QFN
QFN (Quad Flat No-leads) is a type of packaging used to protect and connect computer chips. Think of it like a tiny protective case that houses delicate electronic components. It's called "quad flat" because it's square-shaped and flat, and "no-leads" because it doesn't have the traditional metal legs sticking out that older chip packages had. This packaging style is popular because it takes up less space and can help electronic devices be smaller and thinner. When someone mentions QFN experience in their resume, they're typically talking about their work with this type of chip packaging in semiconductor manufacturing.
