Recently, I worked on some **PCBA samples** at MRCSS, and the overall performance has been outstanding! The circuit board design is precise, the soldering quality is excellent, and all components are installed correctly, ensuring stable and reliable performance. I especially enjoyed collaborating with **Sheldon**—his communication is quick and professional, and he provides timely feedback on details. The entire project has progressed very smoothly. I’m confident about moving forward with large-scale production!
