Crimping cables kind of sucks, but it sucks even more when your cables are poorly crimped and fail in subtle (or not so subtle) ways as soon as you finish screwing everything together.  Did you just order a couple thousand crimped cables from China and want to know if they’re well made?  Are you trying to make sure your own crimped cables are OK?  Molex has a great guide called the QUALITY CRIMPING HANDBOOK that sheds some light on what makes a good crimp.7

Want that in poster format to slap up on the walls of your lab or hacker-space?  Molex has got you covered there as well! English EU Metric version, for example.
