solder practice, need critique and input

[Futuramille]

im waiting for esc covers to start a first build so practicing this evening. I've done normal hobby soldering for years, was ok .. this small stuff it taking some practice.
this is just a junk board. im also checking this paracord for around vtx and rx wires... maybe lol.

anyway, these joints test out, look fat though... will they do? i want the real thing to be looking whistle clean... any pointers?

thanks
jj

those were of course to the back side of pins like on the right shown empty here. i have several of these slinder pads to do and I've got nothing like that to practice on. any tricks to doing the 1mm pads?
I'm running 750deg (800 on those +/- wires)
i think the board in the first picture got too hot. i may need to wait longer in between?

 

[Futuramille]

and the only other joints to do are tho to this PDB.... and these pads are "largish".

one last question, regarding the battery input to that pdb... wth? do i just fill solder in around the wire? can the wire come out horizontally to the board? seems shaped for right angle but I'd like it straight out the side... how do i solder this correctly?
thanks for any pointers

Everything is looking pretty good. Are you pre-tining the wires though? Easiest way to make these small joints:

1. Pre-tin the wire
2. Pre-tin the pad (unless it is a through hole)
3. Place wire on top of pad, heat joint with iron until wire drops into solder to pad.

 

[Futuramille]

yes, that's the procedure. i think I'm most worried about heat. what temp do yall run on say.. the square pads on esc's? do you run same temp on the iron for most all these joints?
thanks a ton for the replies guys

 

[Futuramille]

im using one of these...

I solder most stuff around 700 to 750, might bump it up to 800 or 850 for large battery pads.

 

[theGreenOrange]

Also, you might use 63/37 solder instead of 60/40. It does take a little getting used to, but being eutectic, it makes cold joints basically impossible. There is no plastic phase during cooling like there is for 60/40.

 

[Futuramille]

thats what i needed to know Green, thank you sir! I'll have to try some 63/37 as well now. after years of radio shack irons, this new setup is so much easier (its more predictable) but a little practice yesterday got me close i guess. a little more practice today and ill be ready when the last bits arrive next week.
along with the esc covers is coming a new bnf micro (2") so its gonna be awesome!
thanks again Green!!

Any additional thoughts on the best approach soldering these PDB battery points?

Awesome post and advice .

750 deg. is way too hot. I'd use 400 or so

Tin all the exposed copper on pcb at joint and leads. Your gonna have to use helping hands so it doesnt move when soldering

 

[Futuramille]

do i just try and tin the ring and wire and start filling in?

750 farenheit

 

[theGreenOrange]

I can't say I have done one exactly like that, but I would do it just like you said.

yes, use something to keep it still

 

[VirtueViolater]

do front and back, keep it still with helping hands even when you already have one front/back side finished already

thanks for all the answers and help! y'all are great!
