While trying to fix my daughter’s Nintendo DS (which wasn’t a complete success, I managed to replace the slot1, it powers up and plays games, but now won’t charge 🙁 ). I wanted to know what component “F1” may be. While Googling I came across a cached web page from pcbwizards.com which was down, but seems back now. So this useful info doesn’t get lost, I’m reposting the cached info here.
Reference Designation – Reference Designations are letter and number codes assigned to items that are part of an assembly. This ‘shorthand’ code allows components in a printed circuit board to be found easily while working on a board assembly or locating them and their complete descriptions in a Bill of Material or parts list.
Standard Reference Designations for Electrical Equipment can be found published in ANSI Y32.2 1975/IEEE STD 315. Below is a partial list of the reference designations used in electronics. |
