Quality control

Runbo imply a strict quality control system, and in one corner of the factory, there is a reliability laboratory dedicated to issuing "QC Pass" for products. Every batch of mobile phones produced by Runbo is subjected to the most demanding experiments here. The experimental items include drop test, electromagnetic compatibility test, extreme condition test, temperature and humidity test, strong light test, aging test, etc. Strict reliability test enables early detection of potential reliability problems of products, and provides new products for new products. Design provides important information. Once the mobile phone fails the reliability test, the factory will stop the operation of the production line, and immediately analyze the reasons for the inspection, and the analysis report will be submitted to the company's project team responsible department.

The drop test is to make handheld and tablet perform a drop test from a height of 1.2 meters to hard still ground,for some practical models, this 1.2-meter-high drop test will be performed several times. And mobile phones that have passed the cyclic drop test still have to pass other design criteria tests.

In addition to temperature change factors, relative humidity will also affect the quality of the product, so the temperature and humidity test is the preferred standard in the field of quality testing. The Runbo products that need to be tested will be tested in an environment between -20 to +60 degrees Celsius and 93%-98% humidity. , the temperature and humidity change alternately, simulating the aging process of the entire mobile phone, and ensuring the quality of each Runbo product is safe and reliable.
