Alternative to Soldering 0402 SMD LEDs

Alternative to Soldering 0402 SMD LEDs

This video provides an alternative method to soldering or wiring low voltage, small electronic parts like 0603 or 0402 LEDs. Conductive glues or adhesives (called liquid solder by old-timers) can be used instead of heat soldering. Some criticize the use of conductive glue as opposed to soldering as if their use is an immature approach or only used when soldering skills are lacking. However, conductive glues are tools of sort, and like all tools, conductive glues have their own place.
Conductive glues are an acceptable method to make conductive connections in situations where heat is not appreciated nor tolerable such as near plastics, detriment to wire sheathing and/or other heat sensitive materials.
The manufacture of conductive adhesives is a billion dollar industry, involving numerous chemically based conductive compounds. Some of the most highly conductive compounds are extremely expensive such as aluminum epoxy, nickel epoxy, silver epoxy, up to gold epoxy.
The conductive...

    Thank you for this video.  Very good idea.  I am working on a small strip of 8 0603's following the exact method.  Although the wire glue is still setting, I am using a 12v pwr supply with 470 ohm resistor.  There seems to be some inconsistency with brightness, hopefully this is just quality control issues with the LED's but I made sure to use a good amount of wire glue to have a solid conductivity.  Hopefully when it dries fully it will improve

    Good video! I may try this for some custom model circuits so I don't have to solder it. My soldering skills are very novice and I have a hard time with getting circuit boards done right
