Copper Wire to Green Circuit - Why can't I solve this bottleneck?

[Fugazi123]

New to the game. I don't pay much attention to ratios yet, I mostly just expand as needed when bottlenecks form.

I have a green circuit bottleneck but can't figure out why I can't get the copper wire to the green circuit assemblers fast enough. I'm using fast belts between the wires and circuits. Half of the copper wire assemblers are backed up at the output, and half of the green circuit assemblers aren't getting enough input.

What is the obvious solution I'm missing here?

feeding the copper wire directly in the green chip assembler

A screenshot would be nice.

But i assume you need to extend your production of copper wire. You need three copper wire for one electronic circuit (green circuit).

You are bottlenecked by the belts - you can see this by looking at where they become empty/full (or almost so). 10 assembling machine 2s making copper wire continuously can completely empty a transport belt of copper and fill a fast transport belt of copper wire. A full fast transport belt of copper wire is only enough to keep 6 2/3 assenbling machine 2s making electronic circuits continuously.

With assembling machines that consume and/or produce items at a high rate such as when making electronic circuits, inserters are another potential bottleneck. For example, a single basic (yellow) or long-handed inserter can't insert iron plate or remove electronic circuits fast enough for an assembling machine 2 to make electronic circuits continuously, unless you have researched Inserter capacity bonus 2. Assuming available input items or output space, the result is inserters continuously active while assembling machines are not (missing items or output full at times), but this is more difficult to spot.

Also keep in mind that one copper plate turns into two copper cables. Combined with the very fast production time of green circuits (0.5s), and them needing three cables per craft, that makes it a really bad idea to belt the cables in this case. As shown above direct insertion is the solution here.

This isn't the case for red circuits later. Their production time is quite high at 6 seconds, and so a single cable assembler can comfortably supply a good number of circuit assembler using just half a lane of belt.
