ICT (In-Circuit Testing) is a way to check if electronic circuit boards are built correctly during manufacturing. Think of it like a health check-up for electronics - special machines use tiny pins to touch different parts of a circuit board to make sure everything is working properly. This testing happens before the final product (like a computer or phone) is assembled. It helps catch problems early, saving time and money by finding defective boards before they go into finished products. Other names for this process include "bed of nails testing" or "automated circuit testing."
