During the production of Douai , the defective percentage is strictly under control. Quality is guaranteed by rigorous control and monitor of each production process to meet the quality standards required in the electronics industry.
g******e
Douai is produced in a dust-free and bacteria-free workshop in which the temperature and humidity are strictly controlled and monitored, so as to ensure its high quality.
h******u
Douai adopts both manual soldering and mechanical soldering in the production. Combining these two soldering methods greatly contributes to reducing the defective rate.
e******g
Douai is developed by adopting the most advanced integrated circuits technology. The R&D team makes the transistor, resistor, capacitor, and other components gather together to achieve a compact design.
h******n
Douai has passed the anti-static and electro-static discharge tests required in the electronics industry. The product has high sensitivity to ESD, protecting people from the harm of discharged electric.
x******w
It is refined from high-quality plant fibers, and has good wear resistance, crack resistance and bending resistance in the washed state.
