Nintendo Switch a new problem - Won't power on or charge 

Yes. The smile. I know from personal experience that it is SO satisfying when the problem is found and corrected. A strangely fulfilling emotion.

Awesome Alex, Big Boss… I wish y’all would open business out here in Anchorage Alaska so I’d like work with y’all to get myself learn faster then work like your job out here to help all customers device and make them happy bring home get their device to using, :)

you are forgetting the hot tweezers ;-)

Same here ^^ Tu es toi même réparateur ?

@@hawk2798 non. Je fais juste pour moi.

Nice question. Can someone answer?

For me, it's just experience and knowing your tools and technique combination. Pads are thin and take little heat to get solder attached but it's how many pads in the area to re-tin versus the amount of solder needed to cover them. Get some old boards and remove the components and then remove the old solder using copper mesh, alcohol clean the area and reflux, then use only your solder iron with the different tips to get the feel for how much heat and solder you need to re-tin the pads. REPETITION is how you learn. I use a combination of techniques for big chip removal and replacement such as bending copper wire into the outer shape of the chip's feet to heat them all up at once. Usually there is enough heat from using this technique that will also melt the solder under the chip. It's a great technique for when a heat gun will be too close to something that will melt. And always make sure that you are venting your solder gases away. Even if you have to set up a box fan in a window blowing out, that will keep the solder gases from being breathed. I use a bar of salammoniac to keep my solder tips clean along with a stainless steel scrub pad. Sometimes if the board I'm working on is dirty I will have a wet cotton towel near by to wipe my solder tip on. Clean solder tip, flux and heat setting all takes experience to control as well as how much solder to keep melting on the tip. I used to do a lot of copper work on chimney flashings using a 50/50 tin/lead bar and large soldering coppers that I heated using a propane fired oven. The flux I used was called "cherry juice" as it was redish pink in color. Occasionally I would also solder galvanized sheet metal that I first had to brush on hydrochloric acid in the areas I was soldering to break down the zinc coating so that I could make the tin/lead solder stick. I used the same soldering technique there that I use in my micro soldering. My first micro soldering gun was a Sears electric solder gun that I used with electrical acid core solder. Electronic soldering gear has come a long way since then.

It's simply a better technique

It helps you have better control over the amount of solder that you apply to the pads, and it is also better for small areas where you only have the soldering tip in there, as opposed to the soldering tip + the solder wire, which you need two hands to do and blocks your view more

Honestly you can do it either way. Alex is just showing multiple ways to do the same thing. For some people one way is easier than another. So in the end it's all about what you feel comfortable doing.

Good catch. Best earphones I've used.

His experience tells him it's usually the chips...but you learn something new every day!

Thats what i was thinking haha

@@andrzejzielinski7871 yea, thats probably the most efficient way

Get the Chocolat of course

It's this same problem. I have it too.

Well im not a soldering pro but from what i understant is it makes the solder stick only to metals. After soldering the chip he also uses it to remove any bridges between the pins. Also very important is that solder prevents oxidation. At first i also didnt understand why the solder is used but thanks the videos like this now i see how it would be almost impossible to do certain soldering projects especially microsoldering. Im not talking about soldering together two wires, thats very basic level of soldering.

flux help flow of solder, watch some of his videos and you'll understand
