This is a board for electronics workshops where students learn to solder. It has 8 'levels' with increasing difficulty. The first 4 levels are through-hole and the last 4 are SMD with decreasing size down to 0603 components.
This board can also be used for soldering competitions by giving the competitors a certain amount of time (e.g. 15 minutes). Whoever has the most points wins. You can also give a bonus point for least amount of solder used and nicest solder joints to make it a maximum of 10 points.
- 5x10cm 2-layer board that can be made by every dirt cheap chinese board manufacturer for 10-20$ per 10pcs
- Only one value for every footprint (e.g. all 0603 resistors are of the same value) to prevent errors from misplaced components
- Built-in point display. After soldering the teacher touches a 9V battery to a pad and the number of points (0 to 8) are displayed via LEDs.
- Uses only low cost components that are available at many distributors. At 1000 pieces the bom is about $1.50
- The board has rubber bumpers on the bottom so no PCB holding device is needed.
- Reverse polarity protection.

This is what a soldering competition looks like - can you beat 17minutes and 21 seconds?
