This rather compact factory produces 360 advanced (red) circuits per minute.
It takes in 720 plastic per minute (<1 yellow belt), 1,800 copper plates per minute (1 red belt) and 720 iron plates per minute (<1 yellow belt).
The ratios of assemblers are optimized to within about 2 extra copper wire assemblers.
The red belts are kept to a minimum but are unavoidable in such a compact design.
(I used Bob's Adjustable Inserters in the old version of the screenshot. In a new version they were replaced with priority splitters.)
- Place the blueprint and connect it to power.
- Feed in the required materials:
- Left belt: Plastic (720 per minute)
- Center belt: Copper plates (1,800 per minute)
- Right belt: Iron plates (720 per minute)
