Is there a Standard/Guidelines that (or which IPC guidelines) defines the pad edge-pad edge clearance for Various via hole and component land sizes. Also defining why Vias shouldn't be placed under discrete components.

Hi Larry; Have you tried just to place it as a square. Or if all fails try vision 254 255. Just be carefull with this as it will place nothing if the reel runs out. Give me a call.

Larry, TRy using #254 and front light the part. When you define the leads leave plenty of tolerance and use a P-Pattern of 34.

Most MRP systems stink, because they do not understand that we buy a part made by a specific manufacturer from a distributor. They let you buy a part from a distributor, but they make it difficult to specify the distributors supplier. Ta Dave F
