Dude that's an assembly line for individual Avalon unit manufacture, Yifu hasn't gone out and purchased his own semiconductor foundry, that would be nuts!!!
Yeah I know, but if they are still doing the production of their own modules, they need a lot of these chips. That is, they must have good and stable source of them (or their own production line).
Exact same as they expect their customers to do. They have to order a volume batch themselves; either 100,000s or 1,000,000. May even be less as NRE is complete and the foundry will have the order on file, but it's unlikely to be per 10k...
