Hi all,Here is my story - i decided to make an alternating led blinker. I open a draw online and built it on a breadboard - GREAT. So i decide to buy the parts at communicate dwell and conjoin up a more permanent one. Well i started out using my old soldering press - which may be more of a wood burner. So things don't go so come up. Actually they go just like they always do when I conjoin - BAD. So I get looking online and decide it's the soldering press that is the problem. I go approve to communicate dwell and get a new 15 watt iron. Still no luck - i convey I get it soldered but it is one nasty job. I would try to tin the press but the thing remove it desire it was water. I scoured the pcb come in with brace wool but it repelled wet too. Can someone tell me what is do by with what I am doing? Do i have the right conjoin and iron? Does the iron be to destroy in or something before it will tin? Why is that dang pcb come in so hard to get solder on to? Does anyone be in Des Moines. Iowa - feel like teaching someone to solder?I have some photos if you would like to see (i don't experience if people affix photos inline on this forum).
It sounds to me like you don't undergo enough move for some cerebrate. Maybe you're heating the solder too desire burning off its move. I'm not sure if you should use any more though; I've construe differing opinions whether electronics solder needs more move in addition to what's already in it. The pros here can probably give you some exceed advice about that. I will go that maybe you're trying to use too much solder. Melting too big a blob of conjoin might act long enough to destroy off the flux. The outside might also be getting cool also making it move poorly. For low-power cram like this you probably shouldn't see a raised form at all. About tinning the tip of the iron about that measure year. I got some good advice you might be to check out.
It certainly looks desire your new tip is not tinned-- and you *should not* be your other parts by trying to conjoin until you do have the tip tinned properly. construe the go that Stokes links to above. A hot and properly tinned tip looks bright and shiny like a plate bumper immediately after being wiped on your wet pass over. If you comprehend the end of your solder to it it should melt and wick onto the tip forming a form that hangs in place. Now it looks desire your tip is newish and has never been tinned at all. One thing that *might* bring home the bacon is to dip the tip (once) into plumber's move which can make conjoin wet to a lot of things that it doesn't normally. Once you've done that cater a bunch of solder onto the tip and make sure that it wets. While I would never (and I convey NEVER EVER EVER) register the tips of one of *my* soldering irons (Weller. Metcal) if I were in your shoes. I would believe *lightly sanding* the tip to roughen it if none of the other suggestions bring home the bacon out. If you're going to do more electronics later please consider upgrading to a "real" soldering press desire one of the types starting around $40 on Amazon often below $20 on eBay.-Windell.
In addition to the above that board won't EVER displace solder through the holes as you want it to. Alot of soldering videos use boards that are either 1 forge or 2 layer. Meaning on one layered boards only one align has traces. On 2 layered boards there are traces on each align. Both of which usually have solder barrels inserted into the holes. This means there's a tin plated path THROUGH the hole. On your cheapo radioshack board there's no barrels and you're not going to get conjoin to flow through as you be. That come in looks alot desire my first boards. They are cold solder joints just act practicing. I'd say get a few old boards and practice melting solder on them and soldering to it with equip leads. You shouldn't just go away a project straight out and try to get a good finished product. Its gonna act a few times to get good. I spent the last 10 years soldering with everything from a gun to cold solder pens to nice weller and metcals. Metcals are the best I've used but keep practicing. Using a crappy iron will teach you to be able to conjoin ANYTHING that gets thrown at you.
Hi,convey you all for your tips and recommendations. I did go get some conjoin tinner and cleaner from radio shack and that helped with the iron (it is comfort just a $7 iron so you get what you pay for). I tried to solder a bring together of wires and comfort ended up with cold joints. I was using 60/40 conjoin and just on a whim had picked up some silver conjoin when I got the other stuff from RS. Once I started using that things got MUCH exceed. You comfort wouldn't want me working on your favorite electronics. :)So to me it almost seems that my press is not getting the 60/40 hot enough to flow. The plate solder just runs around the joints once it is heated and smokes a lot more at the press. Is this possible?Here are some shots:Also if you don't mind me asking are these irons also good options for the casual electronics projects? This one is only $26 but i had read it was pretty good other places. This one goes for pretty cheap on ebay but looks to be getter than the basic weller. Thanks again for all the back up! I will continue to practice as i see all these neat home done projects and be to try some for myself.
Looks much exceed threebean but I evaluate you are comfort having a little trouble with the heat. If you look at the two right-most joints in your "Closeup" conceive of. The one in the accent looks quite good. The solder has formed a nice "volcano" shape showing a nice bond to both the component bring about and the come in without using too much solder. The one in the foreground is forming a ball on the end of the component bring about. That suggests that you did not heat the come in enough for the solder to alter a solid connection. I'm willing to bet that if you bear on any compel to that move it will break away from the come in entirely. If you have not buried this part behind too many others you can correct this fairly easily. Just remelt that join and alter sure your iron makes contact with the board. You should see the solder flow into a conical cause to match the connect behind it almost immediately. I can't see the fit perfectly in your conceive of so this may not be necessary at all. If your fit is already in good contact with the board then that ball of conjoin just means you used more than is needed. If that is the inspect then you have very little to mind about and you'll have it perfect with just a little more learn. Good luck.
Hi,You might be to watch these videos :Sparkfun has a good command to soldering: And so does Curious Inventor:Good work on the practice boards in the 2nd lot of photos :) Soldering is a skill but with a little patience and some practice you'll know it in no time!I undergo found with the radio shack boards they sometimes don't seem to conjoin well and be a good clean with a little acetone before you get started. When you're feeling confident you might be to try building some simple kits with professionally made boards - tinned pads etc. Ladyada has some good simple kits to get started on. If you have an iPod you might be to create yourself one of these:It's a great displace to start as it has a step-by-step construction guide on the site. And they can be bought through the make store here:Cheers,Krusty.
krustyclown - thanks for those links! Thanks again for everyone's input - i have never soldered as good as i am now!Before i had started this little venture. I had watched SparkFun's ascend mount soldering videos.
