SMT basic noun explanation

Accuracy: The difference between the measured result and the target value.

Additive Process: A method of making PCB conductive traces by selectively depositing conductive materials (copper, tin, etc.) on the plies.

Adhesion: Similar to the attraction between molecules.

Aerosol: A liquid or gas particle that is small enough to be airborne.

Angle of attack: The angle between the screen print surface and the screen print plane.

Anisotropic adhesive: An electrically conductive substance whose particles pass current only in the Z-axis direction.

Annular ring: A conductive material around the borehole.

Application specific integrated circuit: A circuit that is custom made for a specific purpose.

Array: A group of elements, such as: solder balls, arranged in rows and columns.

Artwork: A conductive wiring diagram of a PCB used to produce a photo original, which can be made in any ratio, but is typically 3:1 or 4:1.

Automated test equipment: In order to evaluate performance levels, equipment designed for automatic analysis or static parameters is also used for fault isolation.

Automatic optical inspection: On an automated system, use a camera to inspect a model or object.
