Different soldering techniques

[BobK]

I was thinking about another kind of joint, the kind where one might wet one's whistle. And no, crystalline solder is not one of my favorite beverages!

... there's no point discussing something when you appear that you are unwilling to listen to good advice and many years of experience

All We all here can do is wish you best of luck with you soldering and just hope that not too many of your joints are dry

Aww, how unflexible(( Yes, I have my opinion about soldering, but that's not obduracy: I've tried both techniques and just want to understand, why some people fiercely prefer one of them (direct applying).

Steve amditted, that with additional flux bringing solder with tip may be OK. But, davenn, now I again hear undisputable allegation about "dry joints".

quality, reliability, and speed.

Sure, and it's also probably OK to have a non-temperature controlled soldering iron, or to use 50/50 lead/tin solder, or a whole other bunch of things. OK doesn't mean equally good.

Perhaps you can show us a video demonstrating your technique?

I thought about that It will take time, but I think I'm going to do that.

OK, I was able to make a vid. My camera makes movies in AVCHD, and it took time to convert it into some more widespread format (damned soft caused disorders to video).

Anyway, I hope it's good enough to see the main:

And, as video is not very nice, I provide couple of photos to compare the joints (red and black - direct applying, red and red - tip loading):

If comparing is not fair (for example, if you think I make direct applying wrong), please, just tell me.

ummm there's no video there
it says video stream not found

OK after reloading the site several times it finally worked

well your video so well demonstrates why the direct way is better as per steve's comments above particularly SPEED !

the direct method took a fraction of the time of a carry method the direct would have been well finished and another joint soldered whilst you were still playing around with putting the flux on the first joint!!

NOW let me see you do the same for a PCB with masses of joint like the ones I build....

wiping gooey flux all over the place and then messing around again with carrying the solder to the joint is just totally impractical
So so much faster and easier to do the direct method, which AGAIN is why its the STANDARD used

When I solder PCB, I just cover all the surface with liquid water soluble flux, it takes seconds Don't think I use the same flux for all purposes. Actions "take to to the pad + bring the solder to the pad + make joint" won't take more time then "load tip (if solder is set somewhere near) + take solder to the pad + make joint".

When I work with wires, I rarely have to solder wires, twisted like that. More regular is situation when I have to tin stripped wires, then I just stick every wire in the flux, it takes very little time. After that I don't need to degress from soldering itself.

Well, looks like I should make a vid about soldering PCB im my way.

At least, I hope, you'll admit that your words about dry joints were hurried, as joint, made by "tip loading" method isn't dry.

P.S. By the way, am I doing direct applying soldering right?
