Core Viewpoint - The article highlights the significant advancements in manufacturing processes at Sichuan Changhong Precision Electronics Technology Co., Ltd., showcasing the transition from manual labor to automated and efficient production lines, particularly in the SMT (Surface Mount Technology) and DIP (Dual In-line Package) processes [1][10]. Group 1: Technological Advancements - The company has upgraded its soft and hard board welding process from a two-step to a one-step process, achieving a production rate of 600 pieces per hour with a direct pass rate exceeding 95% [4]. - The PCIE connector manufacturing has improved from dual-sided welding to synchronized forming, maintaining a direct pass rate of around 98% [4]. - Single-sided board manufacturing has transitioned from glue-based processes to low-temperature reflow soldering, reducing auxiliary material costs by over 50% [5]. Group 2: Process Improvements - The medical electronics welding process has evolved from two separate weldings to an integrated fixture, increasing the first pass yield from 90% to 98.55% and improving equipment utilization by 24% [5]. - The introduction of magnetic pressure blocks and limit sliding fixtures has significantly enhanced the precision and efficiency of the welding processes [6][9]. - The company has implemented an AI-powered AOI (Automated Optical Inspection) system capable of identifying defects at a micro-level (0.01mm), contributing to improved product quality and production efficiency [10]. Group 3: Future Plans - The company aims to establish a PCBA (Printed Circuit Board Assembly) intelligent manufacturing factory within three years, targeting a doubling of individual output efficiency and achieving a quality level of 3.4 parts per million (ppm) by 2027 [10]. - The strategic focus includes the application of new processes, equipment, technologies, and materials to enhance manufacturing capabilities, particularly in the ICT electronics and automotive sectors [10].
