![]() ![]() Highly recommended for anyone who needs to design PCBs. The export options are also great for generating PCBs or Spice simulations. Its easy to use, and the auto-placement feature makes it a breeze to create complex designs quickly. BoardOutline.gbr Close the Export Gerber. Top.gbr Select Board Outline and click Export chose Yes to use the automatically apertures and save the File eg. I haven't used Diptrace, so I don't know how to create footprints in it. DipTrace is a great tool for creating printed circuit boards. Have your PCB Design Loaded in DipTrace and go to File /Export / Gerber Select the Top Layer and click Export chose Yes to use the automatically apertures and save the File eg. ![]() If a footprint isn't given, and it's a standard size like SOT25, then they assume it will fit any generic SOT25 footprint.īy the way, I use TI's SOT25 LM(something) regulators all the time (I forget the number off hand, might be the same ones), and just use the default SOT25 footprint in my PCB software and they work perfectly. The base version starts at 75.00, and allows you to work with projects having 300 pins and 2 layers. If you do need to make a new footprint you shouldn't be working from the chip's dimensions, but from the provided recommended footprint or "landing pattern" in the data sheet. DipTrace comes in a variety of pricing options and variants. ![]() In this case the -5 refers to a 5-pin version of the SOT23, which would be a 2mm small outline transistor with 5 pins, which by the above numbering scheme should be SOT25.Ĭhances are you will have a generic SOT23-5 or SOT25 footprint in Diptrace since it is one of the most common size of surface mount transistors / small devices around. To import the footprint: Open PCB Layout, click Tools > Pattern Editor. ![]() The SOT23-5 is actually an incorrect designation, and should really be SOT25, though SOT23-5 is commonly used. (C:Program FilesDipTraceLib) DipTrace will not allow you to edit in that folder. The "3" portion refers to the number of pins on the package, so an SOT23 is a 2mm small outline transistor with 3 pins. Used MC34063A to make a charger for lithium iron phosphate battery. The "SOT" is a "Small Outline Transistor", with 2mm distance between outer pins on one edge. ![]()
