Household Liquid Heater Testing

Household liquid heater products generally include: hot kettle, coffee maker, water dispenser, electronic soup pot, etc.  And there are more and more intelligent control functions. For these products with intelligent control functions , there are more testing requirements for safety, EMC, SAR and so on.


HTW, has been focused on the testing and certification services in an early time, and we were certified as an IECEE CBTL. All these ensure our efficiency and accurate testing and certification capability.

experience in testing process.

1. the reason of radiation test failed

There are many reasons for EMC radiation test failed according to the standard, such as interface filtering, cable design, grounding, shielding etc.

General speaking, it is the problem of PCB design.

For TCB, multilayer board is recommended choice, as it can reduce impedance.

The circuit on PCB board is required to be straight and short.


2. the problems of product information

Label, Schematic, User manual, CDF/BOM, PCB layout
