Hey what's up everyone. I'm 17 and I want to take on the challenge of building this RF Jammer. I can do simple stuff like build a computer etc. but I have never soldered a circuit board.
I know it's a tough task , so laugh , but I want to accomplish this. Do you guys think I can do it? Either way I will try to make it , and then upload the picture of it ( or video ) when I am finished , maybe even give you guys a laugh if it turns out bad ( or doesn't turn out ).
I will start buying the materials in a couple of weeks when I have more time , but will be studying a little bit until then. Have you guys made any big mistakes that I should look out for and avoid?

Fiind a thrift store and get junk electronics with SMD parts in them. The DSS boxes are usually pretty cheap and are in the same skill level as this project.
Use a heat gun to strip the board. Heat it from the back and slam it on the bench or scrape the parts off of it while hot, then put them back.
There are more elegant ways to salvage parts but you are going to destroy these anyway dont fret damaging them at first. Learn to salvage after you learn to build.

This project is challenging and at the same time rewarding . The most difficult part IS the soldering! Not that soldering is a difficult task, it's the small size of components being soldered that poses the greatest challenge. The 1206 (3.2 mm × 1.6 mm) and larger parts aren't that bad, it's the 0603 (1.6 mm × 0.8 mm) and IC's with 0.65mm pin pitch that test your skills. I would recommend getting an iron with the smallest tip you can (I used a 1mm angled tip). Rosin flux will also help greatly with solder flow on the IC pins. Since you have never soldered I would buy extras of all your parts

Could anyone please comment these videos?
I didn't try it that way but it looks nice!

You could put more than one on the board and solder all parts at a time...
I think I'll get a hot-air solder.

I looked into it but the paste is expensive and has a limited shelf life. I believe it also has to be kept refrigerated until use and, as such, requires overnight shipping. If you're not careful you will burn up the board or part using hot air. Don't get me wrong, I have a hot air gun and love it. I use it primarily for component removal. I relied on traditional hand soldering for my WB.

Guru is correct the paste is expensive and requires refrigeration. Also it has a short shelf life.
Remember that as you are learning the hot air or oven method with solder paste you are going to use too much or too little solder paste and will have to fix things with an iron. So you have to learn the iron skills anyway. Cleaning up with solder wick is easier than it looks!
Start with the iron it is a skill you will always need. The other methods are fast as you get good at them but also require practice, with the iron you ruin one part at a time. With the other methods you ruin the whole thing (with hot air you can ruin the board very easily!!!) at one time. Just something to think about.
Edited to add: If you want to use the heat gun try salvaging first, might be surprised how hot you can get things with one.

Try this link for solder paste. I just got some and am pretty happy with it. Refrigeration of this solder paste is optional and unless its roasting hot outside, should survive shipping time without a problem. The kit is ~$25 and has many syringe tips for different pads. Also checkout sparkfun.com for different soldering techniques, like toaster oven, and hotplate... yes, for real!

I recommend this approach to SMT work: http://youtube.com/watch?v=4V7tBPsECjc
This is the technique that I learned from a little girl on the assembly line in China. She had mad soldering iron skillz, yo. It was actually quite a treat to watch her and her colleagues work. They could get ICs off a board in good enough shape to re-use that I would have to scrap to remove.
Simple and effective. Forget all that solder paste and hot air jazz, this is an easy way that works really well.
