Stuck on the production of advanced circuits

[ArlenKnox]

Hi, I spent the afternoon reorganizing my advanced circuit production section. I set up three assemblies aligned as in a plan I had seen, thinking it would double my production. In reality, it created a huge bottleneck at the conveyors arriving at the assemblies, and some machines remain half idle. I think this is mainly due to the limited space on the board and the fact that I tried to squeeze everything together to save space. I've tried several rotations and rearrangements, but nothing works. I'm not a pro, just a player trying to optimize. Have you ever had this kind of problem and found solutions that work without having to dismantle everything?

Maybe you could show us pictures of what you're using right now? Then we might be able to suggest concrete improvements.

I usually end up having a second feeder belt join farther up the line to get more copper cables to the red assemblers, since that's the highest draw item.
Faster belts (blue/green) help.

If you're in Space Age, you will probably end up subbing in some direct-feed from foundries to electronics plants.
