This article uses real-world examples to explore how to move beyond blindly pursuing copper thickness and surface treatment specifications, and instead focus on the supplier's true process capabilities and design understanding. Through aspects such as production line details and equipment configuration, we help you identify which manufacturers are truly worth collaborating with, avoiding being misled by flashy certifications and empty promises."}
