Re: SC-70 patterns named SOT23

It looks like the search engine is including " Additional Fields " for some unknown (to me) reason. I see " SC-70-5 " in the Unique Name field of the first item in the search list that uses a SOT-23 pattern. ...EDIT... Assuming the Wikipedia article on the small outline transistor found here https:/...

Re: QFP pattern help

Well, trying out the Pattern Editor's IPC-7351 pattern generator and plugging in the MicroChip-recommended dimensions (including pad size) produces the name " QFP64P50_1200X1200X120L60X22 "... MC_QFP.png If you search the standard DipTrace pattern libraries for similar names, the Nominal density " Q...

copper pour option changes - take 2

The suggestions below were inspired by this thread - viewtopic.php?f=24&t=13464 , which is an example of a workaround that should not be necessary. I think it would improve usability if the options under the [Border] tab of the Copper Pour Properties dialog window were changed to reduce some confusi...

Re: Moving pads from top to bottom

* In the Pattern Editor right-click directly over a pad (or one of a group of selected/highlighted pads) and choose " Change Side " in the context menu. * In the PCB Layout editor slowly move your mouse towards the outside perimeter of a pad until it is highlighted in green (default Pattern Highligh...

Re: Drill to PAD Clearance

If you prefer to keep the 2mm diameter lens opening, the stock pads could be trimmed as shown below to maintain a passable gap size. As seen in the previous example a small amount of terminal-to-pad contact area will be lost, but if you think you would like to try this method I can post a DXF file w...

Re: Drill to PAD Clearance

Other than hoping the DipTrace developers add a " [x]Suppress Error " option to each line of the DRC report some day (I would like to see that), you might consider customizing the pattern to just barely pass the current rules. In the example below (units = mm ), pad size has been changed to 1.44W x ...

Re: Drill to PAD Clearance

Who is the manufacturer and what is the part number of the LED being used? (Does it have through-hole or SMD pads?) Are you using a pad for the light port or are you using a mounting hole? It might help if you could post screen shots of the following... * Your Design Rules dialog window (click on it...
