Raspberry Soldering the Headers


First, get everything you need to solder the headers: a soldering iron, some solder, a cleaning sponge, a stand, two 20-pin headers, a breadboard, and of course, your Pico.

For easy soldering, we can use a breadboard to fix the two 20-pin headers first. With the black plastic block on the headers as the boundary, slowly insert the long end of the headers into the breadboard. When inserting, make sure that the two headers are aligned up and down, and spaced the same width as Pico.

Then, turn your Pico right side up and make sure the reserved pinholes on the PCB board are aligned with the headers that are fixed on the breadboard. After alignment, slowly insert the two headers into the reserved hole of Pico, and keep pushing until the black plastic block on the headers are sandwiched between your Pico and your breadboard. At this time, you'll see a small length of each pin sticking up out of the reserved pinholes on the PCB board.

Put your soldering iron in its stand, and turn on the switch to heat it. It will take 3–5 minutes for the tip of the iron to get hot. Make sure the metal tip isn't resting up against anything when heating.During heating, dampen your cleaning sponge first and put it in a convenient place for clean the iron later.

After heating, pick up your soldering iron by the handle, brush the metal tip repeatedly on the sponge you prepared until the tip looks shiny and clean.

Attention! The metal parts of soldering iron are very, very hot. Under no circumstances should you ever touch the metal parts of a soldering iron.

After cleaning, use the tip of the soldering iron to heat the pin and the gold-colored pad beneath it closest to you. Pick up some solder with the other hand, and slowly push it from the opposite direction of the soldering iron into the joint of the pin and the pad. The heated pin and pad melt the solder and make it flow around the pad. After completing the soldering in one direction, continue to push the solder in other directions until the pad is completely covered by the solder.

Attention! Do not use too much solder when soldering. If the solder overflows to adjacent pads, a short circuit will occur later when using the Pico.

Well, congratulations on your soldering of the first pin! Now, you just need to solder the remaining 39 pins in the same way. When soldering, remember to wipe your iron with a clean sponge from time to time to keep the tip clean and shiny.

After soldering, slowly pull Pico out of the breadboard. If the pins and the breadboard are plugged too tightly, forcibly pulling Pico out will easily cause the pads to fall off. If this happens, you can shake Pico from side to side, and try to move Pico out bit by bit.All right, we're done! Let's get started on our first task!
