Which semiconductor manufacturers have large factories there? What consumer electronics products are manufactured there? What is the size of the largest factory and where is it?
Intel has in Costa Rica. As one point, all Intel first generation i3, i5, and i7 CPUs came from Costa Rica. Also, all Intel motherboards came from Costa Rica. Get a sense how big it is? The site is still active but switched to other electronic component production.
Car part manufacturers for LED and driver controller PCB boards have facilities in Honduras (Lear and Empire Electronics). Those companies already employ 20k people in total. That's for Ford, GM and Chrysler.
Brazil has component assembly facilities for several companies, not sure how big as I don't have the details.
I can go on and on....
