to ensure that product design passes EMC test acceptance at one time.

EMC simulation: the simulation platform built by the Institute of Electromagnetic Compatibility of GRG Test can not only effectively evaluate EMC performance and status through computer software, but also guide EMC design of products. By using EMC simulation, the design cycle of products can be effectively shortened, and the one-time passing rate of EMC tests for products can be improved.

EMC rectification: for the failed test items, GRG Test analyzes and finds out the potential factors causing the failure in terms of the structure, principle, layout, software and technology according to the product characteristics and test principles. At the same time, based on the existing structure of the product, effective rectification and debugging are carried out through a series of means such as fine adjustment of circuit device parameters, wiring harness and layout adjustment, port processing, shielding and grounding improvement, etc. thus ensuring the qualified result of the test and forming a formal rectification plan report after qualified.

EMC technology training and consultation: circuit principle design, production process design, PCB electromagnetic compatibility design, shielding mechanism, structure design and customized training.
