Quality Control

In most areas, the average temperature is around 0°C~40°C, and during the winter, the temperature is around -32°C~-46°C. Chances of temperatures being under -51°C is less than 20%. The environmental setting of consumer electronics are usually between  +5°C~ -5°C; telecommunication products and industrial product, due to life expectation, usually are between-5°C~-20°C. For products exposed to a long period in an outdoor environment (e.g. LED street lights), a lower limitation shall be set for the low-temperature, say -30°C or -40°C for adequate accuracy to be obtained.

To precisely inspect and verify the product’s performance under cold temperature conditions, International Electrotechnical Commission (IEC) has standards for preconditioning, post testing conditioning, temperature rising speed, constant temperature definition, temperature load condition, unit under testing and chamber volume ratio and so on.

Button life testing machine is suitable for mobile phones, computers, electronic dictionaries, Bluetooth headsets, car players, remote control buttons, vehicle alarms, fax machine buttons, MP5, MP4, MP3, button switches, touch switches, membrane buttons, rubber Keys, silicone keys and other keys are used for life testing. This machine is to put the product in the test position of the corresponding station, and the key test bar simulates the life test of the product under a certain test load, speed, stroke, and number of times.

The cables will be bent during consumers are using the earphones at different intensities. It tests the limit of the number of bends at a certain strength. 

Simulates the salt spray test of seawater that the product will undergo during the shipping process

Simulation of vibration testing of products during the transportation. 

Dropping the headphone from certain height to test whether the structure of headphone is stable.

It is used to test the corrosion resistance of a product in an environment that mimics the atmosphere.

Anechoic chamber for test ANC earphone. It is immensely quiet and with no room reflections. This makes it ideal for testing very quiet products or hearing very quiet sounds. (For ANC headphone).
