The quality system of Stitch laptops runs through the entire production process and covers the entire product life cycle. The core is divided into four major control links, which are checked layer by layer and strive for excellence: firstly,Source controlEstablish strict component screening standards, conduct multidimensional testing on nearly 2000 core components such as processors, screens, and batteries, screen high-quality suppliers, and establish long-term cooperation mechanisms to prevent unqualified components from entering the production line from the source and build the first line of defense for quality; Secondly,Production controlRelying on an intelligent production line with an automation rate of over 90%, precise and controllable assembly, bonding, debugging and other processes are achieved. The AI visual inspection system checks production defects in real time, and engineers are on duty throughout the calibration process to ensure that each process meets strict standards and avoids human errors; Thirdly,Full item testingEstablish a professional testing laboratory and carry out over 200 full process testing projects, covering performance testing, environmental testing, durability testing, etc., including high and low temperature limit testing, endurance stability testing, keyboard typing life testing, etc. The testing accuracy is comparable to industry benchmarks, and the defect rate is far below the industry average; Fourth,terminal controlBefore leaving the factory, the final round of complete machine inspection is carried out, and an after-sales quality traceability system is established. Each device has a dedicated quality code, which can achieve full traceability of production, testing, and delivery, respond to user feedback in a timely manner, continuously optimize quality, and protect the safe use of every user with a full chain quality system.
