| Pin header crimps that match SN-28B ? |

As this related thread mentions https://www.eevblog.com/forum/chat/crimp-tool-for-small-pins this tool needs much care to make a usable result. //Link corrected :) I've bought varous crimps on ebay, the longer ones are a bit easier to position in the tool. Usually though (a) There is some unwanted distortion is the resulting contact, it's a bit twisted (b) After some usage, the crimp's grip loosens and it becomes useless. This could be simply the pin header is a little larger then the crimp is designed to connect with. Given pin headers seem to be fairly standard though, I am not sure what the reason is. I'd be interested to know if there are crimps (pins and also sockets) which work especially well with this tool. |

That link didn't work for me.

That tool is covered in the other thread. |

Thanks for correcting the link. Yes the tool is mentioned as you say - I'm really after a current good-value source, maybe eBay, of pins known to work well with this, by someone who has used this tool a fair amount. I have just been using the tool today. The problem is that some of the crimps are a bit short. This means the part which should 'clink' into place inside the header mouding gets squashed. It is usually rather hard to tell from photos of crimps how these would sit inside the jaws of the SN-28B (mine is branded "WEIERLI"). |

Maybe this thread is worth a read as well on this topic: https://www.eevblog.com/forum/reviews/affordable-crimp-tools-for-small-connectors-(dupont-etc-)/ |

Your design(s) should determine the best pins for the purpose. Then you get a crimper to work with those pins. That is apparently a poorly made generic crimper. Maybe the best fit would be the cheapest made in China pins you can find. |
