FACTORY
Electronics first. Then the pack.
The Shenzhen floor is an electronics plant: placement, assembly and test. Battery programs use that discipline.

Published equipment on the floor includes 140 high-precision placement machines, 50 automatic welding stations and 4 intelligent component towers. A battery quotation names the checks for that model. It does not borrow a certificate from another product.
