    Hi

    Here's a 13 minute video showing me soldering those little 5mmx5mm RGB SMD LED's that i am using for my megatre and that many people have purchased recently in a coop at DIYC

    In the video i solder 7 LED's in series to make a RGB section that will eventually become part of a longer string.

    The wire/cable used is 28AWG ribbon cable, the spacing of the conductors being close to the spacing on the solder pads on the LED's. Close being the operative word.

    I would normally lay 28 of them out at a time and solder 4 sections.

    Soldering PLCC6-5050 RGB LEDS

    Cheers
    Phil

    Greetings,,,

    Nice show. Makes it look easy. :D

    Like the way to bend the cable to hold the leds outward.

    Looks Good :D. Hoping to take your example and do my LED's when they get in from the Coop. Need to get with you to get a controller to go with the strings.

    Just curious how many joints do you average with the 10 cc syringe of solder paste?

    The original solder paste i was using for the led's was a couple of years old and it was a chance to use it up, not sure how much was left or what i used but it did around 2000 leds.

    I'm expecting around the same number from a new 10cc..

    Cheers

    Alec,

    I have done it both ways, with normal solder and paste, for me paste is faster and that is important for the quantity i have to do.
    It tends to be a bit messy when it splatters but still faster.

    Cheers
    Phil

    Great stuff Phil, I just may eventually have a go at doing that myself one day. Looks like that's the way its all heading anyway, so might as well start learning and having a go at SMD soldering

    The camera was not zoomed at all from memory but it has only about 300mm away though :)

    I use a 3x diopter magnifier all the time these days working with small parts.

    Cheers

    Fab video ... and for a moment, I thought that looks easy (btw, it does)! That was until I tried to buy some stuff ... blue tac (check), solder station (not a good one ... but check), paste (no go), 28AWG ribbon cable (no go) ... and obviously, I don't have the LEDs ... lol

    However, my realisation, after watching the vid several times, is that even if I had everything in front of me I do not know how to tin anything ... so my question becomes, could you supply a vid on the tinning aspect of the 28AWG ribbon cable, pls?

    Hope this helps you out..

    Thanks Randy and Phil ... now, I understand!

    Questions:

    Q1 Where do you buy the 28AWG ribbon cable locally?

    Q2 By the looks of the cable, is it the same as the old ide/fdd cables? If so, I have found some to practise on :D

    Spot on - same as floppy drive and old 40 wire IDE cables.
