In Sonora, we’ve started mapping our supplier base — documenting who’s out there, what they offer, and how they might connect to semiconductor value chains.

But mapping is only a starting point.

If the goal is to support outsourced assembly, test, and packaging (ATP) operations, supplier visibility needs to go deeper — and last longer.

It needs to move from a static list to something dynamic and useful. It needs to become infrastructure.

One of the most dangerous assumptions in supply chain planning is that the parts you need will be there when you need them. That someone, somewhere, is already making them. That all the tools and materials you’ll need to run a backend line — substrates, thermal compounds, packaging kits — are just one purchase order away.
