soldering RGB 0603 LED SMD on a breadboard ?

Other Hardware General Electronics
1

Good day all,

I found a bi-color LED SMD 0603 that I will be using for my project (led chaser on a custom PCB).

Said LED have 4 connections: 2 ground, and one for the blue and one for the orange.
Obviously I will need to connect each color of the LED (orange and blue) to one individual pin of my atmega328p-au.

My issue:

The LED will be soldered the same way shown in the picture attached to this post (facing the user, not facing the upper direction) so how do i connect each color of the led to a pin of my atmega knowing one of the led connection will be up without anyway to connect it ?

thanks.

Obviously the LED is different to that shown on your example picture. Since it is on the board edge, you have the actual edge of the double-sided PCB rebated to fit the LED in on its side, with the solder pads on each side brought to that rebated edge so that two pads on each side match two of the pads on the LED.

You do have some current limiting resistors, don't you?

So basicaly your idea is to bend the PCB ?

Yes of course.

LEDs are easily destroyed by improper soldering techniques. Did you see the maximum time and temp in the data sheet? Hand Soldering : 350

Hardly! :grinning:

You mount the LEDs on the very edge of the PCB so that the lands on one side of the LED solder to the tracks on one side and the lands on the other side of the LED solder to the tracks on the other side.

And yes, you can get thin flexible PCBs - very commonly used for many years now in printers, disc and CD drives.
