What is the right design rules from JLCPCB? When I look at the electrical clearance from JLCPCB, I find: * Via to Via (Same net labels): 0.254mm * Hole to hole (Different net labels): 0.5mm * Pad to pad (Different net labels): 0.127mm * Pad to Pad with hole (Different net labels): 0.5mm * Via to track: 0.254 mm * Plated Hole to track: 0.33mm * Non Plated Hole to track: 0.254mm * Pad to track: 0.2mm * Minimum spacning: 0.09mm (4-6 layers) https://jlcpcb.com/capabilities/pcb-capabilities **Question:** Is this the correct settings of the design rules? [![enter image description here][1]][1] **Issue:** The issue is that it seems like a regular BGA footprint cannot even be produced by JLCPCB with those desgin rules. I have downloaded a sample CAD model from [STMicroelectronics][2] and it seems that all the rules from that model, violates the JLCPCB rules. Is that correct?
