I made a little breakout board for a chip I wanted to try out. It’s a current sense amplifier, so I put a spot for a shunt resistor to monitor. Can you spot the problem with my layout?
No? How about now:
Even if you had Lincoln’s tiny eyes you might have trouble making that out because text that size is at the limit of the silkscreen’s (or, probably, the inkjet’s) resolution. The software will zoom in with infinite resolution when you’re laying out the board, so there’s no warning when things get small. You have to keep track of the units. In this case, the text is 16 thousands of an inch.
