Yuda Electronic Technology Co., Ltd. (formerly YUDA ELECTRONIC LIMITED / Yostar PCB, renamed in 2026) is a professional PCB partner based in Dongguan, Guangdong Province, China.
Our core team has more than 10 years of hands-on experience in PCB engineering, quality control and supply chain management. We focus on helping overseas SMEs, R&D teams and design houses turn complex PCB designs into reliable, manufacturable products.
Instead of acting only as a “factory”, we position ourselves as your technical partner and quality guardian, performing DFM review, on-site production follow-up and detailed inspection for every project.
Reliability starts from inside each PCB. We perform micro-section and SEM analysis to verify copper plating thickness, hole wall integrity and layer alignment, especially for high-reliability and high-density designs.
Micro-section Analysis
SEM Electron Microscope View
Every batch of PCBs is inspected using high-resolution Automated Optical Inspection (AOI) and electrical testing (E-test). Our goal is to catch defects such as opens, shorts, missing pads or solder mask issues before the boards reach your assembly line.
100% AOI & E-Test Procedures
Oxidation and transit damage are two major risks during long-distance shipping. To protect your boards, we apply industry-standard vacuum packaging and ESD-safe cushioning materials.
