- Update: I bought the proper crimper and I have to say I am a convert to the correct way to do this now. So much better, quicker, cleaner. • Iwiss Ratcheting Crimper
Soldering some JST connectors for a project. I don't have the proper crimper, which may be silly, but is what it is. I started soldering small connectors like these after I had some crimped connectors fail when disconnecting multiple times. All it took was someone pulling from the wire and not the plastic holder for the wire to pull out. So I solder the wire on to the connector and haven't had a failure since. Often I am building for clients so I can't control who might be connecting and disconnecting my project components.
For the record, I am using a Hakko FX-888D soldering iron www.hakko.com/...
Lastly, this gave me a chance to try a two-camera set up. The top-down camera is a Canon EOS Rebel T6 with a 55mm lens www.usa.canon..... The side view was captured on an iPhone SE. Audio was recorded on a Zoom H4N www.zoom-na.co... using a Rode Lavalier mic. Audio was mixed in Adobe Audition CC and the video was compiled and edited in Adobe Premiere CC.
In the machine shop world we have the term "Order Of Operations". It makes the difference of a pleasurable experience to one that leaves you cussing at yourself.. Your soldering method Transposes this philosophy to the electronics bench. Leaving the connectors connected to the sacrificial ribbon and then soldering them satisfies that philosophy. I don't have a JST crimping tool yet so I soldered them the "much harder" way! I used an old steel brad that fit the connector snugly and hammered it into a board. It held the connector while soldering the wire to it. My method is much more work than yours but it does have a positive property. While the steel brad will not easily accept solder (that's a good thing here) it does sink heat away from the female aperture. Solder will defy gravity, as it seeks where the heat is and that's where my iron is too. If you're ever forced to solder one again try your method with a brad or better yet, a drill bit. It This method does a good job of discouraging solder from migrating into an area you don't want it to go.

You fine sir, should receive an award! Thank you very much for this amazing tutorial!
I just bought a cheapo $12 JST and Dupont crimper after attempting to solder wires to the JST metal connectors for a while, and I must say the crimping tool is SO MUCH EASIER and FASTER than soldering. The connections are excellent and the outerwings grab the insulator jacket so firmly that any mechanical pulls on the wire will be handled by that outside crimp.
I think soldering is the wrong way now - crimp tool for the win !
I never had any luck with the crimping but part of that is rushing. I'll have to look at it again. I know for large quantities of connectors, I don't want to be soldering.
I'm so very, very grateful for this video! I am currently working on a project with hardly any documentation as the parts I work with are from a wholesale source, meant for people who exactly know how use them. The fact is, I am not one of those people LOL. So I am figuring out a couple of things. In this project I ran into a slightly different kind of connectors, but the principle and the scale are the same. To be honest, I actually do not know the name of the connector. I have no crimp for this kind of connectors, but I do agree, the most reliable way to connect a wire to this kind of connectors is by soldering anyway. So I followed up your video, it works perfectly!
I love it that you do not use special tools. Special and expensive tools definitely have a reason to exist, but need not always be used.
In case a little too much solder is applied, making the connector too thick to fit, you can either redo the soldering, or use a fine file to make the connector thinner. Just be careful that while filing, you do not damage the cable insulator or the side that is going to make the actual connection.
All good points. I think, in a pinch, soldering is just fine. And it does make for a very secure connection. I have since bought a crimper and I quite like it. I'll still use the soldering method for more durable connections. For connection internal to a box that unlikely to move too much, I'll go with the crimper.
I used to solder them, but I finally spent $25 on a crimping tool. It goes like 10 times faster and the whole job is cleaner.
100%. I did the same.
Wow didn’t even think about doing it this way brilliant
I am not an expert in crimping nor one in soldering. But, I saw once how good crimping is done. I understood that they have two ports for crimping. The middle one is for the copper (stripped wire) and the farthest one is crimped over the sheathed wire. This way the crimping of the copper stays put and doesn't come out during normal abuse. What I saw in this video was not following the normal crimping position for the stripped wire. The copper portion of the wire should have been advanced to the middle crimp and soldered there. Even with soldering, this crimping is going to fail.
i've had no issues with soldering my connectors but you likely have a point. thanks for the insight.
Brilliant idea, seems so obvious now! I'm so glad I didn't blow my money on a crimper 👍
@andrew, I did buy the crimper. I have to say, it's very good. For other connections, on installs that travel and get jostled around, I'm likely to still use the soldering method. But I admit the crimper, when used correctly, is worth the money. I am due to make a follow up video.
Crimped connections are much more pliable than soldered connections, so unless you like constantly replacing wiring harnesses whose conductors have sheared off at the solder joint, get the crimper.
Soldering makes the connection brittle and only likely to fail under vibration etc. I do prefer the proper crimper and if done properly you can pull out the cable with the crimped end still on from the plastic end!
I have been meaning to do a follow up on this video. Since making this video, I did buy a proper crimper and fully endorse using a crimper.
The crimp tool is $20 and I also need it right now - this video showed me that simple soldering is going to work and others are doing it so my approach should be good to go.
It's a good solution if you don't have the proper tool and are paranoid, that's for sure. Since I don't have the tool at the moment, this seems the way to go.
Thanks for posting. Those little bitty connectors are a pain. The crimpers ‘usually’ work as you say and getting any good at crimping wastes a pile of connectors. This seems a straightforward method.
I think crimping is matter of practice. Once you nail it, you'll swear by it as others have said. I like soldering for small quantities of connectors. But I think I'll get the tool and try it out again. Maybe have a follow up distancing myself from this vid. lol.
Andreas Speiss has something to say about a WIS 2820m crimper. I found that method very easy to pick up and use on those tiny connectors.
@@j.hankinson7803 Yeah I ordered a proper crimper. Should arrive tomorrow. I just soldered 27 connectors and if I can save that effort long-term, I am down with it.
me too i like to solder 1st and crimp after 😉
Soldering makes it brittle so bigfoot can brake it off no problem. It makes my shorts all twisted my good sr. . Lol ! I see the age of this video and had to have some fun . You did a great job !
lol. Yeah. I posted an update once I bought the correct crimpers. If I wasn’t learning I’d be wasting my time.
That's exactly how I've been doing my connectors for many years. Fail safe and consistent. I still don't own a crimp tool for these connectors!
I have all the correct equipment for crimping, but there are times when I want solder and crimping. Then I apply a coat of solder or solder paste to the bare wire before crimping, and reflow with a heat gun after crimping. The crimp is solid, and the wire is soldered to the pin.
I have found something similar. If the use case means someone other than me is disconnecting and reconnecting plugs, I might add solder for strength.
Great video and explanation 👍👍
Great video! I noticed you're using silicone wires for your connections. I'm interested in the specifications of these wires - specifically, what AWG (American Wire Gauge) are they? I'm planning a similar project .
Thanks in advance!
I've been using 20AWG. I think maybe I could use a thinner gauge but it's worked so far.
I can imagine that tin goes easily too far into connector and blocks pin going fully in.. is that tho problem if soldering these?
if you're not careful and quick, 100% correct.
Spot on! We soldered connectors and it was a disaster for us (TL;DR: buy a proper crimp, it is worth it as the description update points out):
(1) when inserting in one board, the wire was pushed out of its connector, but worse
(2) in one expensive motor it went the other way round, the male pins on the receiving end were pushed through (inside the motor), then aaaargh...
Now we bought an Engineer PA-09 and will use it forever after 😅
Thanks for the vid man!
Crimping is superior to soldering, specially connectors that are made to be crimped.
Yeah, you're 100% correct. This video was made before I bought the proper crimper. I thought I updated the description but I'll double-check.
You’re god, thanks
Great tip. Great tutorial.

The solder flows into the top bit and the connector pins can't be pushed in anymore.
Yeah you really need to be conservative with how much solder you use.
There is good reason why they are supposed to be properly crimped - but at the same time there are many ways to skin a cat - so if it works , it works . However - see opening statement .
You're correct.
See, now I'm sad I pulled my wire caps off the belt for ease of storage.
On an unrelated note, I think I'll go buy a new belt of wire caps. (please don't shoot me if wire caps is the wrong word :p)
I keep mine attached because I have them in a box and my fingers are too clumsy to pull one single connector. (you can call them caps if you want, I won't judge).
@@hughqelliott I just didn't know the right term - connector it is :D
Where can I buy GH 1.25 pins (crimps) ?? I have precrimped wires and the plugs, but I need to make some custom length wires so looking for the GH 1.25 crimps on a band like you have in this video.
It all came in a JST connector set from Hiltichi off Amazon. I am sure you can buy just the connectors themselves from AliExpress. Easiest solution is the kit, though.
@@hughqelliott For some reason it is near impossible to find the crimps for GH 1.25 connectors. They sell the "pre-crimped" wires in a kit along with the GH 1.25 plugs but if you need longer custom wires and want to only by the GH 1.25 crimps they are nowhere to be found. So it seems the only solution is inserting (splicing) the necessary length in the middle of the pre-crimpted 6" wire. GREAT video by the way. Very helpful.
@@flyinlo1474 I decided to buy some crimpers. I've had mixed results but it is likely down to practice. www.amazon.ca/gp/product/B01N1RFZZ4
I do it all the time , probably better than the crimp to be honest.
Yea, probably soldering is more durable, but when it comes to prepare couple hundreds of those cables, well😅
@@lycankarmah1976 100%. I will buy the tool and try and get better at it. I have a project where I expect to be making 40 3-wire connectors. Soldering 120 connections will be a pain.

Much better than others thanks!
