Panelized vs Individual Device Testing

Individual testing checks one board per fixture cycle. Panelized (parallel) testing checks several boards at once in a single fixture. Individual testing keeps fixtures simple, debugging fast, and upfront cost low. Panelized testing raises fixture complexity and cost but cuts per-unit test time — roughly 65–70% on a 4-up panel — once volumes justify it.

Start with individual testing and move to panelized once monthly volume passes roughly 1,000 units and the board design has stabilized. Keep an individual-test station for debugging and new-product bring-up even after you panelize.
