Dave, what size annular rings are on that PCB? They seem larger than what I use on my boards (10 mil). Is that board is for a kit, in which the larger pads are more helpful, or do you prefer larger pads?

[EEVblog]

@hotmessization Larger pads are useful unless you are limited for space.

Dave - Have you ever worked using a solder pot for small runs of through hole boards. If yes, would you consider creating a video showing how to do this?

BTW - Thank you for your excellent EEVBlog.

@gblive12345 No, never used a solder pot personally.

Dave do you think it is good practice when soldering IC's to skip a leg in between solder joints so that you don't overheat areas of the IC.

Ex. Say you're soldering a 555 timer chip, you'd solder pins 1 and 3 first, then move back to 2 and 4. Repeat on other side.

[EEVblog]

@Nadrealis It may keep the die at a lower temp, but in practice the device can handle either method. If I have multiple chips on a board, I'll often alternate between devices, just to let them cool more, just because I can.

Dave, another good tip you've forgotten to mention: solder tip in -> solder in -> solder out -> solder tip out. The soldering iron should always be the first thing to touch the joint, and the last thing to leave the joint. I realize you've done it all the time during your video, but the beginners could certainly not notice this detail unless we bring their attention to it.

(I'd also like you viewers to upvote my comment, so more people could pay attention to this detail.)

@radioguyuk thanks for your time, i will try that, i think i need more experience also, thanks again

[radioguyuk]

@chromatic1976 You probably need to add some flux, but old joints can be stubborn, try adding a bit more solder to the joint and then wick it away, see how you go.

[boubalos101]

probably the best video on the web about soldering! :D

[chromatic1976]

Hi Dave, I have trouble removing solder from older joints, the solder sucker doesnt seem to work very well and the solder wick doesnt seem to take away the solder. Do you have any tips to help desoldering plugs?

[sonus89]

How to make a perfectly good joint :)

[Riskteven]

7:53 I would guess a cotton stick with some Coke Light would clean this as well. That and another cotton stick with some water/spirit aftwerwards.

[warheadz]

Great tutorial, thanks!

[Psychlist1972]

I didn't think I'd learn anything new in this video, but now I realize I've been applying too much solder to my joints. :P

@Danvanm I have bought a chisel tip and has never gone back . FTW .
