HTW Testing and Certification Solutions.
1. The reason of radiation test failed
There are many reasons for EMC radiation tests failed according to the standard, such as interface filtering, cable design, grounding, shielding etc.
Generally speaking, it is the problem of PCB design.
For TCB, a multilayer board is a recommended choice, as it can reduce impedance.
The circuit on the PCB board is required to be straight and short.
2. The problems of product information
Label, Schematic, User manual, CDF/BOM, PCB layout
CMA, CNAS (17025), AQSIQ, IEC CBTL, US UL, A2LA, FCC, TIMCO, CEC, DOE, Germany TUV, EMCC, Japan VCCI, Norway DNV, NEMKO, UK ITS, Canada IC, Hong Kong EMSD and other qualifications have been obtained.
