Splet21. okt. 2024 · So in our design, we have control only over the width of the traces. For most manufacturers, the minimum trace width should be 6mil or 0.152mm. That limitation comes from their manufacturing (etching) processes and the target yield. But to have some tolerance, we generally use 10-12 mil or 0.254-0.3 mm traces. SpletSoldering a copper wire will bring big gains as a standard PCB is 35µm. In comparison with a 1mm and a 2mm copper wire: A = h * w = 35µm * 1mm = 35 000 µm². A = h * w = 35µm * 7mm = 245 000 µm² ~1/7 resistance per length. A = r² * pi = (1mm/2)² * pi = 785 398 µm² ~1/23 resistance per length. SpletFor a 1A current, the width only needs to be 0.3mm. Given this, it seems impossible to run 10A of current through a tiny IC pad. It is important to understand that the trace width recommendations in IPC-2221 apply to a long PCB trace of constant width. corala 41 osijek
