surface mount soldering video

[Admin]

found two videos of surface mount soldering today. me being someone who only fails when doing surface mounts, i thought i should share these . . .

the first one uses some technique ive never seen before with an IC. can someone tell me exactly what he is doing with that soldering wick looking thing?

the other is soldering of a transistor (the video is kind of choppy). it looks like he placed some solder onto the board already, then melted it when the transistor was placed onto the board.

this seems to explain the wick method better:

and one more video for the fun of it

i also heard of this method where one puts some type of solder paste onto the board, lays all the components out on to the board, then puts the whole board into an oven for a bit. anyone know more about this?

found this from your link (interesting!)

Hey, my tutor seems to swear by the method of putting loads and loads of solder on, then whacking it against a table to clean it up.

It works all the time.......for him at least.

A few days ago I was in a collegiate electronics competition and there was a portion on soldering. One of the components was SMT. I had never soldered a SMT component, but I tried what I saw on that video and it worked perfectly. The 1st time! BTW I won the competition too. Thanks John!

BTW I won the competition too. Thanks John!sweet! which competition?

[Joe]

It's called SkillsUSA. It's kind of a vocational-oreinted competition. My particular competition was the "Electronics Technology" category and involved breadboarding, troubleshooting and soldering. It's not the biggest deal in the world but it's something for the ol' resume.

Another surface mount tutorial. Shows how to do IC's that have 100's of fine pitch pins all in one go:

a method to make a cheap ($20) reflow iron (normally $100's):

by far the best surface mount video tutorial I've seen:

Its called a reflow oven. Its how most boards are built in professional manufacture.
The board is made, solder paste is spread over a template on top of the board(the template has the solder pads cut out). The template is removed leaving solder paste on the pads. The components arepicked up and placed into position with robotic arms. The whole board goes into a reflow oven where the solder paste magically sticks it all together. Most datasheets will give a temperature that components can withstand for reflowing

yes. this is called tinning and is really useful if the component/whatever you want to solder on has to be held in place by you. All you do is get some solder onto the connection that you are soldering onto, then place the component on the solder and heat it up
