The symbol for an ohm is the Greek letter Omega, which looks like this: Ω. 100MΩ translates to 100 megaohms. Other easy-to-identify components include oscillators (cylinders or boxes typically marked with X or Y), transformers (T), diodes (D), and relays (marked as K). Now look to see if the board has a fuse.
Step 3: PCB Design – Your Board Layout. Now it's time to draw the board. You need to transfer your schematic diagram into a drawing of your printed circuit board. This isn't as hard as it might sound. Because the software will compare what you are drawing to the schematics file.
