Soldering

When soldering your Skintimacy, you can choose between following the instructions showed in the gallery below, or go in detail through each step scrolling down the page.

INSTRUCTIONS

STEP BY STEP

You start with the circuit board positioned as in the picture below. The „Skintimacy – v1.0“ lettering should be in your lower left corner.
0
You need four pin pairs. Connect each jumper to the longer side of a pin pair. Carefully use Scotch tape to keep the joined parts in its position and solder.

1.0 1.1
First, solder the mounts, then add the chips (U1 and U3) to the mounts. Important: Mind the dents on the chips for orientation!

2.0 2.1
Solder the film capacitors. The two 1uF ones have the lowest position (C1 and C6).

3.0 3.1
There are five different types of resistors. Don‘t worry about the orientation. It makes sense, though, to have parts of the same group facing the same direction.

4.0 4.1 4.2
4.3 4.4
Make sure the four transistors’ flat sides face the device’s middle. Don‘t mix up the U4 regulator with a similar looking transistor!

5.0 5.1 5.2
5.3 5.4 5.5
The long leg of each of the three capacitors must go into the hole marked with ”+” next to it. The diode‘s long leg goes into the square framed hole.

6.0 6.1 6.2
6.3 6.4 6.5
The short leg of each LED should be on the flat side of the circular mark.

7.0 7.1
7.2 7.3
