Today I show you a little bit longer video about the assembly of the component side of the snow flake panel.
Compared with the very small 0402 LEDs (1mm x 0.5mm) on the front side, the component side contains just regular 0805 resistors and capacitors.
The first part of the video shows how I apply the solder paste using a metal stencil. I use a system called “eC-stencil-fix” from Eurocircuits. This is basically a set of plates with metal knobs to perfectly align the board with the stencil. With a tick in a checkbox, they produce panels which perfectly work using this stencil fix system, which is really convenient.

Here a quick video of the snow flake assembly. It shows the assembly of the LED side of the panel using hot air.
The assembly went without big problems, except there was a little bit excess solder on the pads. Therefore the LEDs do not lay perfectly flat on the board.
For the Boldport Club project “The Matrix” I used hot air soldering for the first time. After some experimenting and with help from Boldport Club members, it worked really well. I could colder the 120 LEDs in less than 10 minutes to the board.
I made a video about the process. Please keep in mind, I am new with this process, so this is absolutely no instruction video how things should be done. I may be absolutely wrong. 😀 Enjoy!
Here a list of the objects and tools you can see in the video:
