Service Introduction

During the traditional product development process, it mostly evaluates the EMC performance of the product according to standard tests after sample design and production. Once the EMC performance of the product is found to be substandard, it is necessary to locate the risk points and carry out the later rectification. At this time, it is often difficult to locate the difficulty of EMC problem, and the re-manufacture and testing of samples will inevitably cost more money and time. The EMC simulation method has the following advantages:

1) Shortening the R&D cycle and considering EMC problems from the design stage can reduce the repetitive work of sample preparation, testing and rectification, thus greatly shortening the R&D cycle;

2) To save R&D costs, employ computer software to carry out simulation modeling and using simulation results to guide product design can effectively save R&D costs;

3) Strengthening EMC control. Simulation design can strengthen the enterprise's control of product EMC and get rid of the dependence of product designers on experience.

Product Scope:

The products involved include chip level, cable harness, PCB board level, equipment level, antenna RF, system level, electromagnetic environment and battlefield level.

Relevant Qualifications:

We have purchased genuine simulation software CST, ANSYS, HFSS, etc., and several high-performance simulation servers for collaborative simulation calculation.

Test Cycle:

Depending on the project scale and project cycle, small projects will take about 1-2 weeks and several months to one year for large projects.
