Many designs appear neat, but in actual soldering, insufficient copper rings prevent solder adhesion. The key isn't the drilling location, but whether a complete soldering surface can be formed after cutting; the copper ring width needs to be at least 0.15mm and wrap around the hole wall 360 degrees. Surface treatment is equally important; immersion silver is prone to sulfidation in humid environments, while excessively thick ENIG gold layers may cause..."}
