Soldering tip/help....

**K3N[ShadyLTD]** · 05-24-2005,05:02 PM

Just wondering. I started practice soldering yesterday, i want to know i could get some feedback on how well im soldering circuits.

Just wondering, is this the proper way of putting solder on a wire ?

I was able to solder one item on the pcb of a linksys circuit board, im starting to get a good idea on soldering. But i think i'll be practising more and more, until i can get a 30 gauge wire. Also if you guys dont mind , i'd like to post in this thread just to get feedback on the soldering, and how i could improve.. Thanks in advance.

Add some solder to your solder iron just enough to wet it, take the wire place it close to the solder iron tip basically in parallel about 1mm away from the tip, then take the solder press it against the wire (at a slight angle) the solder is touching both the wire and soldering iron tip and the solder wire pushing the wire onto the tip as well, let it melt and if your using really big wire rotate the wire a little, cut the soldered piece of wire to the desired size.

Alright, thanks for the tip. And also i should put a tiny bit of solder on the part of the pcb im soldering onto right ? I tried not to do that, but the the soldered wire refused to stick. Then i put a small amount, within the area of the unit, and the wire (with solder on the tip) was able to stick/connect.

YOu need to add a slight amount of solder to the part you want to solder to,to do this,add a small amount of solder to your soldering iron,place the solder wire ontop of the thing you want to solder to,place the soldering orin ontop of it(at about a 30 degree angle) and slowly feed in some extra solder,dont hold your soldering rion there for longer than 3 seconds,lift it(the iron) then place the wire that you allready added solder too ontop of it slowly put the iron ontop and add a slight amount of solder 3 seconds again,lift the solder iron and tug the wire that you soldered slightly to test if its making good contact,do all of this with the minimum force nessesery.

AND PRACTICE PRACTICE AND PRACTICE...

BTW I don t mind helping you now becouse you want to help yourself aswell.

Alright i'll keep that in mind. I practised about an hour of soldering yesterday , but im not perfect. I will practice some more later to day. Also, i have a good idea on how desoldering braid works . But im a little puzzled with the rosin flux i got. Its a not a liquid spill type, its the paste (brush included) type. It says on the directions to , 1.) heat parts (huh) 2.) melting flux (so i put flux paste on the pcb and then heat it? ) 3.) apply solder.... Im a little confused with steps one 1 and 2, may someone please clarify them?

Id appreciate it if someone told me how to use flux please. I got a 30 gauge yesterday , and im finding it difficult on how to put on the the several pins, located on the sides of the black fuse.

What do you guys think about this soldering on the modchip, i did it myself... I the solder is about .7/10th (not 7, .7)of an inch high from the modchip.. again, id appreciate the help..

**fasman** · 05-26-2005,04:39 PM

The solder on it is very gritty,it sould be a nice reflecting surface on it,you used old solder on it (put too much on the soldering iron and tried to use that) or you werent quick enought,as for the flux paste,take the brush apply a little to where you want to solder wait 60 seconds and solder to that spot,the big pionts on the chip are extreemly easy to solder to practice on something alot smaller.

**K3N[ShadyLTD]** · 05-26-2005,07:05 PM

Thanks for explaining how to use the flux.

I scanned the modchip with my printer, i dont have a digital camera. This is what i did, I took a tiny bit of solder and made it into a a circular shape with the iron solder. Then i used the iron solder (with solder substane on it) and placed it on the part of the duo2 chip i was supposed to. I did this for all the neccessary points on the duo chip..

Took me over an hour and 20 minutes. Does this mean i must resolder everything so that the texture should have a reflecting effect, to prevent any short circuit?

I'll practice some more soldering tommorrow (connecting wires from one point to another). Right now im really exhausted...

You didnt follow my instructions from earlyer on

,you dont place solder onto something you solder directly to it,take the solder wire,dont brake it or re shape it,it is in the perfect form for soldering,slowly push some onto the soldering iron tip,it will melt and make the tip slightly wet with the liquid solder,dont add enay more,take the soldering wire and place it ontop of the solder pad(the duox) take the soldering iron and place it next to the solder wire on the pad,slowly feed some more wire onto the pad untill it melts against the soldering iron and fills the pad with the liqued solder,lift the soldering iron,and you are done.

BTW Your not ready to solder directly to your chip,find a old broken pcb and solder to that.
