Household Entertainment Devices
We are able to offer product testing and certification services for Audio, Video and Information Equipment, especially for household entertainment devices like video game machine, home theater, projector, TV set, stereo speaker etc.
As the complexity and sophistication of many household entertainment devices continues to increase. We have EMC, RF and safety testing capability with experienced technicians to to assist you in selling your IT/AV products to the global market.
HTW Lab, accredited by CNAS, CMA, CNCA & A2LA, consistently operates competently and generates accurate and valid results in accordance with ISO/IEC 17025. We are also IECEE CB Scheme Test Laboratory (CBTL), participating in IECEE CB Scheme. The CB Scheme is an international program created by the International Electrotechnical Commission for Electrical Equipment (IECEE).

1. The reason the 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
