This is such a calm, thorough, helpful video on a topic covered virtually nowhere else on the internet. It totally bailed me out. I was astonished how expensive these crimp tools are, but when you see the pin gripping the insulation PERFECTLY on your first crimp with one of these fellas, and feel how reliable is feels, you know why its worth it.
I was looking for reliable and safe connectors for making vintage audio equipment from the eighties more service-friendly. Many devices are more or less modular, but power cables are almost always soldered to the board, so I want to use wire-to-wire connections with the Mini-Fit connectors. Everything you said and showed about them has been a better and more comprehensive introduction than I could have ever hoped for. I left a like, both to acknowledge your great efforts put into the video and to find it again in the future when I'll design my own PCBs with Mini-Fit connectors in KiCad. Big thanks and Cheers!
Awesome video! Very comprehensive, well made video. I look forward to exploring your other content for useful information that will be helpful in my Arduino projects. Thanks very much. Regards.
This is a very thorough video of crimping the Mini-Fit connectors as well as the pros and cons of various wire strippers. I really expected to see a review of the Molex crimper only, and was really pleased to see you discuss others as well. You mentioned the motherboard connector; are the 6- and 8-pin power connectors for video cards the same type?
Hi, thanks for the comments! I believe they are the same type, Minifit JR, although I have not looked at any recent card (I use a laptop mostly, and a small server without any GPU card : (
The Molex tool is really expensive and it goes down to only 18AWG. I found a Knipex tool - not much cheaper - that goes down to 16AWG. It doesn't have the locator, though. The knipex is already very expensive for me but if I could I'd go with the molex tools.
GREAT VIDEO! This makes it so easy to understand! What I'm having a hard time understanding is why the crimp tools are so expensive? I looked at Digikey, and Mouser and they are over $500. Is there a reason for this? or am I looking in the wrong places? I checked ebay and they're still $250 plus. I was just looking to repair a connection in my oven, but the tool alone costs almost as much as the whole oven 🤯
Thanks for the comments! Unfortunately the Molex tools are expensive : ( however, there is a 'ServiceGrade' version of the tool, Molex code 64016-0200 which is intended for 28-16AWG Mini-Fit Jr. It's about half the price of the normal tool, but is only designed for a life of about 1000 crimping operations. If it were a low-current non-critical application, you could also consider cheaper non-brand crimpers, but for an oven, it's going to be a high risk, because the cheaper non-brand crimpers will not do as good a job, and the increased resistance will cause heating and could be a hazard. So really the ServiceGrade crimper is about the only option to save a bit of cost, granted it's not a big saving : ( You could sell it on ebay afterwards perhaps to recoup a bit of the money perhaps.
My issue with the molex connectors of any generation is their propensity to fuse together and stick and on disconnection the board connector is pulled off the board sooner than the connector disengaging. I know it is probably due to poor manufacturing standards and wrong tolerances but literally most computer hardware with molex connectors is a colossal pain to disconnect.

This video should have millions of views!
Thanks!
Perfect! Very calm, systematic and not in a hurry explanation. Thank You!
Hi Krasimir, Thank you for the feedback! I hope it was useful.
this is best VDO than other channel. next please make crimping electric terminal (insulated terminal, tabular lug, non insulated, F crimp B crimp Hexagon crimp O crimp)

Thanks for watching, and the feedback!
Very good production. Thank you.
Hi Chris, Thanks!
I love this voice :)
