It is good for multi-channel and hierarchical design.In detail, here is why Altium is the best overall PCB design software in the market: Although it is a paid PCB design software, its budget is behind its flexibility and purpose to fit into different electronic project designing.Īltium has what you need to create high-quality printed circuit boards and automated electronic circuit design. However, there is one PCB design software that is overall the best PCB design software, Altium Designer. Each may differ from the other and may aim to complete specific electronic projects. Numerous software packages can help students and electronic engineers design printed circuit boards in fact, there are too many. I haven't used Diptrace, so I don't know how to create footprints in it.Which is the Overall best PCB design software? 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. 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. 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. The SOT23-5 is actually an incorrect designation, and should really be SOT25, though SOT23-5 is commonly used. The '3' portion refers to the number of pins on the package, so an SOT23 is a 2mm small outline transistor with 3 pins. The 'SOT' is a 'Small Outline Transistor', with 2mm distance between outer pins on one edge.
