[NSRCA-discussion] New Deans plug

Wed Jul 28 10:11:34 AKDT 2021

Everyone’s comments are right on but I thought I would add a couple more.

I use a 100 watt chisel tip stick iron.

It has more than enough heat to quickly do the job…..a small iron held on for a long time will melt everything. 

There are a couple of soldering techniques that go along with the larger iron….

I insert the plug/socket together then use a large hemostat on the other end of the contact I am soldering.

This acts as a heatsink and also stabilizes the work.

Clean everything with contact cleaner or lacquer thinner….it’s much more difficult to solder if the work has finger oil etc on it.

I use 16 gauge (.062) 60/40 solder….I get it from Mouser Electronics because I have an account….other sellers are just as good.

Made by MG Chemicals.

Liquid flux by GC Electronics.

This solder is a bit larger in OD so that you can quickly flood it onto the work and get a good job.

This takes about 3 to 4 seconds provided that the wire and contact are properly tinned….Peter has the right idea.

Use a lot of liquid flux….this is important because in addition to helping the solder to flow….it speeds up the entire job with less overall heat to the connectors. 

It’s really important to flood the wire with liquid flux before the tinning of the wire….the solder quickly wicks in as soon as the iron touches the wire…mebby 2 seconds….then quickly flood on the solder…..more is a lot better than less….as long as it flows.

10 gauge wire is easy to handle like this.

Flood on more solder when the wire touches the contact…..the connection needs to be mechanically strong as well as electrically low loss..

Flattening the wire with a hammer after tinning helps but I have had problems as soon as the heat hits the flat wire. 

Several strands always fly up and get in the way so I don’t do that anymore….I leave the wire twisted after stripping.

I’m pretty sure everyone in this crowd knows all this already but I have never seen anyone post any techniques on this list before.

It’s an art more than a technique…..

I found it helps a lot to have a jig to hold both the plug and wire stationary.

I wrote an article in the KFactor a few years ago and was re-run a year or so ago. It lays out the best way I have found to solder Dean’s. I have never had one fail. 

As mentioned , you need to tin both sides of the tabs. First bend out the positive tab a hair. This will give you additional clearance for the negative wire. Now tin the wires. The thing to remember is it takes a bunch of solder to tin the wire correctly. If I have had an issue getting a good bond, it’s almost always lack of proper tinning. Rotate the wire as you tin to cover all sides. 

Ok, here is the little trick that will save the day. As soon as you finish tinning the wires, squeeze the tip with a pair of pliers to flatten out the tinned tip. You have to get to it fast before the solder solidifies. This will give you additional surface area as the wire  lays on the tab. It will also give you more clearance.

I do a similar thing.  Tin the plug, tin the wire letting the solder really soak in.  Then Reflow the solder by pressing the wire to the plug with the flat of the soldering iron, the solder remelts and sinks quickly onto the plug, remove the iron and you have a rock-solid connection.

I found the key to soldering anything is to tin the plug and get a generous amount of solder on the wire. Heat the wire so the solder is fluid and then lay it on the tab and let the heat from the wire/solder to heat the plug under it. If you heat the plug tabs you’ll just melt the plug. 10g is a pita anyway, that’s why my systems use 12g. I’m sure I’m short changing myself with 1 Deans, 10S 6000’s and 12g wire but I rarely ever hit full throttle so I short change myself on the transmitter before my systems see it 😂

I talked to Deans yesterday.

 They have black and white ones in the works.

 Interesting that he claims that the Dean's ultra can carry much more of a load than generally thought of and is equal to a XT90 in its ability to carry the current. He claims anything over 50 amps continuous requires at least a 10g wire.

 The red ultra plugs are discontinued due to supply issues.

Yup....I went through 3 before getting one to bond.   

I wonder what they're made of ?.....Teflon is about the highest melting point plastic.

Cool.  I've turned many a Deans plug into slag soldering 10 gauge wire to the tabs.

Upon returning to the store Monday I glanced over at the connector isle in front of where I sit and saw a new Deans package I hadn’t seen before. It’s a white ‘high temp’ Ultra plug. Anyone seen/used one before? I’m going to use them on my CL batteries since I need to put plugs on them.
