Snow Flake Component Side

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.

Snow Flake Assembly Video

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.

Perfect Snow Flake Panels from Eurocircuits

Eurocircuits delivered some perfect panels for the snow flake board. Each panel has five snow flake boards on it. This was an impressive good job from from Eurocircuits. There are a quite number of challenges to produce panels in this outstanding quality: The width of the small decorative lines on the front is just 0.15mm. […]
