Ive actually used the same ones you did, and despite what the data sheet says, dont run them at 150mA! From what I was told, it’s made in Japan and soldiered by robot into these neat little buggers. 5 years ago, old post i know, but i liked it :) had to comment, 6 years ago Chip-on-board packaging (COB), where semiconductor chips are handed over and mounted on a printed circuit board. As I saw it, there's 2 was to handle it. Anyway, good luck with your project. Yes, there are some offered in different color temperatures of white, but why not, I already mentioned they are cheap. Copper Wires, I've used cat 3 solid core, these are rigid enough to hold its shape and thin enough so I can bend it easily into a tight configuration. Then used an xacto knife, cutting little squares, probably no more than 1/2 a millimeter long. :-), Reply Share it with us! I've also done an instructable on Soldering Through Hole Parts (THT) so check out that as well. Reply solder electric wires to COB LEDs, tips with high heat capacities should be used. Solder the wires to the copper dots one more time and wait for them to dry. Let the iron rest on the braid without additional pressure, to avoid pushing the solder pad out of place. 7 years ago Sorry about my negative comments but vibration and water are two big contributors to failed electrics in a car. Solder wick is critical for soldering larger parts. About 24% of these are Other Welding Equipment. Had a feeling it would eventually give, actually surprised how long it lasted considering I knew it was really hot to the touch. Testing, it lit up, as expected, but had no idea how well it will keep working. It's all good, no need to be sorry for offering your thoughts, and yes, did consider the vibration issue. Magnifying glass, helpful to be able to see these suckers. Right away, there was a problem. I don't have hot air reworking gear.The hardest part is to remove the old chip. The light distribution is probably the closest possible for any array of LEDs to approximate an incandescent 194 bulb. But I am surprised that part of the array is still working, I expected the whole thing to black out since all the LEDs are placed in series. Now for tinning the LEDs, I smashed a portion of the soldering wire flat, careful to not smash it too much because there is rosin flux in the wire. Basically it was meant to act like a spring and absorb the vibrations.Guess This is a good time for an update. • Precautions must be taken as mechanical stress on the LeDs may be caused by PCB warpage or from the clinching and cutting of the LeD leads. We will be learning to solder on all different components. on Introduction. I can sleep well experimenting with cheap stuff! Solder Joint Reliability of Bga, Csp, Flip Chip, and Fine Pitch Smt Assemblies (Electronic Packaging and Interconnection Series) JunYe 220V 301W LED Remover Heating Soldering Chip … I started this channel in order to inspire you to create. It simply shows how to solder a wire to the pin in real time, with text running over the video. The electrical connection between the chip and the substrate is achieved by a wire stitching method. Of course, just the nature of doing things by hand, there’s bound to be mistakes, de-soldering is way easier to do. Tinning soldering iron tip Tin the Tip: Trying to solder without a tinned tip is futile. Using flux is not mandatory here. Repeat the soldering for the second LED. Really! If they ever get a cavity or pock marks in them, that means it's time for another one. The one on the right is a well designed replacement for the 194 bulb. 1 year ago, I would suggest using some flux to get some better solder joints, Question I’m not exactly a fan of having attention grabbing illumination for my plates. A light touch of the tip of the soldering iron and presto, nice microscopic balls of tinned contacts. While holding it in place with the tweezers, you heat the tinned end until the solder melts and adheres to the chip. If you pot ( cast in resin) the PCB do not use a resin that sets rock hard and shrinks when cured as this can also break components or connections. This happened on both sides. To re-solder just dab the area with a little flux on the end of a needle and press with the iron until results are to your liking. 9 years ago The procedure for soldering waterproof LED strip is almost similar to that of soldering the simple strips except here you have to cut the epoxy sealant before applying to solder to the hard points of the strip. The tutorial opts out for more showing and less telling. Even an LDO chip, low dropout voltage regulator, or an LED on the board consumes extra current that would affect our measured results, let’s say of the ESP32 power consumption. This method is quite useful for soldering SOP IC. Not good, resistor are supposed to get hot, bringing down current by converting it to heat, but it was so hot, that I was afraid it will melt the solder, and fry the LEDs no less. Published time: 2019-12-24 11:50:41. The picture shows 2 different commercially available ones. Well, I simply didn’t like the color. on Introduction, Those Specific LED's Need to be heat sinked better. The next step is to wipe off the excess solder with a wet sponge and finally reapply a little amount of solder to the tip again. First was to tin the copper wires, this is easily done by holding the iron to the soldering wire and running the copper wire back and forth on the iron. For more details on the types of tips that might be useful for this purpose, refer to Table 1.
