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.
