28 more companies were named at least once. Companies outside the top ten are counted in the averages but not named here.

Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Illinois. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

  1. 1“Best electronic contract manufacturing and PCB assembly companies in Illinois”
  2. 2“Who supplies turnkey surface-mount PCB assembly for low-to-mid volume production in Illinois”
  3. 3“I need a Illinois electronic contract manufacturing partner for a 5,000-unit IoT device launch, who should I talk to”
  4. 4“Top electronic contract manufacturing and PCB assembly suppliers in Illinois for OEM electronics buyers”
  5. 5“Which Illinois electronic contract manufacturers can handle fine-pitch BGA and QFN PCB assembly with functional testing”
  6. 6“List 20 electronic contract manufacturing and PCB assembly companies in Illinois with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
