When you place a resistor such as 'RES-US1206FAB' it doesn't have a value.Do not mix names (I've seen some schematic where the +5V symbol was linked to a net names 'VCC'). For VCC/+5V & GND use the symbols from the 'supply1' lib.Read this Sparkfun tutorial and check Charles' design for examples. It's really hard to read a schematic with only wires, or with only net names. Now that I have reviewed some of your schematic and PCBs I can summarize the most common issues. "A how-to guide to taking your electronics project from prototype through to high volume PCB manufacture." The Engineer’s Guide To High-Quality PCB Design
Good overview of the design process, lots of picturesĪltium Designer Tutorial: Schematic capture and PCB layout Note that Sparkfun provide free libs for the products they sell. Trace? Via? Silkscreen? Gerber? Double-sided PCB? All the answers are on this link.Įxcellent tutorial if you want to use EAGLE. This tutorial will breakdown what makes up a PCB and some of the common terms used in the PCB world." It’s so fundamental that people often forget to explain what a PCB is. "One of the key concepts in electronics is the printed circuit board or PCB. Scroll down to see the class specific FAQ and to get the DRU file. Here's some information regarding PCB design.
