Pad/pin1 orientation left for 3 or more pads: IPC in 2007: Upper left for 3 or more pads. The orientation in general is cathode/pin 1 on the left for 2 padsĢ. I’m now trying to pull together a few simple guidelines from the IPC-7351C standard for correcting my custom patterns. How to Generate BOM and Pick and Place File in DipTrace Where in DipTrace do I do edit current or new patterns to set the orientation correctly? Is there an approach in DipTrace I should be using to "standardize" any designs I make?ģ. In DipTrace what is the default initial orientation of a pattern? And what direction is the rotation in P&P? Clockwi8se or counterclockwaie?Ģ. I tried this today and it works for smts but I'd rather correct this problem in DipTrace as a design my boards.ġ. This tutorial recommends uploading the P&P file, visually checking each component, editing the original P&P file and uploading - repeatedly until all is correct. Checked a number of posts here, DipTrace help,, and only found a partly helpful DipTrace step-by-step from (see below). On my 1st attempt at outside pcb fab for my prototype, all the LEDs were placed backwards due to a pick & place rotation error.
