Breadboarding
Breadboarding is the practice of building solderless prototype circuits on a perforated board, used early in battery pack design to validate sensor wiring, BMS protection schemes, or charging controllers before committing to a PCB. As a hard skill it requires the discipline to organize component placement so the circuit is debuggable, to use proper grounding and decoupling on a breadboard's noisy power rails, and to translate a working breadboard into a manufacturable layout. Engineers apply it during BMS algorithm bring-up, when iterating an electrolyte-fill sensor circuit, or when testing a new cell-monitoring IC before committing to a board spin.
