Led soldering tutorial.....Use as a guide at your own risk.

[NDredsox]

Ok, since I received help in the matter, I figured I would give back to the "community". This turtorial was made in about 20 minutes(not including the photoshoping) and is meant to be a basis for your modding needs. I once again will say, DO AT YOUR OWN RISK!


Lets begin with the tools that you will need. This is just what I use and it seems to work the best out of any other tools I have used. They are all available online, or from Radio Shack and Sears.

1 - Soldering iron - I use the 15 watt iron with fine tip from RS. I buy the tip and then turn it on and let it heat up and then unplug it and then repeat till full heat. Once fully hot, I coat it with solder and then turn it off and let the solder dry on it. Let it sit for a few minutes to fully harden and then you are ready to go.

2 - Tweezers - nuff said

3 - Pin - some people file them down, but I don't.

4 - Torx screwdriver - I use the husky version available at your local home SPAMSPAMSPAMSPAMSPAM for like 6 bux. (if you ask what a torx driver is, quit reading and goto Jeff's tutorial on how to take the phone apart)

5 - Solder - I use .022 diamter from radio shack.
http://home.comcast.net/~kheimbuch/solder/2.JPG

6 - Desoldering Braid - From rs also.
http://home.comcast.net/~kheimbuch/solder/3.JPG

7 - Solder weld - for beginners it works great. Its a paste that when heat is applied, it turns hard. Package says harder than regular solder.
http://home.comcast.net/~kheimbuch/solder/4.JPG

8 - Craftsman Liquid Rosin flux - Helps draw excess solder from the KP.
http://home.comcast.net/~kheimbuch/solder/7.JPG

9 - Soldering work station - Available for about 6 bux from rs and is a great tool. Holds your iron and also has a sponge to clean off the tip after solders.
http://home.comcast.net/~kheimbuch/solder/1.JPG

10 - Insulated wire - I use 30 gauge, some people use 37 gauge. For vents mods and putting leds where ever you want to put them.

Now to the fun part.

First turn the iron on and wet your sponge from the work station. I am using an old old i60 board for this that I learned on. So disregard the melted kp...lol

Ok, I dip my Q-Tip into the flux.
http://home.comcast.net/~kheimbuch/solder/8.JPG

Then I apply the flux to the led and resistor on the boards.
http://home.comcast.net/~kheimbuch/solder/9.JPG

Then I use the desoldering braid and lay it on the led.
http://home.comcast.net/~kheimbuch/solder/10.JPG

Then apply heat to the top of the braid, I lay it right on the braid, and soon the solder will start to pull from the led. This is the first part of removal.
http://home.comcast.net/~kheimbuch/solder/11.JPG

Next,
Get your pin and place it under the led.
http://home.comcast.net/~kheimbuch/solder/12.JPG

Heat up the leftover solder while prying the led up slightly. IMPORTANT: don't apply too much pressure or you will rip the solder points off of the board.
http://home.comcast.net/~kheimbuch/solder/13.JPG

Then switch to the other side and repeat until the led/resistor is free.
http://home.comcast.net/~kheimbuch/solder/14.JPG

Then you will have solder points visible and the led/resistor is gone.
http://home.comcast.net/~kheimbuch/solder/15.JPG

Once the led is free, I put flux on the solder points again and allow it to dry fully.
http://home.comcast.net/~kheimbuch/solder/16.JPG

Then I lay the desolder braid on top and pull the excess solder off.
http://home.comcast.net/~kheimbuch/solder/17.JPG

Your solder points should look like this.
http://home.comcast.net/~kheimbuch/solder/18.JPG

[NDredsox]

NOW,
Grab your led with your tweezers and line it up where you want it to go.
http://home.comcast.net/~kheimbuch/solder/19.JPG

I use the tweezers in my left hand and the iron in my right, but since I don't have three hands I left out the tweezers in the pic and just layed the led on the board
http://home.comcast.net/~kheimbuch/solder/20.JPG

Then apply heat with solder on your iron to each side
http://home.comcast.net/~kheimbuch/solder/21.JPG

http://home.comcast.net/~kheimbuch/solder/22.JPG

Let it dry completely before checkin the Led for light with the battery and thats all there is to it!!!!

If taking off your status light, just do it the same way as above as far as taking it off.

http://home.comcast.net/~kheimbuch/solder/sl2.JPG

[NDredsox]

If you are wanting to add leds to the vents or Ptt/Home buttons, this is what I do. Same if you are adding dual status.

I always add solder to my iron and then lay the wire near the led and heat both up and remove heat source and waalaa.
http://home.comcast.net/~kheimbuch/solder/24.JPG
http://home.comcast.net/~kheimbuch/solder/26.JPG

Lay your 30 gauge wire on the solder point that you wish to use and add solder from the iron to make the joint.
http://home.comcast.net/~kheimbuch/solder/23.JPG

Then I connect the wire to the other side of the led and solder it together.
http://home.comcast.net/~kheimbuch/solder/25.JPG
http://home.comcast.net/~kheimbuch/solder/27.JPG

Lastly, solder the other wire to the solder point to complete the circuit and apply solder and you are all set.

Use these diagrams to determine your correct side for solder and dual status diagram for that.

Xcellent X, this is the bomb. :up:

[NDredsox]

Thanks, if I left out anything, or if anyone has questions, I will try to answer them. Thakns

[XsTrEeTfLyErX]

You are a SPAMSPAMSPAMSPAMing god my friend. i think my iron is too hot though its butain and i have it on as low as possible but i keep ripping off the solder points

[NDredsox]

You are a fudgen god my friend. i think my iron is too hot though its butain and i have it on as low as possible but i keep ripping off the solder points

Either too hot or you are forcing them off too quick. 7 bux or so gets ya a 15 watt iron from radio shack and should do the trick. I also play around with putting a whole bunch of solder on my iron and cover the entire led. Then let it dry and then heat the "glob" up and then push slightly and it comes off that way too. Then use the braid to get the excess solder off.

Good luck man!

[purrfectlyruth]

Hmmm, gonna try this...wait..do I dare?!?!?!?!

:thinking:

[Nextel Boy]

Yo this is such a good tutorial i think it should only be available to people that have donated : )

[NDredsox]

Well thanks man(boy), I was thinking the same thing, but all of the info is out there, I just did the work of combining it. Plus I am sure its on someone elses site w/o permisssion or on somebodys ebay disc already. Oh well no biggie. :king:

[crazysim]

does it matter what size solder you use?
cuz on the radioshack website the closet one i saw was .032 diameter is that good?

[NDredsox]

yeah that will work. I should have some irons in here in the next few days......if anyone needs them, i will send out 10 bux shipped and they are like the ones that i use. I will have 12 of them.

[crazysim]

would have ne extra solder for sale :mrgreen:

[NDredsox]

Sure, I Have some.....Rosin Core Solder - 0.32", 2.5 oz. = 9 bux shipped.

[Nextel Boy]

Hey guess what i got the balls and im going out next week to buy all the stuff : ) i9 will post pics asap of my i90 : ) also can u put up a mod for changing the i60 and i90 screen color useing leds : ) i know the way but i think u should post it : ) :up:

[crazysim]

only if i read it a lil before i just spend my money and i gave the rest to the site

[NDredsox]

If you know how, go ahead and post it. I don't see myself having time for a week or so.

[Nextel Boy]

ok. What about the screens i heard u cna put leds under the screens to change the colors,the i60 is easy but the i90 has to be done custom?

[NDredsox]

Your Quote "i know the way but i think u should post it : )"

I thought you knew. lol

Check WCO for pics of the i90 lcd color change. :king:

[Nextel Boy]

lol i do know i just dont have a i90 screen to post pics and explain :wink:

[NDredsox]

Leds for an i830?? anyone?? :king:

big pic for detail

[Jimbo]

cant wait! looks fun

[NDredsox]

830 leds are a bitch!!!

[purrfectlyruth]

I can't beleive you opened it up already!!!! LOL :lol:

[NDredsox]

Couldn't resist. :king:

[Partsman]

ah, thats easy :jo:

[NDredsox]

Finally finished the leds....Hyper White. They are a pain to do.

[BrIaNbLuNt]

thas hot shit thereee , can u mod the LCD to white 2

[NDredsox]

Yeah....I think. I need to take it apart tonight and see how the leds are laid out. I wonder if the disco lights emit the blue leds or if it is another set of leds.

[Mynzeyes]

ok...um...what kind of LEDs do the phones use? more specifically, the i95, i730, and i830...i can't seem to find a number or type anywhere...

thanks in advance,
-John-

not to thread crap but i was wondering the same thing and seen he never got a response. So any info would be great thanks

[crazysim]

are the LED's for the CID screen a different size LED because the LED thats there is bigger

[Jimbo]

they are 0603 profile SMT LEDs

[mebe]

they are 0603 profile SMT LEDs

so are the resistors the 681 or 301's. Also cant you take the flashing chips off of like the ribbons of led inserts to do the flashing in like the flip area??
Thanks so much also :up: :up:

[Jimbo]

resistors are 681. i would imagine u would be able to use the rf chip to do a flip mod

[cuz123]

first off where can i get some flux rs doesn't have none. can u explain how the whole resistor thing works and wheredo they go and why do u need them. i know everything else. thanks :beer: :beer: :beer:

[NDredsox]

You can buy flux from RS online, resistors are needed for the blank spots if you add leds, there is a diagram on the first page on where they go.

[cuz123]

so when u remove a led thats already there u don't need a resistor???

[NDredsox]

As long as you don't remove the resistor also, it will still be there. No need for another one.

[cuz123]

where do u guys get leds from????

[NDredsox]

Online, Ebay, google "smt leds" and it will show up.

[cuz123]

been trying to do this but i can't see the points that the led is connected too.

[cuz123]

yo radioshack online does not have flux. :down:

[NDredsox]

yo radioshack online does not have flux. :down:


THEY DON'T??????!!!!!!

Take some time and search.

Edit is the word of the day, not double post.

[cuz123]

my bad i thought we needed liquid flux like it said in the tutorial thanks alot for clearing it up. :up: :up: :up:

[cuz123]

when u put a led on u got to match postive with postive right.

[Partsman]

Edit is the word of the day, not double post.

^ ^^ uhhh, EDIT your posts please. don't double post or jimbo will ban you. :twisted: ^ ^^

[Jimbo]

:neutral:

[NDredsox]

Jimbo is a man Mutha-shut your mouth!! I'm just talkin bout Jim. :dj:

[brewmaster]

what would u guys suggest using for a type of glue like is there some special kind or something. i just need it to hold the leds and the wires down to the circuit bored

[NDredsox]

Hot glue or model glue.

[landonnin1]

fir adding led to the board where there are 2 onpen places on the i730, if you wanted to solder wire in one of the places on the board so you can put the leds in another location can you ru 2 led from one solder point on the board and one resistor ?

[Billyjr]

either im too young to do this.,,,or ima sped cuase i cant figure out how...i cant get the led off any tips?...also which iron should i use...i have a butane...or i have the cold heat...

[Trogdor]

How about the CI on a i95? anyone have any tips? Theres a chunk of plastic from the LCD that covers the leds, and I'm alittle uncomfortable about just bending the ribbon.

[ratherbewalking]

i found it a little rough as well, i suggest a captain and coke, and then get to it.

Seriously though, my suggestion would be, just take your time, and dont crease it. good luck
